Subject: Limiting the exported symols in a shared library
Date: Fri, 11 Oct 2002 12:14:00 -0000	[thread overview]
Message-ID: <B9CC718C.2509%Barry.Leslie@shaw.ca> (raw)

Hi,

I want to create a shared lib and limit the symbols exported from it to the
functions specified in an api list. I don't want all the global symbols to
be visible. 

On many platforms this is done simply by listing the symbols in a file and
then passing the file name in as a command line argument. For example on AIX
you use -bE:api.exports and on Sun you use -M api.exports.

What is the equivalent for the linker on Linux?

I tried --retain-symbols-file api.exports but all the global variables and
functions were still visible when I did a 'nm -g mylib.so'.

Can anybody help me out here?

Thanks,
    Barry
