Hi,
I'm having problems with visibility attributes and ld scripts. For instance,
the following program (test.c):
extern __attribute__((visibility("internal"))) void *__foo;
void* f(void) {
return __foo;
}
compiled with the following script (test.lds):
SECTIONS {
.data: {
__foo = .;
}
}
compiled with
gcc-4.0 test.c test.lds -o libtest.so -shared -fPIC
produces the following error:
/usr/bin/ld: /tmp/ccUpkjLi.o: relocation R_X86_64_PC32 against `__foo' can not
be used when making a shared object; recompile with -fPIC
This happens because __foo isn't defined as being internal in the linker
script. Is there a way to do this? (I couldn't find in the info pages).
