Arch Linux User Repository

Please remove -1.0.2 from sources download. Currently you'd have do redownload whole repo on version bump which is wasteful.

now ok

@simona, can you checked with the new version I just pushed? If it still doesn't work, can you let me know which version and name of the compiler you're using. I can't reproduce on my side.

Fails with

CMake Error at CMakeLists.txt:8 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

Thanks very much! The diff works for me, I was able to compile the package :)

The package fails to build due to -Warray-bounds being treated as error. This patch did the trick for me:

diff --git a/PKGBUILD b/PKGBUILD

Dr Google tells me it has something to do with GCC? I have plenty of RAM free, so I'm not running out.

After reading the Arch Wiki makepkg article and commenting out the line that contained #CXXFLAGS="$CFLAGS -Wp,-D_GLIBCXX_ASSERTIONS" in /etc/makepkg.conf, I was able to install libdecaf. Thank you!

It seems like that CXXFLAGS was added to Manjaro by default.
