Help! Newbie problem

[Jeff Sciortino]

When I try to compile hello world form K&R I get the error:

bash-2.01$ gcc hello.c
/usr/lib/crt1.o: In function `_start':
/usr/lib/crt1.o(.text+0x36): undefined reference to `main'
collect2: ld returned 1 exit status

I'm running 2.95.2 on debian 2.1. I didn't build gcc on my machine, I
downloaded the debs and installed it.

I _think_ I installed all the requisite libraries, do I need an
environment variable that I'm missing?

I've also tried to compile a sample objective C program, and got the
following errors:

/tmp/ccNO7eLj.o: In function `main':
/tmp/ccNO7eLj.o(.text+0x28): undefined reference to `objc_get_class'

Thanks much for any light anyone can shed.

If you need more info to get a better handle on it, let me know.

Regards,
