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.

When installing with $ makepkg -si, I receive the same error in check() as described by loglog. When I check ~/AUR/libdecaf/src/build/Testing/Temporary/LastTest.log, I see the same basic content that inslee reported.

Can anything be done about this error?

I thought I was doing pretty well this time around when trying to install linphone-desktop-git manually (since it is currently the only updated non-AppImage Linphone Desktop package), but this halted my progress 5 out of 9 packages of the way through. This is becoming the bottleneck in my process, and I am trying to install the remaining packages in this order: libdecaf, bctoolbox-git, lime-git, liblinphone-git, and linphone-desktop-git.

I am getting a build failure:

The upgrade worked after a larger series of updates came down through Manjaro Stable (there were a lot of updated packages but the list is here: https://forum.manjaro.org/t/stable-update-2021-05-19-kernels-nvidia-kde-frameworks-plasma-systemd-libreoffice-kde-gear-mobile-ff-tb/67002)

For those that were having issues on Manjaro before, try updating libdecaf after downloading those updates.

I don't get this error, so hard for me to say anything. The assertion is not very helpful unless you can point the line in the code that triggers it. This seems like something you should report upstream.

Same error here, caused by a failed assertion:
