Re: [scipion-users] Fwd: scipion-installer - how do i change compiler optimization flags?

[Carlos O. S. <co...@cn...>]

Dear Wolfgang,

in the compilation of Xmipp, you can set the environment variable 
CXXFLAGS before calling the xmipp script. From the Scipion installation 
I am not sure how to pass it to the xmipp script. It may be that setting 
it in the shell before calling scipion suffices. But I have never tried.

Kind regards, Carlos Oscar
