Hi,

I'm experiencing a strange error when I try to compile a file that
includes one other file located in the local directory (I'm including
the sources with this posting). Here's how I invoke the compiler and the
output I'm getting:

[C:/complex_test/complex/complexlib] gcc complex.C -o complexlib.a
c:/djgpp/lib\crt0.o(.data+0x92):crt0.s: undefined reference to `main'
c:/djgpp/lib/libc.a(crt1.o)(.text+0x312):crt1.c: undefined reference to
`main'

I also get the same message when I use gxx instead of gcc. I've tried
compiling from both the MS-DOS shell and from MKS Korn shell with the
same results. I'm running NT4.0 and have disabled LFN (lfn=n). Any help
would be greatly appreciated. Please cc my email.

Incidentally, I have successfully compiled and linked simple "hello
world" type programs.

Oh, here are are the sources:

Thanks in advance for any help.
