WXTide32 and svHorizon forum

Hello,

I have loaded the source code (from wxtid47.zip) on lcc-win32, to compile it.
(I chose lcc since this was the platform it was developed on.)

I get a small but decisively blocking error in the compilation:
(I have made absolutely no changes to the original code.)

lcc output follows:

Code: Select all

Compilation + link time:0.4 sec, Return code: 10

I'm referring to the undefined reference errors. In the header files, I can find defined "fabsf" and "_fabsi" (one underscore less).
Apparently the compiler prepends an extra underscore to these names, and then cannot find them to make the link.

If it's any help, Line 3841 is this:

Code: Select all

if (GetDlgItemFloat(hwnd, IDF_MARKLEV, &tmpFloat) &&
                !FSAME(tmpFloat, pSection->marklev))

Any help with this would be greatly appreciated!
Thanks in advance,
Ioannis

It appears that error must be caused by the FSAME macro but I haven't a clue why. I recently had a hard disk crash and will be rebuilding things using more up-to-date tools and Windows 7 so I should be able to find out what is causing that problem.

The FSAME macro is pretty simple, it looks like:

Code: Select all

#define FSAME(a,b) (fabs(a-b) < 0.0001)
