[GRASS-dev] GRASS 6 swig compile error

[Markus Neteler]

Hi,

after the recent update I can no longer compile the GRASS 6 SWIG interface
(one bug just fixed, now got this):

make

Apparently GMATHlib isn't found? (it is compiled)
Ah, or in 7 the headers are in
 grass70/include/gmath.h
while in 6 they are in
 grass6/include/gisdefs.h

Swig seems to get that wrong... need to move the declarations?

thanks
Markus
