mex不兼容

编译sparsenet的时候报错

/Applications/MATLAB_R2010b.app/bin//mex: line 305: gcc-4.0: command not found 

一查 http://www.mathworks.com/matlabcentral/newsreader/view_thread/304310

好像是说对10.7系统的不支持，不过改下~/.matlab/...下面的mexopts.sh就行了

CC=gcc-4.0

>>CC=gcc
SDKROOT='/Developer/SDKs/MacOSX10.5.sdk'

>>SDKROOT='/Developer/SDKs/MacOSX10.7.sdk'
MACOSX_DEPLOYMENT_TARGET='10.5'

>>

MACOSX_DEPLOYMENT_TARGET='10.7'
