AllegroFont and MSVC

Hello!

This is driving me crazy, I've compiled (v2.0.6) AllegroFont both static and DLL but I cant use either one without problems

Using the DLL version of the .lib I can compile my little test, run it untill I use:

alfont_destroy_font(Font);

MSVC pops up with

Quote:

"Unhandled exception at 0xSOMEHEX in alfont_text.exe: User breakpoint."

What breakpoint???
Then I press continue and all is fine, but damn so annoying.

If I use the static .lib I cant even compile my test. Instead MSVC says

Quote:

alfont_test error LNK2019: unresolved external symbol _ugetc referenced in function _alfont_ugetc
alfont_test error LNK2005: _clear_to_color already defined in alld.lib(alld42.dll)
alfont_test warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library
alfont_test error LNK2019: unresolved external symbol _ugetxc referenced in function _alfont_text_length

Any ideas?

~~-EDIT~~-
Here's my minimal test

1#include 
2#include "alfont.h"
3 
4int main(void)
5{
BITMAP *buffer;
ALFONT_FONT *Font;
if (allegro_init() != 0) return false;
    install_keyboard();
    set_color_depth(32);
    if (set_gfx_mode(GFX_AUTODETECT_WINDOWED, 640, 400, 0, 0) != 0) {
  allegro_message("Unable to set any graphic mode\n%s\n", allegro_error);
        return false;
    }
if (alfont_init() != ALFONT_OK) {
  set_gfx_mode(GFX_TEXT, 0, 0, 0, 0);
  allegro_message("Error while initializing alfont");
  return false;
}
    buffer = create_bitmap(SCREEN_W,SCREEN_H);
    set_palette(desktop_palette);
22 
Font = alfont_load_font("fonts/phorfeir.ttf");
alfont_set_font_size(Font,30);
25 
    alfont_textout(screen, Font, "asdf", 30, 30, makecol(255,255,255));
while(!key[KEY_ESC]) rest(1);
alfont_destroy_font(Font);
    alfont_exit();
    destroy_bitmap(buffer);
    return 0;
32 
33}
34END_OF_MAIN()

Have you tried it with a standard compiler instead of MSVC?

The problem is with the runtime library you are linking with. When linking a static library link against Multi-threaded (/MT). When making a DLL link against Multi-threaded DLL (/MD). When you compile your program make sure that all the libraries and the program itself use the same runtime library. Don't ask further questions, that's all I know.

Never thought of that because it does come with project files for MSVC, although for v6 and I'm using v7.1.
I got the feeling I cant make a MSVC compitable .lib with say, MINGW.

I've tried all the combinations I can, those that actually compile are the ones that give me the problems I described in the first post.

I guess, I'll have to live with FontEd and make some fuggly fonts without AA
