gcc compiling and linking problem

Hi all,

I am facing a problem in creating an executable.

My code compiles fine but while linking with a static library it says undefined reference to "fuctionname".
Where as instead of creating executable if i am creating a shared library of it then it works fine (i don’t know it will run fine or not, but compiling and creation of .so goes fine).

Could you help me out of this problem?

I have heard that shared libraries are permitted to have undefined references. Is it true?

Thanks in advance.

A .so doesn't require all symbols to be resolved, so I'd guess that it simply hides the actual problem until you try to RUN the application that links to the .so.

ok, thanks for sharing the information.
I will run the application and see the possible results.

Any other information will also be appreciable.

It would also help if you let us know what the symbol that is undefined is. One of your symbols, something from the C library, or... ?

It is from some third party library.
I am trying to resolve, i will update you once i am done.

So maybe you need to link your library with that third party library?

It is solved.

I was compiling my code with the library only. But there were few conditional comiplation in libarary code, which needs to be configure in a header file. When i compiled the library code with proper configuration then it worked fine.

By the way, thanks a lot matsp for nice informations!
