Attempt to fix wasm-ld undefined symbols #1

Open anutosh491 opened 4 hours ago

anutosh491 commented 4 hours ago

  1. LLVM build from emscripten-forge looks good

    anutosh491@Anutoshs-MacBook-Air lib % nm -C libclangInterpreter.a --defined-only | grep __clang_Interpreter_SetValueNoAlloc
00005cf4 T __clang_Interpreter_SetValueNoAlloc

  2. Shared library for CppInterOp (libclangCppInterOp.so)

set_property(GLOBAL PROPERTY TARGET_SUPPORTS_SHARED_LIBS TRUE) set(CMAKE_SHARED_LIBRARY_CREATE_C_FLAGS "-s SIDE_MODULE=1 -shared -s EXPORT_ALL=1 -s LINKABLE=1 -Wl,--export-all") set(CMAKE_SHARED_LIBRARY_CREATE_CXX_FLAGS "-s SIDE_MODULE=1 -shared -s EXPORT_ALL=1 -s LINKABLE=1 -Wl,--export-all") set(CMAKE_STRIP FALSE)

add_llvm_library(clangCppInterOp SHARED

CppInterOp.cpp DynamicLibraryManager.cpp DynamicLibraryManagerSymbol.cpp Paths.cpp

Additional libraries from Clang and LLD

LINK_LIBS "-Wl,--whole-archive" clangInterpreter "-Wl,--no-whole-archive" )

Append EXPORTED_FUNCTIONS to existing C and C++ compiler flags

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -s EXPORTED_FUNCTIONS=['_clang_Interpreter_SetValueNoAlloc']") set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -s EXPORTED_FUNCTIONS=['_clang_Interpreter_SetValueNoAlloc']")


Adding all essential flags

- `EXPORT_ALL=1` emcc/em++
- `-s LINKABLE=1 -Wl,--export-all` to wasm-ld
- `"-Wl,--whole-archive" clangInterpreter "-Wl,--no-whole-archive"` ( As suggested [on emscripten's github](https://github.com/emscripten-core/emscripten/issues/22730#issuecomment-2412527423) .. this would force all object files in the library to be included)
- `set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -s EXPORTED_FUNCTIONS=['_clang_Interpreter_SetValueNoAlloc']")`

This won't be of any use as such because `LINKABLE` and `--export-all` would overwrite it

em++: warning: EXPORTED_FUNCTIONS is not valid with LINKABLE set (normally due to SIDE_MODULE=1/MAIN_MODULE=1) since all functions are exported this mode. To export only a subset use SIDE_MODULE=2/MAIN_MODULE=2

3) **Build `xcpp.js` and `xcpp.wasm`**

- Can add the export all flags as follows

macro(xeus_cpp_set_kernel_options target_name)

Building xeus-cpp-lite still get us the following

Debugging using EMCC_DEBUG=1 emmake make -j16 install VERBOSE=1 shows me this (not pasting everything ... only what looks relevant) 1) I guess this shows symbols coming out libclangCppInterOp.so
