[272/272] Linking CXX executable zig
wink@wink-desktop:~/prgs/ziglang/zig2/build
$ ./zig version
0.4.0+0f8fc3b9
What's happening is Arch Linux has both static (libLLVM[[:alpha:]]+.a) and shared (libLLVM-8.so) libLLVM* libraries for LLVM. But it has only shared libclang[[:alpha:]]+.so libraries with the full C++ API for CLANG . Because of the logic in cmake/Findllvm.cmake when CMAKE_BUILD_TYPE is NOT "Debug" zig prefers static libraries for LLVM:
if(NOT(CMAKE_BUILD_TYPE STREQUAL "Debug") OR ZIG_STATIC)
execute_process(
COMMAND ${LLVM_CONFIG_EXE} --libfiles --link-static
OUTPUT_VARIABLE LLVM_LIBRARIES_SPACES
OUTPUT_STRIP_TRAILING_WHITESPACE)
string(REPLACE " " ";" LLVM_LIBRARIES "${LLVM_LIBRARIES_SPACES}")
...
So we get the libLLVM[[:alpha:]]+.so files statically linked to zig0:

But for CLANG we get shared libraries:
-- Found CLANG: /usr/lib/libclangFrontendTool.so;/usr/lib/libclangCodeGen.so;/usr/lib/libclangFrontend.so;/usr/lib/libclangDriver.so;/usr/lib/libclangSerialization.so;/usr/lib/libclangSema.so;/usr/lib/libclangStaticAnalyzerFrontend.so;/usr/lib/libclangStaticAnalyzerCheckers.so;/usr/lib/libclangStaticAnalyzerCore.so;/usr/lib/libclangAnalysis.so;/usr/lib/libclangASTMatchers.so;/usr/lib/libclangAST.so;/usr/lib/libclangParse.so;/usr/lib/libclangSema.so;/usr/lib/libclangBasic.so;/usr/lib/libclangEdit.so;/usr/lib/libclangLex.so;/usr/lib/libclangARCMigrate.so;/usr/lib/libclangRewriteFrontend.so;/usr/lib/libclangRewrite.so;/usr/lib/libclangCrossTU.so;/usr/lib/libclangIndex.so
So zig0 has statically linked libLLVM[[:alpha:]]+.a but to be able to link the CLANG shared libraries it needs libLLVM-8.so as can be seen in the ldd output:

So we end up with two copies of the LLVM libraries, one static and one dynamic and so executing zig0 fails.
There are various work-arounds:
- Use only Debug
- Build llvm from source.
- Or as Duncan suggested tweak CMakelists.txt
In my opinion those work-arounds aren't great. I think all LLVM related libraries, static or shared, should be linked to zig the same way and the user should be able to control which.
Other thoughts?
