Re: a new user's question

I try to install gfortran 4.1 and use command
 gfortran-4.1 -fPIC -fno-second-underscore -fno-range-check -O -o cpex08
cpexcc.f cpex08.f -L/usr/local/lib -L/usr/lib -lncarg -lncarg_gks -lncarg_c
-lX11 -lXext -lpng -lz -lgfortran

However the information is:
/usr/lib/gcc/i486-linux-gnu/4.1.3/../../../../lib/crt1.o: In function
`_start':
(.text+0x18): undefined reference to `main'
collect2: ld 返回 1
It seems _gfortran_copy_string thing is due to the fortran version, but this
problem is ?
