Hi Uday,
How are you building your so file? Are you including libprotobuf in the process?

Andreas,
Is there a way I can disable usage of protoc?
I’m using RHEL machine, so one thing I can try is to install protobuf-devel
package too.

Hi Andreas,
Yeah, I compiled and ran gem5.opt w/ hello_world successfully.
But, <gem5>.so still complains of the undefined symbol
_ZNK6google8protobuf7Message11GetTypeNameEv.

Hi Uday,
I don't dare say what's going wrong in the last linking step, but in terms of
the gem5 warning, you should be fine with the steps you mention. If you compile
gem5 as an executable, does it work fine?
There have been other reports of protobuf 2.5.0 causing some issues, but that
could be completely unrelated.

Subject: [gem5-users] protoc dependency
Hi,
I get the following error upon trying to build gem5:
Warning: Protocol buffer compiler (protoc) not found.
Please install protobuf-compiler for tracing support.
I have compiled and installed protobuf, how do I indicate it to gem5 build
system?
I have tried:
1. Setting environment PROTOC to /<some_path>/protobuf-2.5.0/install/bin
2. Setting environment PKG_CONFIG_PATH to /<some_ path
>/protobuf-2.5.0/install/lib/pkgconfig
Build completes, but when I collect *.o into a <gem5.so> link it w/ an
executable, I get this error:
undefined symbol: _ZNK6google8protobuf7Message11GetTypeNameEv
I assume this arises because of the warning while gem5 build. How can I resolve
this?
Thanks,
Uday
