[ENet-discuss] Linker errors when NOT compiling as a lib (embedded) [with suggested fix]

[Nicholas J Ingrassellino]

It is awesome that you posted this. Thank you. In this spirit I will 
post something I was struggling with.

I had an issue using ENet with Allegro with Visual C++ 9. The headers 
need to be:

    #define _WINSOCKAPI_
    #define ALLEGRO_STATICLINK
    #define ALLEGRO_NO_ASM

    #include <allegro.h>
    #include <winalleg.h>
    #include <enet/enet.h>

and the libs needs to be

    alleg_s_crt.lib kernel32.lib user32.lib gdi32.lib comdlg32.lib
    ole32.lib dinput.lib ddraw.lib dxguid.lib winmm.lib dsound.lib
    enet.lib ws2_32.lib

Any other order in the headers threw a mess of unresolved external 
symbols which took me a decent amount of time to figure out. As you can 
probably tell I am statically linking Allegro. This should also work 
with Allegro being dynamically linked (obviously with /#define 
ALLEGRO_STATICLINK/ removed).

solve it with the tools at hand, and wind up with a program that could 
not be legally used because someone else followed the same logical steps 
some years ago and filed for a patent on it is horrifying."
