I got binary GRASS6 installed on my laptop (Win10) . Now I am trying to use g.extension to compile r.prominence add-on but it failed. Below is the error info , can anyone give me some hints?

gcc -I/c/osgeo4w/usr/src/grass64/dist.i686-pc-mingw32/include -I/c/OSGeo4W/apps/gdal-16/include -I/c/OSGeo4W/include -g -O2  -I/c/OSGeo4W/apps/gdal-16/include -I/c/OSGeo4W/include  -I../dst/include    -DPACKAGE=\""grassmods"\"  -I/c/osgeo4w/usr/src/grass64/dist.i686-pc-mingw32/include -o OBJ.i686-pc-mingw32/main.o -c main.c

gcc.exe: installation problem, cannot exec `cc1': No such file or directory

make: *** [OBJ.i686-pc-mingw32/main.o] Error 1 ERROR: Compilation failed, sorry. Please check above error messages. rm: cannot remove directory `C:/Users/Zac/Documents/GIS DataBase/demolocation/PERMANENT/.tmp/2840.0/r.prominence': Permission denied

  • GRASS6 ?? In any case, from the error message, it seems you have a problem with your mingw32 installation. Also, why mingw 32 bit?? Is your win10 32 bit??

  • Please consider to update to GRAS GIS 7 or later

FWIW, I have updated r.prominence from GRASS GIS 6 version to 7 in https://github.com/OSGeo/grass-addons/pull/574. The changes are currently under review.
