Hello,
I try to build latest gem5 master branch from github but get the error below
with protobuf
In file included from build/X86/cpu/o3/probe/elastic_trace.hh:61:0,
from build/X86/cpu/o3/probe/elastic_trace.cc:42:
build/X86/proto/inst_dep_record.pb.h:453:6: error:

#if !PROTOBUF_INLINE_NOT_IN_HEADERS

cc1plus: all warnings being treated as errors
scons: *** [build/X86/cpu/o3/probe/elastic_trace.o] Error 1

Trying to fix the above with a change like below
https://github.com/SanchayanMaity/gem5/commit/a8cf9e1fc6e840e83721b41b1a7ac6badeccef43
which I found in some earlier post on gem5 ML, then gives me the following error

I use Arch Linux with gcc 6.3.1 with below protobuf libs installed
libprotobuf-c.so
libprotobuf-c.so.1
libprotobuf-c.so.1.0.0
libprotobuf-lite.so
libprotobuf-lite.so.11
libprotobuf-lite.so.11.0.0
libprotobuf.so
libprotobuf.so.11
libprotobuf.so.11.0.0
While I have a working gem5 branch which has top commit as
commit 1738a7d2601ba757ae6ab36f0549a50396d73e45
Author: Andreas Sandberg <[email protected]>
Date: Tue Jan 3 17:31:39 2017 +0000
sim: Remove declaration of unused CountedDrainEvent
and then the patch to fix build issue on Arch Linux I shared
earlier.
So this is not a critical issue for me but I did like to know if
someone else faced the same issue and if there is a known simple
fix to this.
Thanks for your help and listening.
Regards,
Sanchayan.
