I managed to build it by preventing the includes from sys/* in mono/metadata/w32file-unix.c

This patch might become obsolete as soon as https://sourceware.org/git/?p=glibc.git;a=commit;h=774058d72942249f71d74e7f2b639f77184160a6 will be included in the next glibc release.

Thanks!

@FabioLolix Ok, updated .SRCINFO to 6.12.0.173.r1404.5977f1ca545 (Mono JIT compiler version 6.13.0)

Would you like to bump the pkgbuild? One pkgbuild I'm working on need a very recent build, solve this problem https://bugs.archlinux.org/task/71007 I had

@FabioLolix Thanks was not familiar with devtools, that worked where yay/makepkg did not

builds fine here both using makepkg and devtools

Getting some build errors.

Thank you @hugegameartgd, now is working and takes 45 minutes to build in GitLab CI pipeline.

@carlosal1015 Should be fixed now, see https://aur.archlinux.org/cgit/aur.git/commit/?h=mono-git&id=fccbec145e0856b7ad66589c674ce989e6cb2e6e
