[llvm-dev] PIC version of libclang.a is not installed

[Han Zhu via llvm-dev]

Hello,



I need a PIC version of libclang.a so I passed LIBCLANG_BUILD_STATIC=ON to
cmake (LLVM_ENABLE_PIC is default to ON). I then saw both libclang.a and
libclang.so built under /lib, which is expected. But libclang.a was not
installed and only libclang.so was. This was a bit surprising. To debug, I
printed out the cmake commands of AddClang.cmake using


`cmake -G Ninja -DLIBCLANG_BUILD_STATIC=ON --trace-expand
--trace-source=AddClang.cmake -Wno-dev`


and checked the install command:


`install(TARGETS libclang COMPONENT libclang EXPORT;ClangTargets LIBRARY
DESTINATION lib ARCHIVE DESTINATION lib RUNTIME DESTINATION bin )`



It has both ARCHIVE and LIBRARY specified so it should install both .a and
.so? I don’t know where to go from here. Has anyone had similar issue with
this? Why is PIC libclang.a not installed?



Thanks!

Han Zhu
