Thank you very much for your help, Subbu. So now I ran exactly your two commands, but first, the build failed because it was missing `clang`. Do I assume correctly that the following dependency should be mentioned anywhere in the repository?
```sh sudo apt-get -y install clang ```
However, after installing clang and trying again, the build still fails.
The output contains the following errors:
- ``` error: unknown warning option '-Wno-unused-but-set-variable'; did you mean '-Wno-unused-const-variable'? [-Werror,-Wunknown-warning-option] ``` - ``` /mnt/c/Users/Christoph/OneDrive/Dokumente/Squeak/Christoph/git/opensmalltalk-vm/platforms/Cross/plugins/B3DAcceleratorPlugin/B3DAcceleratorPlugin.h:14:13: fatal error: /mnt/c/Users/Christoph/OneDrive/Dokumente/Squeak/Christoph/git/opensmalltalk-vm/platforms/Cross/plugins/B3DAcceleratorPlugin/B3DAcceleratorPlugin.h:14:13: fatal error: 'GL/gl.h' file not found # include <GL/gl.h> ^~~~~~~~~ 1 error generated. Makefile:179: recipe for target 'B3DAcceleratorPlugin.lo' failed make[1]: *** [B3DAcceleratorPlugin.lo] Error 1 Makefile:543: recipe for target 'B3DAcceleratorPlugin.la' failed make: *** [B3DAcceleratorPlugin.la] Error 2 ``` - Additionally, I am getting a large number of 177 warnings, which are probably not so important?
Could you tell me where I can get the `gl.h` header?
