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]
