[GRASSLIST:7458] Re: ANOUNCEMENT: GRASS 6 Exension Manager

[Michael Barton]

Benjamin,

I tried your suggestion and got a bit further. However, now I have a
different error. Also, FWIW, the line in my reg_entries.c does not have a
complete path. That is,

#include <dirent.h>

Instead of

#include </usr/include/sys/dirent.h>

I can't see that this is making a difference, (I tried it both ways) but
can't say for sure.

Anyway, this is the new error:


cmb-powerbook:/downloads/gem-0.9 cmbarton$ make clean
rm -f *.o *.bak core *~ gem
cmb-powerbook:/downloads/gem-0.9 cmbarton$ make
gcc  -c at_exit_funcs.c -Wall
gcc  -c error.c -Wall
gcc  -c tools.c -Wall
gcc  -c reg_deps.c -Wall
gcc  -c reg_entries.c -Wall
gcc  -c reg_html.c -Wall
gcc  -c actions.c -Wall
gcc  -c main.c -Wall
gcc  at_exit_funcs.o error.o tools.o reg_deps.o reg_entries.o reg_html.o
actions.o main.o -o gem -Wall
ld: can't locate file for: -lcrt1.o
make: *** [default] Error 1
cmb-powerbook:/downloads/gem-0.9 cmbarton$

This seems different from the prior error, so I haven't tried adding the
#include <sys/types.h> line. (Also, given the different error, I'm not sure
what file I'd add it to).
