[GRASS-dev] pj_transform problem: failed to load NAD27-83 correction file

[Yann Chemin]

Hi list,

I am trying to make a program writing a latitude map. it works in a
lat/lon projection, but the only non-ll mapset i have is Spearfish,
and when testing on it, it returned this:

pj_transform() failed
cause: failed to load NAD27-83 correction file

GRASS_INFO_ERROR(19542,1): Error in pj_do_proj

How can i get through this problem? is it a problem in compilation of proj?
thanks,
Yann
