error: `GL_TEXTURE0_ARB' was not declared in this scope

[theprogrammer12]

Ich will mein OpenGL Programm mit dem MinGW kompilieren aber ich bekomme folgende Fehler:

make: Entering directory `/d/Eigene Dateien/cpp/gl/tloader'
-----------------------------------------------------------------------

So sieht die Makefile aus:

OBJ := main.o mesh.o shader.o texture.o vector.o vector2.o
MINGW_BIN := "D:\lib\MinGW\bin\g++.exe" 
OUTPUT_BIN := "tloader.exe"
MAKEFLAGS += -swr

start: $(OBJ)

	@echo "compiling $< ..."
	$(MINGW_BIN) -ID:\lib\MinGW\include -LD:\lib\MinGW\lib -lSDL -lSDL_image -lgl32 -lglu32 -Wall -c -o $@ $<

clean:
	@rm -fv *.o

distclean: clean
	@rm -fv $(OUTPUT_BIN)

und so die beiden Dateien, die der Fehler betrifft:

vector.h:

#endif

EDIT:
Auf Ubuntu läuft der Code einwandfrei! Muss also am MinGW liegen!

[pumuckl]

du hast im vector.h vergessen die nötigen Dateien zu #includen, in denen GL_TEXTURE0_ARB usw. definiert werden.

[Ein ehemaliger Benutzer]

Die <GL/GL.h> die mit Windows kommt bzw der SDK enthält leider nur die Defintionen bis OpenGL1.4 und kaum Extensions. Verwende daher am besten glew um die alle Extensions zur Verfügung zu haben. Erspart Dir auch das umständliche laden der Funktionen aus der Treiber-DLL.

Danke! Werd ich gleich mal testen.

ok. Die Fehler sind weg. aber dafür kommen gleich die nächsten:
