Hello team,
Building the latest stable osl 1.11.15 failed on all Fedora version except Release 33 due to error caused by llvm 12.
The following result from Rawhide highlight the cause:
~~~
/builddir/build/BUILD/OpenShadingLanguage-Release-1.11.15.0/src/liboslexec/llvm_util.cpp: In member function 'void OSL_v1_11::pvt::LLVM_Util::write_bitcode_file(const char*, std::string*)':
/builddir/build/BUILD/OpenShadingLanguage-Release-1.11.15.0/src/liboslexec/llvm_util.cpp:2992:69: error: 'F_None' is not a member of 'llvm::sys::fs'; did you mean 'OF_None'?
2992 | llvm::raw_fd_ostream out (filename, local_error, llvm::sys::fs::F_None);
| ^~~~~~
| OF_None
Looks like F_None is (was) a compatibility spelling, I didn't dig but I bet what it should be changed to is in here somewhere:
/builddir/build/BUILD/OpenShadingLanguage-Release-1.11.15.0/src/liboslexec/llvm_util.cpp: In member function 'bool OSL_v1_11::pvt::LLVM_Util::ptx_compile_group(llvm::Module*, const string&, std::string&)':
/builddir/build/BUILD/OpenShadingLanguage-Release-1.11.15.0/src/liboslexec/llvm_util.cpp:3054:13: error: 'class llvm::TargetOptions' has no member named 'StackAlignmentOverride'
3054 | options.StackAlignmentOverride = 0;
| ^~~~~~~~~~~~~~~~~~~~~~
Looks like this was removed/renamed as well:
Thanks,
Richard
