Hi Thomas,<div>I had ported spectral unmixing to grass7. Myself and Markus had tested it several times on both G6 and G7 and updated it every time.</div><div><br></div><div>The problem is because of g2c.h which is not used by gcc4+. and g2c.h headers are included in lapack wrap code of gmath lib.</div>

<br>
there was recently some question about spectral unmixing here in the list.<br>
<br>
If you didn't modify the source code of the unmixing model to fit Grass 7 it won't work. Spectral unmixing was written by Markus as part of his diploma thesis, is now some years old and is based on Grass 5.something, if I'm not wrong.<br>
<br>
Would be great if you can get it to work in Grass 7.x! Seems to me there is quite some interest in this module.<br>
