Using g++ as a linker

[Fugitif]

Hi !
I'm trying to compile a project using a generic rule that compiles a .cpp to
a .o . To get the resulting program, I try to do the following:
g++ obj1.o obj2.o obj3.o -o program

But it seems that the dependency between the .o cannot be resolved: I get
"undefined reference" errors.

I've read the FAQs, but all the linker error are linked with "virtual" or
mixing C/C++.

If you have any advice, please tell me. Don't hesitate to give me links to
other project doing similar things.

Thanks.

Julien

Hi Julien,

We would be happy to answer this question
if you would just post it to the gnu.g++.help newsgroup.

Not enough information, can you create a very small program that demonstrates the
problem. Most likely you haven't consistantly declared the "C" linkage etc...
