- Subject: Limiting the exported symols in a shared library
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
