[GRASS-user] Spectral Unmixing

[Mohammed Rashad]

what is your gcc version?

post output of gcc -v

gcc 4.x doesnt need g2c.h and HAVEG2C_H remains undefined.

if you are using gcc4.x i can provide you a patch for la.h which will solve
the issue for now.

Developers of gmath lib will have more comment on G2C issues
