<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: Anutosh Bhat (anutosh491) <details> <summary>Changes</summary> While building llvm (clang, lld) for wasm using emscripten (recipe hosted on emscripten-forge https://github.com/emscripten-forge/recipes/tree/main/recipes/recipes_emscripten/llvm) I ended up with this error ``` │ │ wasm-ld: error: ../../../../lib/libclangInterpreter.a(Wasm.cpp.o): undefined symbol: lld::wasm::link(llvm::ArrayRef<char const*>, llvm::raw_ostream&, llvm: │ │ :raw_ostream&, bool, bool) ``` This is due to the link function here https://github.com/llvm/llvm-project/blob/a4819bd46d8baebc3aaa8b38f78065de33593199/clang/lib/Interpreter/Wasm.cpp#L25-L30 This was added through this PR (https://github.com/llvm/llvm-project/pull/86402) as an attempt to support running clang-repl and executing C++ code interactively inside a Javascript engine using WebAssembly when built with Emscripten. The definition for link is present in lldwasm and when building for the emscripten platform we should be linking against it. --- Full diff: https://github.com/llvm/llvm-project/pull/113446.diff 1 Files Affected: - (modified) clang/lib/Interpreter/CMakeLists.txt (+2) ``````````diff diff --git a/clang/lib/Interpreter/CMakeLists.txt b/clang/lib/Interpreter/CMakeLists.txt index 2cc7c59b61d318..d5ffe78251d253 100644 --- a/clang/lib/Interpreter/CMakeLists.txt +++ b/clang/lib/Interpreter/CMakeLists.txt @@ -14,6 +14,7 @@ set(LLVM_LINK_COMPONENTS if (EMSCRIPTEN AND "lld" IN_LIST LLVM_ENABLE_PROJECTS) set(WASM_SRC Wasm.cpp) + set(WASM_LINK lldWasm) endif() add_clang_library(clangInterpreter @@ -44,6 +45,7 @@ add_clang_library(clangInterpreter clangParse clangSema clangSerialization + ${WASM_LINK} ) if ((MINGW OR CYGWIN) AND BUILD_SHARED_LIBS) `````````` </details> https://github.com/llvm/llvm-project/pull/113446 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
