Question g++ compiler

Hello
I use kDevelop to compile my GLUT source codes.But i dont like to make all those projects with all those files.I want to compile my GLUT using g++.
In my linker options from my kDevelop i click on the libraries: X11, Xext and Math.

Then i add -lglut -lGLU -lGL -lXi -lXmu to Additional Libraries.

So what do i need to type on a shell to compile my GLUT c plus plus file?
thanx Hylke

my guess would be

Code:
g++ -o myprog myprog.cpp -L/usr/X11R6/lib -lglut -lGLU -lGL -lXi -lXmu -lX11 -lXext -lm
This should really be put into a Makefile, assuming that it works at all -- like I said, it's a guess

btw, you might try -lMath instead of -lm

What do u mean with putting it in a makefile?
I typed g++ -o myprog myprog.cpp -L/usr/X11R6/lib -lglut -lGLU -lGL -lXi -lXmu -lX11 -lXext -lm and g++ -o myprog myprog.cpp -L/usr/X11R6/lib -lglut -lGLU -lGL -lXi -lXmu -lX11 -lXext -lMath in a command line but both didn't work.

Maybe you could define "didn't work" a little bit better. Like with actual error output. We can't very well tell you how to fix it if you don't tell us what error you got.

Edit: Also, you should read up on Makefiles a bit. They will make your life easier. Do a Google search, and I bet you will find tons of information explaining them.

It appears you aren't including the source for your GameEngine class. Is that in main.cpp, or a separate .cpp file? If it's in a separate .cpp file, you will have to include that in your list like so:

g++ -o myprog main.cpp GameEngine.cpp -L/usr/X11R6/lib -lglut -lGLU -lGL -lXi -lXmu -lX11 -lXext -lm

I gues that's just the same.

GameEngine.h shouldn't go on the command line; it should be #included by whatever file needs it, which it looks like it is. You need to check that GameEngine.h exists and is in the directory with GameEngine.cpp.

I found this in a file of my directory where i compile the source code using kDevelop.

PHP Code:
####### kdevelop will overwrite this part!!! (begin)##########
bin_PROGRAMS = testgameengine

## INCLUDES were found outside kdevelop specific part

testgameengine_SOURCES = main.cpp GameEngine.cpp 
testgameengine_LDADD   = -lglut -lGLU -lGL -lXi -lXmu -lm -lXext -lX11


EXTRA_DIST = GameEngine.cpp GameEngine.h main.cpp 

####### kdevelop will overwrite this part!!! (end)############
# set the include path found by configure
INCLUDES= $(all_includes)
 
# the library search path.
testgameengine_LDFLAGS = $(all_libraries)

looks like kDevelop uses automake. probably it would be a good idea to continue using that.

anyway, are you including GameEngine.h like #include <GameEngine.h> or like #include "GameEngine.h" ? It should be done the second way. I'm not entirely sure if that would cause the problem but it might.

I dunno what to tell you except that the compiler doesn't see a GameEngine.h in that directory

I wanted to put my GameEngine.h in my GameEngine.cpp and then i saw that i had used <'s instead of "s.
Thank you for your help.
Hylke

EDIT: I have another question:
I want to use texturing but then i need to add the glaux library.But how do i add the glaux library?
thanx again.

I'm going to guess that you give -lglaux on the gcc line, and #include some header to use it, perhaps glaux.h. Not having glaux, I can't really know
