This changeset adds support for building with google protobuf. I think the
patch erroneously assumes that pkg-config will work correctly in all
situations. I got the following error while trying to build gem5 --
scons: Reading SConscript files ...
Package protobuf was not found in the pkg-config search path.
Perhaps you should add the directory containing `protobuf.pc'
to the PKG_CONFIG_PATH environment variable
No package 'protobuf' found
OSError: 'pkg-config --cflags --libs-only-L protobuf' exited 1:
File "/scratch/nilay/GEM5/gem5/SConstruct", line 646:
main.ParseConfig('pkg-config --cflags --libs-only-L protobuf')
File "/usr/lib/scons/SCons/Environment.py", line 1460:
return function(self, self.backtick(command))
File "/usr/lib/scons/SCons/Environment.py", line 593:
raise OSError("'%s' exited %d" % (command, status))
Please take a look at into this.
