[Mingw-cross-env-list] Undefined reference to freeglut library functions

[Son Hua]

Hi all,

I used mingw-cross-env on Ubuntu 10.10 to cross compile a simple OpenGL 
program (Lesson 03 of NeHe, 
http://nehe.gamedev.net/data/lessons/linux/lesson03.tar.gz).

MinGW compiled the program fine, but failed to link to functions in GLUT 
library, which is actually freeglut installed by mingw-cross-env using 
"make freeglut". I included my output here. To reproduce the error, 
please follow these steps.

1. Follow the tutorial on mingw-cross-env website to install mingw cross 
compile environment. I tried with both 2.17 and the development version. 
Install freeglut by "make freeglut".
2. Download a simple OpenGL program 
(http://nehe.gamedev.net/data/lessons/linux/lesson03.tar.gz) to test for 
cross compilation. Here uses lesson03 of NeHe.
3. Compile
i686-pc-mingw32-gcc -c lesson3.c
4. Link
i686-pc-mingw32-gcc -o lesson3.exe lesson3.o -lopengl32 -lglu32 -lglut

Step 1 - 3 works fine. Output of step 4:
lesson3.o:lesson3.c:(.text+0x1c): undefined reference to 
address@hidden'
lesson3.o:lesson3.c:(.text+0x3e): undefined reference to 
address@hidden'

address@hidden'
lesson3.o:lesson3.c:(.text+0x4e3): undefined reference to 
address@hidden'
collect2: ld returned 1 exit status

As far as I know, the opengl32, glu32, glut library is found by 
examining relative path from i686-pc-mingw32-gcc to find the "lib" 
folder, so the library path should not be a problem here.

I also notice similar undefined reference with functions in FreeImage 
library. Am I doing anything wrong here? Note that the program compiles 
well using gcc on Ubuntu. But it failed when using i686-pc-mingw32-gcc.

Thanks for your help.

Best regards,
Son.
