configure: error: /bin/bash '/home/tfoundry/.kerl/builds/r14b04/otp_src_R14B04/erts/configure' failed for erts

I am using kerl with SnapCI and when I run CI I get this error:

  $ ./kerl build 17.4 17.4
  There's already a build named 17.4

Must I do some clean up before install a new build ? If so, how is that done ?

Homebrew (a mac package manager) would like a tagged release (all you need to do is push a version number). Would this be possible?

Homebrew/legacy-homebrew#26326
Homebrew/legacy-homebrew#26307

I'm using kerl installed from homebrew on OSX, brew takes it from master.

%kerl list builds
R16B03-1,r16b03-1
%kerl delete build r16b03-1
No build named r16b03-1
%kerl delete build  R16B03-1
No build named  R16B03-1

On my other machine, I've resorted to deleting the ~/.kerl directory, but that's kinda clunky.
Same old story, I built Erlang for 32 bit OS, need to delete.

Add support for specifing apps to build via KERL_CONFIGURE_APPLICATIONS

Tested with R15B01.

  $ time env KERL_BUILD_APPLICATIONS="kernel sasl stdlib" ./kerl build R15B01 r15b01-minimal

  real  3m19.337s
  user  2m7.814s
  sys   0m46.658s

  $ time ./kerl build R15B01 r15b01-default

  real  9m35.498s
  user  7m30.770s
  sys   1m21.905s

Please see the commit below.

https://github.com/norton/kerl/commit/b9d54c52ac497032f1c2be68aa2471409f227d0d

The end results of configure tells you if any applications in otp will be skipped due to missing dependencies. It would be nice if kerl could capture and present this information during building.

Hi,

I have problems building R16B02 on Mac OS X 10.8.5.

Looking at the log I see pretty early on

...
can't open x86_64-apple-darwin12.5.0/opt/plain/erl_compile_flags.h for writing at utils/make_compiler_flags line 65.
...

And I have similar errors further down.

BUT, I have no problem installing R14B04 or R15B03, therefore I suspect there is something wrong with how kerl tries to build R16B02. It seems some path is bad, but I'm new to Kerl so I dont know where to look and change.

How come R14B04 works but not R16B02?

After updating my clone of kerl I noticed that kerl status, prompt and active commands no longer work but only with old installations.

This is the cause: 9cf83c9#diff-75743bad0452412b658dabebd6b439f4R653
so now what one should do to make it work with old installations (those installations that are made before the commit I mentioned above) is appending the following to the activate file of each installation

_KERL_ACTIVE_DIR="/path/to/otp-installation"
export _KERL_ACTIVE_DIR

Porting issue from evax/kerl#13

If libssl headers are missing in the system, the resulting Erlang build will not include crypto module. Such Erlang build is pretty much useless. For instance, rebar won't be working without crypto.

It would be great if kerl were asking a user whether he wants to continue a build without crypto. A simpler but a still better way of handling this situation would be exiting with an error.

Hi,

Please can you include some kind of license for this project?

It took me some time to find that one has to enter kerl build git .. to start a build from git. Maybe the usage information for git should also be output when entering kerl build. Example:

usage:
    kerl build <release> <build_name>
    kerl git <git_url> <git_version> <build_name>

Hi

Looks like they've changed the release numbering format:
See http://www.erlang.org/download/otp_src_17.0.tar.gz

So this sed no longer works?
sed $SED_OPT -e 's/^.<[aA] [hH][rR][eE][fF]="/download/otp_src(R1[-0-9A-Za-z_]+).tar.gz">._$/\1/' \

I could be wrong ;)

From a fresh install of Ubuntu 11.10 kerl failed to build R14B04. The build log shows:
configure: error: No curses library functions found
configure: error: /bin/bash '/home/bryanhunter/.kerl/builds/r14b04/otp_src_R14B04/erts/configure' failed for erts

I did a "sudo apt-get update" and tried to build with kerl again and it failed in the same way.

I then did a "sudo apt-get -y install libncurses5-dev". I tried again after that, and everything builds successfully.

Let me know if you need more info (I have a VM snapshot where I can reproduce the problem). Next week I can poke around in kerl. If I'm not too out of my depth and I manage to fix it, I'll send you a pull request.

I was attempting to use kerl build git ... to build and install Erlang; the build appeared to succeed but kerl install ... failed with Couldn't install Erlang/OTP git (ei-73fc7ca) in /home/roger/erlang/ei-73fc7ca.

It turns out that it's because I had ERL_TOP set (from earlier messing around with building Erlang from source), and that kerl was actually building that copy of Erlang. So when it went to install from ~/.kerl/builds/ei-73fc7ca, it wasn't actually built.

Either kerl should warn if ERL_TOP is already set, or it should be sure to set it correctly in kerl build git....

I want to set a CFLAGS (env) parameter in KERL_CONFIGURE_OPTIONS inside .kerlrc with the value as: CFLAGS="-g -C0 -fstack-protector" (Note that CFLAGS value includes whitespaces); could this be possible?

I guess this is rather a shell scripting issue (of source .kerlrc), but I'd be glad if I can obtain a hint. Thanks in advance.

Using kerl, scripts that should be executable with escript fail with

/usr/bin/env: escript: No such file or directory

Installed kerl from trunk as of a few minutes ago.

Ran a basic build of R13B03 and got a weird error/success response. Went to install this build and ended up getting a flat out error.

Hi,

I had a thought: the most common use case for kerl is to install various versions of Erlang, why not make that really simple to do by removing some of the 'extra' steps? For example:

kerl build-install git https://github.com/erlang/otp.git OTP-17.1.2 17.1.2

Builds and installs in .kerl/installations/17.1.2/

I was on a train with no network. I re-installed a previous build to see if I could install the documentation:

kerl install r16b02

it failed (obviously) with curl failures.

But when that happened it didn't clean up the output, I had 2 files in my .kerl/archives that were artifacts of the attempt.

You could use curl -f and detect failures and clean up files.

That's 119 warnings / errors.

Since .kerlrc is read by the source command of shell, using export to set environmental variable will affect the later shell commands after activating a kerl-built OTP installations. This should be notified in the document. See #49 too.

Automatic installation of manpages could be supported for tarball installations, using the other downloads provided by erlang.org. At least, a reference to them should be made in the README file.

Install manpages for R14B03:
curl http://www.erlang.org/download/otp_doc_man_R14B03.tar.gz | tar xzf - -C path/to_R14B03

I installed my Erlang installation in ~/.erlang/r16b01 which causes an error when using this installation

e:path_eval([".","/Users/phil"],".erlang"): illegal operation on a directory

after moving the installtions to ~/erlang/r16b01 everything works fine. Seems like there is problem setting up the path if it contains a dot.

Howdy!
I am trying to use kerl to manage my erlang releases.

I did a clean install of R15B03, and R16B02.
When trying to compile c ports (for example syslog) I get the following error:

rebar compile

For good measure I made sure rebar was compiled with the kerl managed versions of erlang (just to be safe).

Is kerl doing something clever with respect to erl_interface?

I am on new Macbook Air, running MacOSX 10.8.5.

Everything works fine when on an ubuntu laptop...

Any tips and suggestions what I could try? I looked through the kerl command, and I cannot really discover what it is that might be going wrong. Maybe someone with more intimate knowledge of the kerl internals knows something I have been missing that could help me on the way?

Thanks!

I added an experimental new 'clone' command to your handy kerl tool. This command copies a kerl managed installation directory to a specified remote host and directory. This command relies on ssh, rsync, and having password-less ssh access to the specified remote host.

The purpose of this command is to allow one to easily copy a kerl installation to a cluster of nodes.

I'd appreciate your review and comments. I understand this 'clone' command might not be appropriate for inclusion to the official kerl tool.

Please see the commit below.

CentOS 6.2

I get the below error when trying to run a bamboo build. Verified that activate command runs before running "make rel".

