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:

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.

Do you have -Wp,-D_GLIBCXX_ASSERTIONS in your CXXFLAGS? I can reproduce with this added to CXXFLAGS. This is not enabled by default in Arch, so please remove it if you added it. That being said it's probably worth reporting this upstream, it might be a real bug.

My GCC version is 11.1.0-1 and glibc is on version 2.33-5.

I didn't get to mention it earlier, but I was expecting fewer issues since I recently switched to Manjaro's Unstable branch, so I should be at Arch Linux's pace. I also tried to check any Pacman updates if there were any glibc, CMake, Git, or Python updates - but none was pending.

IIRC, I would always stumble around either libdecaf/bctoolbox-git (but that was also before I had an AUR account and I never tried putting in more than a few minutes of effort.)

What's your gcc version? It builds and tests fine with gcc 11 here.
