我試圖用這個庫輸出文本在OpenGL應用程序到目前爲止，我得到了一個prcompiled庫，所以我上手所以它會更容易這樣的代碼：FTGL未定義的參考文獻？
#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;
}
所以，如果我不編譯它與該接頭：
-lmingw32 -lSDLmain -lSDL -lopengl32 -lglu32 -lSDL_image -lm -lgdi32 -lsdl_mixer -lSDL_ttf
我得到這個錯誤：
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 ===|
現在，這應該是因爲我忘了把接頭右IDK原因，如果我包括2 REM癌寧接頭：
-lfreetype2 -lftgl
我得到這樣的錯誤50 Im不去把它們放在這裏我不想打破你的眼睛的傢伙。
那麼可能是什麼問題我可以做什麼來解決這個問題？
IDE：代碼塊 操作系統：Windows

所以切換順序我仍然得到錯誤

最後更新
正確的順序是後：
-lmingw32 -lSDLmain -lSDL -lSDL_image -lm -lgdi32 -lsdl_mixer -lSDL_ttf -lftgl - lfreetype2 -lopengl32 -lglu32
你應該附上您鏈接到的'freetype2'因爲你已經理所當然地推導出後得到的錯誤第一組錯誤是鏈接錯誤，因爲您沒有鏈接到'freetype2' – 2012-01-03 15:06:07
您必須鏈接ftgl庫。如果使用-lftgl -lfreetype2而不是您使用的順序會發生什麼情況。如果不起作用，請輸出5行輸出。 – casualcoder 2012-01-03 15:08:58
parapura是對的。僅僅因爲第二組錯誤並不意味着它們不是你的_real_問題。 – 2012-01-03 15:32:40
