Dear friends,

I want to compile a c file called read_pgm.c
It has more than 4 library files:
matrix.c
matrix.h
strfun.c
strfun.h
uchar_matrix.c
uchar_matrix.h
pgmio.c
pgmio.h
color.h

I successfully compiled 4 files which are
matrix.c
strfun.c
uchar_matrix.c
pgmio.c

and when i try to compile read_pgm.c, with this command:
gcc -o read_pgm1 read_pgm.c pgmio.o -lm
./read_pgm1
result:
segmentation fault
and then,
sudo ./read_pgm1
result:
segmentation fault

It should ask me password, isn't it?
Any suggestion?

Thanks for your help...

Best Regards,

Ika
