Not an error, a warning :) If you check, your app binary was probably
created in your build directory.
Here's my understanding:
I can't speak to whether you really need to, but you are passing
-static. According to the gcc manpage, this means "this prevents
linking with ... shared libraries".
This is a lie. gcc still does a dynamic link to libgcc, which is
assumed to be so widely available that it's a waste to statically
link it. But gcc is nice and warns you that your application is not
completely statically linked.
So you can try running your application on the target platform. If the
proper shared libs exist there, then you're good to go.
If not, you need to statically link libgcc as well at compile time. Do
that by passing -static-libgcc to your compiler.
Disclaimer: I'm not a guru in the area, so ymmv.
Good luck,
Eric
