Hello all,
I'm moving a project from static makefiles to using
autoconf/automake/libtool. Everything is working great except for one
thing.
I need the ability to limit the dynamic symbols of a shared lib.
The method (on Linux) I was using before was this:
gcc -g -uR -shared -Xlinker --version-script -Xlinker foo.mapfile -o
foo.so foo.o
I've tried this but it only limits the 'normal' symbols:
libfoo_la_LDFLAGS = -module -export-symbols foo.sym
nm --dynamic libfoo.so
still shows all the symbols and my program doesn't behave.
I have a system in which I dlopen a number of libs that all derive from
a common C++ base class. This base class contains a few static
variables and functions that should be static to the lib not the whole
program.
The motivation for moving to autoconf/make was to have a generic build
system for a project that currently needs to build on Linux and
Solairs. I would like any solution to be generic across at least these
2 OSs.
Something like;
-export-dynamic-symbols SYMFILE
is what I'm looking for.
Can anyone point me in the right direction.
Thanks,
Allen
