[GRASS-user] Spectral Unmixing

[Mohammed Rashad]

Hi Thomas,
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.

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.

The error he said about __g77_integer is mentioned here
https://bugs.launchpad.net/ubuntu/+source/gcc-3.4/+bug/61623
which says gcc-3.4
