Hi!
I'm tring to compile and after ./configure I get this:
/root/.bashrc UNIX_BIN=/usr/local/bin SCR=/usr/local/grass5.0beta
GISBASE=/usr/local/grass5.0beta MACHINENAME=grass.lv.parnu.ee /bin/bash
scr/CMD/generic/CREATE_GMAKE.sh
/bin/bash: /root/.bashrc: Permission denied
make: *** [pre-install] Error 126
What's up?
