I took a git checkout of mongodb source files and am trying to compile it. I have gcc installed as part of xcode-7.3.1 command-line tools
Now when I am trying to build the mongodb binaries using:
scons all
I am getting the below error:
scons: Reading SConscript files ...
scons version: 2.5.0
python version: 2 7 10 'final' 0

See /Users/debashish.g/mongo-code/mongo/build/scons/config.log for details
In the config log it shows:

My gcc --version shows :

Which is clang. Where am I doing wrong? Please help. I am stuck on this for a long time now.
What I missed was clang and llvm tools . I took a checkout of the source files and did a build of the clang tools according to the steps mentioned here.
