The new version I pushed should work fine. I’m still unable to reach the original author. Some peole like @ygrek and @ytomino are forking and improving the lib. It would be nice to have an official branch of ocurl somewhere. The most advanced is probably @ygrek’s version.

@vbmithr can you pull @ygrek changes in your tree ?

from opam-repository.

Yes I’m going to see what I can do.

Fixed. Please close this issue.

Which OS/version/curl version are you using ?

from opam-repository.

The version of ocurl is 0.5.4 (the only one reported by opam), tested
on OCaml 3.12 and 4.00 (same error).

OS=Debian testing, with the following relevant curl-related libraries installed
(by the way, ocurl 0.5.3 compiles with no error on the same environment)

$ dpkg -l | grep curl
ii curl 7.21.0-1 Get a file from an HTTP, HTTPS or FTP server
ii libcurl-ocaml 0.5.3-2+b1 OCaml curl bindings (Runtime Library)
ii libcurl-ocaml-dev 0.5.3-2+b1 OCaml libcurl bindings (Development package)

Same problem on another machine (not mine), which is Debian stable with the

Well, one problem comes from a
#ifdef HAVE_DECL_CURLOPT_DNS_SERVERS
used in line 5478 of curl-helper.c that should be
#if HAVE_DECL_CURLOPT_DNS_SERVERS

As a side remark, several new features were added to libcurl, and many of them seem not to be tested in the configure script, like for example CURL_VERSION_NTLM_WB which was added in 7.22 (but a simple upgrade of the libcurl libraries fixed the problem, so this is more an issue of declaring properly dependencies on external library, which is a general issue).

I just mailed this bug report to @ygrek ... there is nothing to do on opam-repository until a new upstream release is out.

Version 0.5.5 was just released, that should fix all these issues : https://forge.ocamlcore.org/frs/?group_id=330&release_id=850

I should add that 0.5.3 works for me, at least when installed from the system package manager (I think that version has been removed from opam for some reason).

from opam-repository.

The compilation error you report here is not related to the
opam package, but to your environment, where you seem to have
compiled a version of libcurl that does not provide curl_easy_strerror
(which is really strange, as this is defined in lib/strerror.c
in the sources of curl).

Did you install the development libraries?

On gentoo there is no separate development package. The headers are installed by the main curl package. I just checked, and I do indeed have /usr/include/curl/curl.h with reference to curl_easy_strerror. In comparing to my ubuntu system, the only seemingly significant difference I noticed was that my gentoo box doesn't have libcurl.la (indeed it looks like the package manager explicitly skips installing it).

Ocurl-0.5.3 compiles fine for me. Has there been some change in the way ocurl is building between 0.5.3 and 0.5.5?

from opam-repository.

Digging a little deeper, by changing to the system/build/ocurl-0.5.5 dir and manually running make, I have discovered that the library itself compiles fine, it's during compilation of the examples that this error happens:

make[1]: Entering directory `/opt/opam/system/build/ocurl.0.5.5'

Hi Owen,
it seems you are not linking with the curl C library, that provides
these functions, so
you might try to play with something like

ocamlc.opt -custom -I .. -ccopt -L.. -ccopt -lcurl curl.cma ocurl.cmo -o ocurl

                                                    ^^^^^^^^^^^^^^^

The info on which C library to link with is embedded in the .cma files in
general, so
maybe something is wrong with the meta info in your .cma

Here is what I get on mine:

$ocamlobjinfo curl.cma
File curl.cma

Extra C object files: -lcurl-helper -lcurl

Yep, that looks like the problem. Mine shows:

Extra C object files: -lcurl-helper -lssl -lcrypto -lrt -lssl -lcrypto -lz

and when I add -ccopt -lcurl, the command succeeds.

from opam-repository.

the offending line appears to be this one in the configure script:

CURLLIBS=`curl-config --libs | cut -d ' ' -f 2-`

The cut is removing -lcurl, which in turn is causing it not to end up in the makefile and eventually the .cma

from opam-repository.

curl-config --libs on my system outputs:

-lcurl -lssl -lcrypto -lrt -lssl -lcrypto -lz

which is a bit redundant on the ssl and crypto, but the issue seems to be removing -lcurl from the front.

from opam-repository.

Happy this helped... now, it would be nice to find out why
on your gentoo system you end up with a curl.cma that is
is missing the -lcurl in the metadata, and report the
issue to ygrek upstream (I am cc:ing him just in case) :-)

I see on my ubuntu box that curl-config --libs is:

-L/usr/lib/x86_64-linux-gnu -lcurl

in which case the cut command makes sense. Perhaps we need something more sophisticated, like removing -L but not -l entries. The following seems to work on both my ubuntu and gentoo boxes:

curl-config --libs | xargs -n 1 echo | grep -v -- -L | xargs echo

from opam-repository.

Dear Owen,
that does seem to make sense, so may you write up
a simple summary of the issue you were confronted with,
your proposed patch, and submit it to ygrek who took
over maintenance of ocurl... as soon as he does a new
upstream release, we will have an updated opam package,
and the problem will be solved.
