Glags/Glog errors during compilation

[Swami]

I am trying to build CAFFE in gpu mode in Ubuntu 12.04 using gcc 4.6.3. Its agonising to see that the compilation halts at the shown point.

************************************************************************************************************************

Its especially annoying because I know that the the glog/gflags headers and libraries were already used before in the compilation, I found lines like these:

************************************************************************************************************************

/homes/swamiviv/packages_local/glog-0.3.3/src/glog/logging.h(348): warning: using-declaration ignored -- it refers to the current namespace

/homes/swamiviv/packages_local/glog-0.3.3/src/glog/logging.h(352): warning: using-declaration ignored -- it refers to the current namespace

/homes/swamiviv/packages_local/glog-0.3.3/src/glog/logging.h(348): warning: using-declaration ignored -- it refers to the current namespace

************************************************************************************************************************

I should say that I do not have root access in the machine and hence I have installed glogd and gflags to a local dir and I changed the cmake config. parameters to reflect that, using the GLOG_INCLUDE(LIB)_DIR  and GFLAGS_INCLUDE(LIB)_DIR flags.

Can anyone see what's going wrong here or has anyone experienced this problem in their compilation?

Did you find a solution to this?

[X.T. Li]

Where did you install your glogs and gflags? You might need to use

export LD_LIBRARY_PATH=/path/to/libglog.so

to tell caffe where to find your gflags or glogs. For me, all these libs are in /usr/local/lib.

I solved it. In my case the LD_LIBRARY_PATH was set correctly but yet I was getting this error.

I set

export CPLUS_INCLUDE_PATH=$CPLUS_INCLUDE_PATH:/pkgs/gflags/include:/pkgs/glog-0.3.3/include:/usr/include/python2.7

and the header files started getting included. This was a bit unexpected as the lib files should have done that automatically.

Thanks though

Sorry for digging out this old topic.

I'm having a similar problem:

./include/caffe/common.hpp:6:26: Warning: glog/logging.h: file or directory not found 

In my system, glog is in /usr/local/ (so libglog.so is in /usr/local/glog/lib/).

Do I have to set in my .bash_profile 

export LD_LIBRARY_PATH=/usr/local

?

Or what do I have to add to avoid this warning/error?

[BlueRayONE]

I could finally handle it:

In the Makefile.config I extended INCLUDE_DIRS to "/usr/local/glog/include/" and LIBRARY_DIRS to "/usr/local/glog/lib". 

Hope that helps others, too.
