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
