   6 # Building gem5
   7
   8 Official instructions are sparse.  Under exploratory development:
   9
  10     apt-get install ccache build-essential scons libprotobuf-dev \
  11                     libpython2.7-dev protobuf-compiler
  12     scons -j16 build/POWER/gem5.opt
  13
  14 Two warnings are given about fallthrough on case statements... which are commented as such... and yet nobody thought to tell the compiler that.  TODO: investigate how to disable "-Werror" in scons...
  15
  16 # gcc powerpc cross-compiler
  17
  18 Note that this is not the same as the 64-bit powerpc64le or the 64-bit powerpc64 compiler
  19
  20     apt-get install gcc-8-powerpc-linux-gnu g++-8-powerpc-linux-gnu
  21
  22 # libtcmalloc
  23
  24 Apparently installing libtcmalloc gives a 12% performance increase
  25
  26     apt-get install libtcmalloc-minimal4
