I am trying to build following the steps mentioned in INSTALL.md.

Environment: MacOS 10.14.2
Gcc Version:

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/include/c++/4.2.1
Apple LLVM version 10.0.0 (clang-1000.10.44.4)
Target: x86_64-apple-darwin18.2.0
Thread model: posix 

Error Log:

Hi,

looks like your GCC version is 4.2? You might need to update it to use a newer GCC.

Check the warning that you got

                               !! WARNING !!

Also, check https://github.com/facebookresearch/maskrcnn-benchmark/blob/master/TROUBLESHOOTING.md#compilation-errors-when-compiling-the-library , this might have the information there that you are looking for in order to fix your compilation issue

@tanmaybinaykiya Hi，I met the same ,you sloved it?

[fmassa]

This error is due to a wrong gcc version, as mentioned in the previous issue.
Closing this as the solution has already been posted.
