Error building on Windows: "make[1]: fltk-config: Command not found" about fltkhs HOT 15 CLOSED

(the error was at the last step, stack install )

from fltkhs.

It's failing because it can't find fltk-config which should have been built with fltk. From the fltkhs-hello-world project root, what is the output of find .stack-work -name "fltk-config"?

from fltkhs.

I can replicate this issue. Thanks!

I encountered the same issue on Debian. Installing from source works, but the bundled path lead to the error mentioned above. So it appears it's got more to do with the integration of the bundled lib than with the OS. My build output just around the first error was

checking for strtol... yes
: creating ./config.status
config.status: creating Makefile
config.status: creating c-src/Makefile
config.status: creating c-examples/Makefile
config.status: creating fltkhs.buildinfo
: WARNING: unrecognized options: --with-compiler
==Compiling C bindings==
make[1]: fltk-config: Command not found

And greping the output for warnings revealed

configure: WARNING: Ignoring libraries " -lSM -lICE" requested by configure.
configure: WARNING: could not find the required Xft headers and/or libraries.

So maybe that's something?

Environment: Debian 8.8, kernel 3.16.43-2, GHC 8.0.2, stack 1.1.2, cabal-install 1.24.0.2, gcc 4.9.2, make 4.0, autoconf 2.69, automake 1.14.1

I tried it twice, first with an ancient version of FLTK installed, then without any system FLTK. Same result. I don't know what else to look for, so let me know if you need anything else.

This is great info, thanks! I must admit I only tested on my home machine which runs Arch so I had no idea. What worked there was just updating various environment variables once the bundled library was built. Obviously that's not working.

I'm not sure I understand what's going on, but following the code you linked to I searched my log again. The updated PATH now starts with /tmp/stack7015/fltkhs-0.5.1.6/fltk-1.3.4-1:/tmp/stack7015/fltkhs-0.5.1.6/fltk-1.3.4-1/fluid: I'd expect the library to be built somewhere in .stack-work. So maybe these paths get confused or the working directory is not changed correctly at some point?

from fltkhs.

I believe you've hit on the root cause. It's doing what you expect on one my machines (building in .stack-work) but not on others. I'll look into it. Thanks!

I think I have it fixed. @sboosali @MarLinn can you help me test? Please clone the fixes branch of fltkhs-hello-world (git clone -b fixes https://github.com/deech/fltkhs-hello-world) and try stack build --flag fltkhs:bundled?

(i'll be away from my computer for a week, though i'll try to install it if a windows computer is available)

feel free to ping me before future releases, since i do half my haskell work on windows anyways.

from fltkhs.

I've cut a new release. I think (hope) this is now fixed. If you get around to testing and you agree please close this issue.

from fltkhs.

I tried it on a fresh Haskell install on Windows , and it worked!

from fltkhs.

btw, for the windows documentation:

there's a typo in the documentation ("pacmay"), and I'd tell the user what widget to expect from the launching the executable (a window with a button to toggle). also, we should batch the commands into a script, that can be copied/pasted. and a "force yes" option for pacman?

from fltkhs.

Batching the Windows install is a great idea! For now I've fixed the spelling and also some other bugs. Recommend pulling the latest version of fltkhs-hello-world and doing stack build --flag fltkhs:bundled.
