Re: dlcompat and leading underscores on functions

[sending to list again, used the wrong e-mail address before - apologies list maintainer]

I asked myself that question, and decided the packages need to be more aware of cross platform issues rather than fixing it in dlsym. You can check if leading underscores are required in configure and prepend it in the dlsym calls if needed. Also write to the package authors/maintainers and tell them to include your patch to fix these issues.

See the configure check in glib for an example of how to do it. Okay, don't I'll append some code from it :)

There is no linker switch that I am aware of, and dlsym does not prepend the underscore. It would be easy for dlsym to do this, but I don't think it should.

From configure.in in glib:

         int glib_underscore_test (void) { return 42; }
		int main() {
		  void *f1 = (void*)0, *f2 = (void*)0, *handle;
		  handle = dlopen ((void*)0, 0);
		  if (handle) {
		    f1 = dlsym (handle, "glib_underscore_test");
		    f2 = dlsym (handle, "_glib_underscore_test");
		  } return (!f2 || f1);
		}

Is there a compiler/linker switch that can suppress the leading underscore
on exported function names in a bundle ?
or
Should dlcompat's dlsym() really prepend the underscore ?
