To build with latest rapidyaml 0.11.x, the code needs to be patched to use m_error_parse instead of m_error, which was removed in 0.11.0.

The patch, use-rapidyaml-0.11.patch:

Upstream issue and pull request.

Looks like it no longer build with the current rapidyaml version:

/pkgbuild/out/libretro-lrps2-git/src/libretro-lrps2/pcsx2/GameDatabase.cpp:872:23: error: ‘struct c4::yml::Callbacks’ has no member named ‘m_error’

FWIW, I got rid of the old fmt9 dependency based on this comment.

newer-fmt.patch simply adds the mentioned header file to GameDatabase.cpp:

Yes, and you should address your complaints to the rapidyaml maintainer ;)

libryml.so can't be found anymore.

@yyatsuta: You'd probably have to file an issue here https://github.com/libretro/ps2. It probably has nothing to do with the AUR package.

Core crashes for me 90% of the time, without any clear pattern in logs. I'm aware that Software renderer is not supported with Vulkan backend, but this is not the case here - I've tried different renders to no avail. Does anyone else experience this?

Currently running into the following error;

CMake Error at 3rdparty/cpuinfo/deps/clog/CMakeLists.txt:1 (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.

@jclsn: This package is using gnu make which will read MAKEFLAGS variable. You should set that variable in your makepkg.conf with the desired -j flag.

Can you please add -j$(nproc) to the build command?
