I can fix that. > > I tested with: > meson -Ddri-drivers= -Dgallium-drivers=r600 -Dopengl=true -Dplatforms=x11 > -Dopencl=true > > meson asked for libdrm_amdgpu dependency even though I'm only building > clover+r600g driver. That's probably because you didn't add `-Dvulkan-drivers=`, since radv does depend on libdrm_amdgpu. If you add that and still get a request for libdrm_amdgpu let me know and I'll look into it further. > after a bit of fiddling with PATH and PK_CONFIG_PATH to pick up the latest > llvm/liblclc > linking failed with: > src/gallium/auxiliary/libgallium.a(gallivm_lp_bld_misc.cpp.o):(.data.rel.ro._ZTI26DelegatingJITMemoryManager[_ZTI26DelegatingJITMemoryManager]+0x10): > undefined reference to `typeinfo for llvm::RTDyldMemoryManager' > collect2: error: ld returned 1 exit status > > this looks like it did not pick up the rtti setting from llvm-config: > $ ~/.local/bin/llvm-config --has-rtti > NO > $ ~/.local/bin/llvm-config --cxxflags | grep -o fno-rtti > fno-rtti > > rtti setting is quite messy since clover uses dynamic_cast.

I'm not sure what the right way to solve this is, maybe to cache any relavent environment variables between runs in meson itself, since pkg-config has the same problem with PKG_CONFIG_PATH. ATM there is no way to implement the llvm-prefix in meson the way it is in autotools. > > in the end I got meson built clover to run (clinfo + simple demo) on my > turks with these changes: > * build and install libdrm_amdgpu -- should not be necessary for r600g > only build > * switch to distro (fedora) provided libclc and llvm -- avoids rtti > build problem (note libclc is just tagging along llvm since my local > builds install headers to the same location) > * fiddle with pipe-loader dir, for some reason LIBGL_DRIVERS_PATH did > not work when pointed to meson built pipe_r600.so.

I'm not certain, though Curro probably knows, but the dynamic pipeloader is hard-coded to search $install/$libdir/gallium-pipe for pipe drivers, so you may need to run ninja install to make it work. Alternatively LD_LIBRARY_PATH might work as well. Dylan
