@dreleck @alerque: Both removed, thanks for the suggestions =)

The conflicts=() can be dropped as well, they are automatically reciprocal and according to the guidelines the VCS variant should be the one to declare this.

Can you remove the libusrsctp-git provides entry? It should be the other way round: libusrsctp-git should provide libusrsctp.

Thanks for maintaining!

I have pushed an update to the PKGBUILD which should fix all the current build issues, and make it more resistant to changes in default compiler warnings when the compiler packages are updated. Please let me know if you find further issues =)

The given package does not build, like the comment below already said.

Removing the configure-flag "--disable-debug" from PKGBUILD gives the Error:

397 | # warning _FORTIFY_SOURCE requires compiling with optimization (-O)

This results in following solution:

Adding "-O" to _EXTRA_FLAGS in PKGBUILD leads to a buildable package.

Does not compile using GCC 11.1.0:

These PKGBUILD lines don't work if the values in /etc/makepkg.conf are split across multiple lines (which is the case in the default). Maybe bash-source makepkg.conf and echo the value instead?

  eval "$(sed -e '/^CFLAGS=/p' -e d /etc/makepkg.conf)"
  eval "$(sed -e '/^CXXFLAGS=/p' -e d /etc/makepkg.conf)"
  eval "$(sed -e '/^LDFLAGS=/p' -e d /etc/makepkg.conf)"

@dimtych: I think it may be worth it to raise an issue to the developers, trying to build from the Git master branch also fails, and this seems like a legit case in which the compiler is detecting a problem in the code.

Should I post the bugreport to authors?
