Regarding lot of undefined symbols while building xeus-cpp against emscripten

[anutosh491]

Few days back I had opened compiler-research/xeus-cpp#159 to discuss the above topic.

I hope xeus-cpp is expected to be abstracted away from any libraries coming out of llvm/clang which means eventually we might only want to link with clangcppInterOp but when I build xeus-cpp using emscripten we end up with lot of undefined symbols

As I made a note on the other issue, these are coming out of these 8-9 libraries

libLLVMWebAssemblyCodeGen.a - for first 4
libLLVMSupport.a
libLLVMOrcJIT.a
libLLVMObject.a
libclangAST.a
libclangInterpreter.a
libclangLex.a
libclangBasic.a

[anutosh491]

Now I see this

CppInterOp/lib/Interpreter/CMakeLists.txt

Lines 37 to 44 in 757e7e8

	set(link_libs
	${cling_clang_interp}
	clangAST
	clangBasic
	clangFrontend
	clangLex
	clangSema
	)

Which hopefully links these against clangcppInterop (I see quite some common like above we have clanglex, clangbasic, clangast which are a part of link_libs too) so I guess we shouldn't be expecting missing symbols out of these ?

Or am I missing something ?

[anutosh491]

The llvm recipe on emscripten-forge is pretty clean now and provides all of the libraries that might be essential (under PREFIX/lib)

So I don't think its a problem out of the llvm recipe on emscripten-forge.

The CI building xeus-cpp in cppinterop show even more undefined symbols. Can be seen here

[anutosh491]

A shared build for CppInterOp should solve this
