Is it possible to add a shared library to a static library ?
 

I have created a new shared library "libshared.so" . There is a existing static library "libstatic.a" . I need to refer the new code of .so into the .a files.

The libstatic.a compiles fine after I add -I<path_of_the_files_shared.so> in its Makefile.

Now this static.a is referenced in a exe . To avoid any linker issues I added -L<path_of_shared.so> -lshared in the Makefile of the exe . But when I try to compile it I get linker issue , of undefined reference to the libstatic.a for the methods of .so .

Even the nm for libstatic.a gives "U" for the methods of .so

Now my question is :

1) Is it valid to have a shared library call in a static library?
2) How to get rid of this undefined reference error ?

Please help me solve this issue.

Thanks.

Hi -

1. You can add anything you want to a library ... including your grocery list, if you wanted.

2. You can mix'n'match shared and static references in your program: some symbols can be static, others can be dynamic.

3. By the same token, Yes: it's absolutely legal for a subroutine in a shared library to call a static reference (in which case the static reference will be included in your actual .so file). It's also legal for a subroutine in a static library to call a shared reference.

Thanks for confirming. So can you pls elaborate on how to get rid of the linking issue when building the exe ?
