llvm dev - Feb 2016 - [Firefox] How to compile firefox with Clang for Linux

Hi All,

I am trying to build firefox with clang in Ubuntu 14.04 64bit. There is
always configure failed errors problem. I follow compiling firefox with
clang on linux
<https://developer.mozilla.org/en-US/docs/Compiling_Firefox_With_Clang_On_Linux>.
I add "export CC=clang export CXX=clang++" to mozconfig file.

I wonder whether you guys have built firefox with clang in Linux. Could you
give me some tips how to build the firefox with clang.


Best Regards,
Pengfei

Hi Pengfei,

I'm pretty sure that some of the Mozilla devs are building Firefox with
clang on Linux. You'll get better (as in firefox-specific) advice at the
Mozilla's IRC channels (https://wiki.mozilla.org/IRC) given that the errors
happen during configuration-time.

Hi Vasileios,

Thanks for your suggestion. I will go to Mozilla's IRC channels to ask for
help.

My errors are as following:
