Question

I was trying to use this library to output text on a OpenGL application so far I got a prcompiled library so it would be easier to me to get started so this the code:

#include <SDL/SDL_opengl.h>
#include <FTGL/ftgl.h>
...
...
int main( int argc, char* args[] )
{
...
...

//Y U NO WORK!
FTGLPixmapFont font("ariblk.ttf");
if(font.Error())

...
...

 SDL_Quit();

 return 0;
 }

So if I do compile it with this linkers:
-lmingw32 -lSDLmain -lSDL -lopengl32 -lglu32 -lSDL_image -lm -lgdi32 -lsdl_mixer
-lSDL_ttf

I get this errors:

OPENGL ETC\SDLOPENGL\main.cpp|108|undefined reference to `FTPixmapFont::FTPixmapFont(char const*)'|

OPENGL ETC\SDLOPENGL\main.cpp|109|undefined reference to `FTFont::Error() const'|

OPENGL ETC\SDLOPENGL\main.cpp|303|undefined reference to `FTPixmapFont::~FTPixmapFont()'|

OPENGL ETC\SDLOPENGL\main.cpp|303|undefined reference to `FTPixmapFont::~FTPixmapFont()'|
||=== Build finished: 4 errors, 0 warnings ===|

Now this should be cause I forgot to put linkers right IDK cause if I include the 2 remaining linkers:

-lfreetype2 -lftgl

I get like 50 of errors Im not going to put them here I dont want to broke your eyes guys.

So what could be the problem what can I do for fixing this?

IDE: CodeBlocks
OS: Windows

EDIT:

So after changing order I still get errors

Seems like it will not work thx guys for your answers now after doing what casualcoder said errors still

LAST UPDATE

The right order was:

-lmingw32 -lSDLmain -lSDL -lSDL_image -lm -lgdi32 -lsdl_mixer -lSDL_ttf -lftgl -lfreetype2 -lopengl32 -lglu32

Answer 1

Try moving -lopengl32 -lglu32 after -lftgl. Let us know what happens.

Look at this question for more details on your problem and how to solve it in future:

Why does the order in which libraries are linked sometimes cause errors in GCC?