02-Nov-2014 09:26:31 The current active installation is:
02-Nov-2014 09:26:31 /opt/erlang/17.1

02-Nov-2014 09:26:32 erlc -o apps/ejabberd/priv/mibs apps/ejabberd/mibs/EJABBERD-MIB.mib
02-Nov-2014 09:26:32 make: execvp: erlc: Permission denied
02-Nov-2014 09:26:32 make: *** [apps/ejabberd/priv/mibs/EJABBERD-MIB.bin] Error 127

Tried to run the command after logging into the box and the same error when I don't run source /opt/erlang/17.1/activate command. When I run the command and run make rel, I don't see the above error.

This happens only in the context of the build agent which has full access (also owner) to /opt/erlang/17.1 directory. Not sure what I'm missing.

Anyone has a workaround or have seen this issue before?

$ chmod a+x kerl
$ ./kerl build 17.4 17.4
17.4 is not a valid Erlang/OTP release

Any idea what is wrong ? Trying it on my local box works.

I've got 17.3 and 17.3.4 installed using kerl. I'm using 17.3, and kerl prompt returns

 (17.3
17.3.4)

I was expecting it to return only (17.3)

Right now, kerl compiles each Erlang runtime from source when kerl build and kerl install are called. This is a rather time-consuming process, and this makes harder and harder to support multiple versions of Erlang on Travis CI.

Tremendous amount of time will be saved if kerl can install from binary packages offered by Erlang Solutions. (Ubuntu packages are of most interest to Travis CI.) Some binary packages are not conducive to side-by-side installations, but some hacks may be possible.

I've previously built the following OTP with SSL support (required by rebar )

r15b01
r15b02
r15b03
r16b03
r17.0

But for some reason when I try to build R18.1 - AFAIK using the same ~/.kerlrc and build method - it now fails to build with SSL support.

[/basho/meck%]. /erls/r18.1/activate
[/basho/meck%]erl -eval "crypto:start(), halt()." -noshel

}]}}

Crash dump is being written to: erl_crash.dump...done
init terminating in do_boot ()

I've got the following ~/.kerlrc and I even tried source ~/.kerlrc before running the usual build and install commands:

kerl build 18.1 R18.1  
kerl install R18.1 /erls/r18.1

export KERL_CONFIGURE_OPTIONS="--disable-hipe --enable-smp-support --enable-threads --enable-kernel-poll --
enable-darwin-64bit"
export CFLAGS="-DOPENSSL_NO_EC=1"

I've deleted the ~/.kerl directory and repeated the steps but it just doesn't seem to be including 'crypto'.

Can anyone suggest something else I could try, desperate to get R18 built and activated.

Providing --enable-hipe as in KERL_CONFIGURE_OPTIONS will build the erlang release without hipe if M4 is not installed.

Currently kerl does a mkdir -p and checks if the target dir is a directory.

It should also check if the directory is empty and refuse to install in nonempty directories.

This avoids messing up and even overwriting directories that e.g. have been accidentially specified.

Since "delete installation" just does a rm -Rf after checking for activate this can get disastrous. E.g. installing by accident in ones home dir, noticing the error and deleting it again => home dir erased

Even if a kerl installation is activated, the output of kerl status does not reflect it and says no kerl is activated. Note that _KERL_SAVED_MANPATH and _KERL_SAVED_PATH do not exist.

Environment: OS X 10.9.1, zsh 5.0.5.

The function get_newest_valid_release() does not work properly with the new versioning scheme. The newest version is not at the end of the file and the introduction of release candidates complicates the sort order.

The following (not soo pretty) implementation works as expected. Any other suggestions? ideas?

get_newest_valid_release()
{
    check_releases
    reltail=`cat $KERL_BASE_DIR/otp_releases | sed -e "s/^R\(.*\)/\1/" | sort | tail -1`
    relbase=`echo $reltail | sed -e "s/^\(.*\)-rc.*/\1/"`
    for rel in `cat $KERL_BASE_DIR/otp_releases | grep -x $relbase | tail -1`; do
        if [ ! -z "$rel" ]; then
            echo "$rel"
            return 0
        fi
    done
    for rel in $reltail; do
        if [ ! -z "$rel" ]; then
            echo "$rel"
            return 0
        fi
    done
    return 1
}

Is it possible to add to kerl a possibility to obtain an "unstable" Erlang build from its public repository?

Having recently installed Erlang via kerl on a Fedora machine I've noticed the following, which might be of help for someone.

