| A very common question that keeps appearing on the list is "why do I get linker errors using VC++", the reason being that winsock libraries and/or common control libraries (for trackmousepopup) aren't linked.
It can be solved by adding
#pragma comment(lib,"wsock32")
#pragma comment(lib,"comctl32")
In which case the VC linker will automatically add the required libraries during linkage.
It would probably be a good idea to only include the pragma if relevant code is used (e.g., under the same #ifdef that makes use of select() or TrackMouse()), and also make it possible to turn off through some definition in config.h, in case it causes trouble for anyone. | |

| This is a common request. Unfortunately, the pragmas are not portable to different WIN32 compilers, so I don't know if we will incorporate them.
If we do, it won't be until FLTK 2.0, as 1.1.x is in a feature freeze. | |

| This is actually pretty good idea, and can help beginners when starting with C++ & FLTK & VC++ . | |

| Hi Dejan,
I suggest that you put that in FL_API.h as it concerns linking code generation and furthermore it's included everywhere ...
So we could add just after the ifdef clause of FL_API.h :
#if _MSC_VER >1000
# pragma once
# pragma comment(lib,"wsock32")
# pragma comment(lib,"comctl32")
#endif
This way we are we won't hurt other builds type | |
