This works! Thanks, Peter.
f95 -c hello.f90
gcc -v -o hello -nostdlib \
/usr/lib/crt1.o /usr/lib/crti.o /usr/lib/crtbegin.o \
/usr/local/lib/NAGWare/quickfit.o hello.o /usr/local/lib/NAGWare/libf96.so\
-lm \
/usr/home/karg/tmp/minpack/lib/libc.so \
/usr/lib/crtend.o /usr/lib/crtn.o
But, the 2nd and 6th lines in the gcc command use the crt* files
from freebsd-current. The math library, -lm, is also from
freebsd-current. /usr/lib/compat does not contains neither
a 4.x math library nor the crt* files. The libc.so is the
symlink you suggested.
kargl[274] ldd hello
hello:
libf96.so.1 => /usr/local/lib/NAGWare/libf96.so.1 (0x2806b000)
libm.so.2 => /usr/lib/libm.so.2 (0x2810b000)
libc.so.4 => /usr/lib/compat/libc.so.4 (0x28129000)
