[gem5-users] Build Error

[Shashwat Gupta]

Hey,

I’m trying to build gem5 on my mac using:
scons build/ARM/gem5.opt

Details:
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

Target: x86_64-apple-darwin18.0.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

and getting the following errors:
