Multiple definition error during Firefox build
Hi,
I'm working on building firefox using my modified LLVM.
I used below ".mozconfig" file (to build) and if I try to build it, I got multiple definition errors.
Could you let me know what was wrong ?
- I thought it will be "-lstdc++" option.
- But I need "-lstdc++" options.
[".mozconfig" file]
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/testfirefox
mk_add_options MOZ_MAKE_FLAGS=-j8
export LLVM_HOME="/home/jeon41/hextype/HexType"
export CC="$LLVM_HOME/build/bin/clang"
export CXX="$LLVM_HOME/build/bin/clang++"
export CFLAGS="-fsanitize=testfirefox -lunwind -lstdc++ -lm"
export CXXFLAGS="-fsanitize=testfirefox -lunwind"