By default, the sudoers configuration for Fedora doesn't keep the value of the $HOME variable, which is used by kerl script.

This means that if you run the kerl build command from normal user, sudoing just to run the kerl install command, this will fail, kerl not being able to find any build:

$ ./kerl build R15B01 r15b01
Getting the available releases from erlang.org...
[...]
Agner has been successfully built
$ sudo ./kerl install r15b01 /opt/erlang/r15b01
No build named r15b01
$ ./kerl build R15B01 r15b01
There's already a build named r15b01
./kerl list builds
R15B01,r15b01

I understand this is not a bug in kerl, but it would be useful to provide a more verbose output to the user, for example showing where kerl is looking for builds.

It appears activate requires the full path which is semi annoying. Would be nice if activate allowed the use of relative paths.

Example

./erlang/r15b/activate doesn't work but...

. /home/tburdick/erlang/r15b/activate does

Would like the first method to work.

i chmod u+x /Users/yy/erlang/r15b02/activate

and excute /Users/yy/erlang/r15b02/activate

just get:

zsh: command not found: erl

please help..

I find it a little annoying that I have to pull in rebar separately.

If I build an erlang would it not be useful to mix in rebar?

For some reason , I want to build 32 bit erlang version on my OSX

Some users may have a value defined and that can make the build fail as per http://erlang.org/pipermail/erlang-questions/2014-April/078526.html and recent Twitter comments. Should probably set GREP_OPTIONS='' in kerl directly.

Putting this here so it's not forgotten as neither of us have time to work on it right now.

After a successful build when I install it can not find agner:

I checked to see if agner existed anywhere under .kerl and it does not:

Is kerl intended to manage Erlang versions? It makes it easy to install different versions of Erlang easy but management of versions is hard. For example suppose I have Erlang 16 and Erlang 17 installed. To use Erlang 17 I must run . ~/.kerl/builds/17.1/release_17.1/activate. Then I can use Erlang 17 in the current session. If I start another session and what to use the same version of Erlang I must run the same command again.

Is kerl meant to be used to manage Erlang versions? Or is there another piece of software used for switching between Erlang versions that I should be using?

If kerl is meant to be used for management of Erlang versions I see many ways in which it can be improved (for example, it could be updated so kerl activate 17.1 could be run instead of . ~/.kerl/builds/17.1/release_17.1/activate). I would happy to create a PR that adds this functionality to kerl.

Hello,

If you do the following with current kerl it fails to compile everything natively:

KERL_CONFIGURE_OPTIONS=--enable-native-libs kerl build 17.0 17.0_native
kerl install 17.0_native ~/erlang/17.0_native
. /home/essen/erlang/17.0_native/activate
% erl                                          
Erlang/OTP 17 [erts-6.0] [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V6.0  (abort with ^G)
1> code:is_module_native(lists).
false
2> 

The reason for this is best explained in this email: http://erlang.org/pipermail/erlang-questions/2014-April/078460.html

Modifying kerl this way made it work as expected:

    if [ -n "$KERL_USE_AUTOCONF" ]; then
        ./otp_build autoconf $KERL_CONFIGURE_OPTIONS > "$LOGFILE" 2>&1 && \
            ./otp_build configure $KERL_CONFIGURE_OPTIONS > "$LOGFILE" 2>&1
        make clean
        ./otp_build configure $KERL_CONFIGURE_OPTIONS > "$LOGFILE" 2>&1
    else
        ./otp_build configure $KERL_CONFIGURE_OPTIONS > "$LOGFILE" 2>&1
        make clean
        ./otp_build configure $KERL_CONFIGURE_OPTIONS > "$LOGFILE" 2>&1
    fi

However this may or may not be something you guys want. AFAIK it's only needed for native libs so perhaps this can only be done then?

Hello everyone,

After installing erlang with kerl using "kerl install 18.2 ~/.erlang", the installation worked fine but everytime that I interact with erlang I get an error, because of the folder name. The error is:

file:path_eval([".","/home/dguedes"],".erlang"): illegal operation on a directory

After installing in a folder without dot (".") in its name, everything worked fine.

cheers.
