Hello team,
I attempt to build openshadinglanguage with llvm15 as upstream has yet to support LLVM 16. Can someone have a pointed how to set a cmake parameter for llvm15 and its bitecode validation?
See the spec file on: https://src.fedoraproject.org/rpms/openshadinglanguage/blob/rawhide/f/openshadinglanguage.spec
Have you tried changing the BuildRequires from llvm-devel to llvm15-devel and clang-devel to clang15-devel?
It may autodetect llvm15 if you do that.
Unfortunately it did not as I had to manually set "-DLLVM_ROOT=%{_libdir}/llvm15 \".
The compiling led to the following error:
CMake Error at src/cmake/llvm_macros.cmake:43 (message):
You must have a valid llvm bitcode generator (clang++) somewhere.
Call Stack (most recent call first):
src/liboslexec/CMakeLists.txt:223 (EMBED_LLVM_BITCODE_IN_CPP)
When I try to build from the rawhide branch, I get:
/usr/include/OpenImageIO/detail/fmt/core.h:1691:7: error: static assertion failed: Cannot format an argument. To make type T formattable provide a formatter<T> specialization: https://fmt.dev/latest/api.html#udt
This seems like a failure unrelated to clang. Have you run into this?
-Tom
