Bug Report Unable to compile on Arch

[Ranko Kohime]

A month or so ago (I'm not certain exactly when, as I've had little time behind the keyboard these past 2 months), OBS stopped compiling on my Arch box. I get the same error whether I try to compile manually, or through the "obs-studio-git" package in the AUR.

Linking CXX executable obs
/usr/bin/ld: /usr/local/sbin/../lib/libcurl.a(libcurl_la-content_encoding.o): undefined reference to symbol 'inflateInit2_'
/usr/bin/../lib64/libz.so.1: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

make[1]: *** [obs/CMakeFiles/obs.dir/all] Error 2
Makefile:136: recipe for target 'all' failed
make: *** [all] Error 2

GCC version is 5.1.0-4, if that matters, and I added "-DUNIX_STRUCTURE=1" to the pkgbuild as suggested by one of the comments in the AUR, but I still get the same error.

Looks like a dependency issue. I don't quite know how to help in most of these cases on different linux distributions, but I'm guessing there's an issue with the lubcurl dependency.

If "obs-studio-git" didn't make it, have you tried with "obs-studio" instead in AUR ?

I didn't even see that in the error text the first time I read it. But even rolling the curl package (there is no libcurl in Arch) back to the version that last successfully compiled didn't succeed.

I tried that just now, and unfortunately, same error.

Suspecting bitrot, I installed a fresh copy of Arch in a VM, and tried compiling there, which succeeded, but I got a core dump trying to run it. (error: ARB_GLX_create_context not supported!) I kind've expected that running in a VM without any hardware pass-through, but not sure if that's supposed to be that way.

Anyway, I looked at the list of dependencies obs-studio-git pulls in on a fresh, bare-bones install, and deleted my package cache and had pacman re-install all of these packages on my main system, but still no change in the compile error.

I then copied the built pkg.tar.xz file over from the VM to my main system, and installed that with pacman, and strangely enough it works just fine.

Trying obs-mp in a VM is useless, there are no VMs with Opengl 3.2+ support.

Well, I fixed this, and managed to build on my machine, and I don't understand why this was a thing.

/usr/bin/ld: /usr/local/sbin/../lib/libcurl.a(libcurl_la-content_encoding.o): undefined reference to symbol 'inflateInit2_'

libcurl.a is not owned by any package on my system, Google doesn't give me a clear answer of what this was supposed to have been owned by, and renaming it allowed the build to complete successfully.
