Compilation issues with Mono

[Erik Karlsson]

Hi,

I just starting to use Tao so I'm sorry if I'm asking question that is
well known.

I just checked out a copy from the SVN and started to build the
different parts of the Tao framework. However, I encountered an issues
when trying to compile the Tao.OpenGL.dll.

I was using the guidelines defines in the README.autotools. My
environment is mono + ubuntu 7.10 (x86).

When compiling the Tao.OpenGL I got the following errors:

./Glx.cs(923,50): error CS0626:
`Tao.Platform.X11.Glx.glXQueryExtension(System.IntPtr, int*, int*)' is
marked as an external but has no DllImport attribute. Consider adding
a DllImport attribute to specify the external implementation
./Glx.cs(991,50): error CS0626:
`Tao.Platform.X11.Glx.glXQueryVersion(System.IntPtr, int*, int*)' is
marked as an external but has no DllImport attribute. Consider adding
a DllImport attribute to specify the external implementation
./Glx.cs(1312,43): error CS0626:
`Tao.Platform.X11.Glx.glXQueryDrawable(System.IntPtr, System.IntPtr,
int, uint[])' is marked as an external but has no DllImport attribute.
Consider adding a DllImport attribute to specify the external
implementation
./Glx.cs(1418,42): error CS0626:
`Tao.Platform.X11.Glx.glXGetSelectedEvent(System.IntPtr,
System.IntPtr, ulong)' is marked as an external but has no DllImport
attribute. Consider adding a DllImport attribute to specify the
external implementation
Compilation failed: 4 error(s), 0 warnings
make[1]: *** [bin/Debug/Tao.Platform.X11.dll] Error 1
make[1]: Leaving directory
`/home/ekarlsso/downloads/tao/src/Tao.OpenGl/autotools/Tao.OpenGl/Tao.Platform.X1

Are these some well known issue or just a random situation in the trunk?

   Tao.Platform.X11 was checked in very recently so it's probably not
well known. You may try the attached patch.

Thanks. Patches worked fine. Was now able to compile the code.
