Building Panda3D with OpenGL ES using Cygwin and MSVC9. Log

[darkphoenix16]

It is hard to say. My sample is all in one file so it's easier to follow. I'm still workout out the use of Pipes, Buffers, and Windows

Hey.

Been away for a while. I had to shift priority back to some other work.

Anyways. I've got the display set up. I had to change the config options for eglChooseConfig to work. I've since encountered two problems. The first was that Panda couldn't find an appropriate set of FrameBuffer properties. It could only get hardware_accel=1, not RGB, ALPHA, DEPTH, and BACK BUFFER...which seemed strange. To just hack past this is I commented out the code which adds those missing properties.

Next I get this

Code: Select all

Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call.  This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.

I was able to get rid of the GL enumeration warning by forcibly disabling cube map support.

So no ideas on the ESP crash posted above?
