I've been programming on DOS for a while, but I'm pretty new to the unix
side, "make" etc.
I'm on a BSDI 4.0 machine.
I'm trying to use GCC to compile PDFlib,
http://www.ifconnection.de/~tm/
I've #defined the POSIX variable that seems to be required for a UNIX
build.
I've done "ln -s makefile.gcc makefile" (seems okay)
and "make test"
This is the result:
gcc -o text2pdf libpdf.a -lm
/usr/lib/crt1.o: In function `__start':
/usr/lib/crt1.o(.text+0x78): undefined reference to `main'
*** Error code 1

I've looked at text2pdf.c, and it DOES have a reference to "main"
What could be wrong?
Help!

This is not specifying any source or object files, only libraries.
That probably means that something in the makefile is broken.

Ah, that makes more sense. Now it says
"make: don't know how to make text2pdf.o. Stop"
I guess I'll have to read up on makefiles now. Any suggestions where to look?

Err, just a thought: you may want to try using GNU make. The BSDI make
(is it pmake?) probably doesn't understand GNU make syntax, and will
hence do strange things such as you describe. You may already have it
installed as `gmake', otherwise download it from ftp.gnu.org or
(preferably) a mirror site.

Regards,
Nic.
