error: when build tools/extract_features.bin

I get following errors while trying to build on Ubuntu 14.04:

This problem seems like #757, but I don't know how to get ride of the error. Where things go wrong?
Thanks.

Ask installation questions on the caffe-users mailing list please!

Some versions of Anaconda seem to come with a bad libm. rm ~/anaconda/lib/libm.* takes care of this by reverting to the system libm.

[alexbw]

Also would be good to have on the installation page http://caffe.berkeleyvision.org/installation.html

[dywangshsf]

Thx shelhamer. After removing the libm files of Anaconda, my problem is solved.

Thanks @shelhamer, this is really helpful.
I get the same error, after I remove libm.* files, I succesfully compiled it.

Thanks alot

[bearpaw]

This also fixed my problem. Thanks!

[luyifan]

It fixed my problem

[as133]

Fixed my problem too. (I fixed by commenting the PYTHON_LIB in Makefile.config - I had added path to anaconda libs while building the python wrapper!)

+1 for adding to installation page.

[xucong-zhang]

fixed my problem too!

[prasttika]

also fixed my problem by commenting the PYTHON_LIB in Makefile.config - thanks

I am facing same sort of error while installing caffe with Anaconda.
