Make caffe error

[BeSlower]

At first time when I make caffe, everything is good. Today when I try to make it again ( I did make clean before make), it shows following error.

I cannot figure out the reason. Could you give me some suggestions? Thanks.

It seems that some implementations cannot be found. For example, caffe::GlobalFinalize() should be implemented in src/caffe/common.cpp at here. Could you please check if this file is exactly the same as yours?

[BeSlower]

I checked src/caffe/common.cpp. It is exactly same as yours. Since I use git clone from yours, it shouldn't be different at all.

Hi there, I just came across this issue a few days ago. In my case, it is introduced by the libcaffe.so libcaffe.a linking error. This is because my server has been installed another version of caffe in the library path. And the Makefile finds the package from the system library path first and then the build library path.

You may try whether the change of the Makefile as below to solve the problem.

change the:
LIBRARY_DIRS += $(LIB_BUILD_DIR)
to:
LIBRARY_DIRS := $(LIB_BUILD_DIR) + $(LIBRARY_DIRS)

Hope it helps.
