equivalent option in clang for gcc --exclude-libs

Hi,

I am creating a shared libary from some objs and a static libary ( e.g., llvm, a 3rd party static lib ). the static library is only used by functions in the objs, and is not intended to be exposed to shared library clients. so, I do not want to export symbols in the static library, to avoid potential name conflict when this static library is also linked into other shared libraries.

with gcc, I am using --exclude-libs to remove symbols in static library.

while with clang, it seems there is no such equivalent option.

my questions are that:

  1. are there any equivalent options in clang, but with different name?

  2. if not, are there any workaround ( besides adding export/import declaration in the source code of the static library, which is out of my control ) ?

  3. I am pretty sure that linux is using a common name space for shared library symbols, which tends to cause name conflicts. what about maci and windows?

Your help is really appreciated!

Thanks,

–exclude-libs is a linker option. gcc just happens to pass it through for you. Clang will do the same if you escape it with something like -Wl,–exclude-libs,ALL.

I did compile using -Wl,–exclude-libs,ALL. it passed on linux, but failed on maci. the linker command on maci is:

xcrun -sdk macosx10.7 clang++ … -Wl,–exclude-libs,ALL

error message:

ld: unknown option: --exclude-libs

seems like that is not because clang is missing the option, but because maci xcode linker does not support the option?

any suggestions?
