Working through a simple example. I tried the cdecl option but
for some reason i can compile but when i run my Gethello it
cant find the shared library in the same folder?

The binary's directory is not on the system search path by

Now I'm wishing that was the problem. Interestingly enough when i
link to a C shared library it works... but also it isn't show in
the needed shared library sections like below.
