It is widely used across platforms. It's nothing wrong for the developers to insist it's the default. Even on platform doesn't use the GNU linker by default like FreeBSD, it's easily installed from ports/packages and it will just work. It is you, a weirded platform, with it incompatible linker, that caused the problem. As I said many times before and being hated because of this but I will not afraid said it again: software developers will just skip your platforms and support other platforms that they will have the least effort to support, that is platforms that behave almost identical to their first class platform, usually be Linux. Perhaps you didn't read my last email. OK, it's too long, I myself tired to read it, too. I did try to remove --export-dynamic and after that I could have the compiler to generate a shared library (.so file). And you are right, trial and error is the only solution, because I have no one to mentor, no one to ask for. But unfortunately, it seemed the produced shared library doesn't work. The program linked with it will just sit there but do nothing, it doesn't even seem to be launched, indicating that it failed to load the shared library or the shared library simply doesn't work. Someone on the internet said I should run truss on the binary, I did and I found after a while the program just sit there idle. No outputs were even printed by this program to the terminal. It just stuck and needs to be canceled with Ctrl+C.
