GNU linker: alternative to --version-script to list exported symbols at the command line ?
- by David Cournapeau
On Linux with the GNU toolchain, I know how to control exported symbols from a shared library with a version script (gcc -Wl,--version-script=symbols.map), but I would like to list exported symbols on the command line instead. IOW, I would like the equivalent of
link /EXPORT:foo
from the MS toolchain. Is it possible ?
EDIT:
My question may not be very clearn: if I have a library libfoo.so, and I want to only export libraries foo1 and foo2, I can go create a version script foo.linux as follows
libfoo.so
{
global:
foo1;
foo2;
local:
*;
}
And do
gcc -shared foo.c -Wl,--version-script=foo.linux -o libfoo.so -soname libfoo.so
I would like to be able to do something like this instead:
gcc -shared foo.c -Wl,--export-symbol=foo1 -Wl,--export-symbol=foo2 -o libfoo.so -soname libfoo.so
