Undefined symbols from ld? ; making bundle; gcc 3.3

I have been pulling my hair out trying to figure out this error when using ld

Code:

---

> gcc -fPIC -c edges.c
> gcc -fPIC -c bfunctions.c

> ld -bundle -t -o edges.so edges.o bfunctions.o

ld: Pass 1
edges.o
bfunctions.o
ld: Undefined symbols:
___sF
_atof
_fclose
_fopen
_fprintf
_memcpy
_perror
_printf
_strcat
dyld_stub_binding_helper

---

I have got all the right #include files in edges.c so those undefined symbols are looking mysterious.

I have done this process before, making a Mach-0 "bundle" but today it is coming up with these errors. Is there somewhere I should look -- source files? gcc options? -- to resolve this headache? Has it got to do with using more than one object file?

Gracias for the help.

Use gcc to call ld
It passes along a whole bunch of stuff (use -v to find out what)

I didn't find a -bundle in the help for ld - what exactly are you trying to do?

-bundle is the Mac OS-X flag to gcc that creates a shared library. It corresponds to /DLL on a Windows box and -shared on Linux.

does this help you

Code:

---

gcc -o (name of program)  *.o

I already know how to do that.

Try adding these flags then to your compile lines: "-Wall" and "-pedantic". Then remove your object files and recompile.

Quzah.
