The Windows emulation SDK uses Visual Studio to build the demos and training courses. I don’t have visual studio but do have cygwin that provides compilers for windows target. Can I use the cygwin environment to build and run the demos? I tried the first training course and it compiles but the linker cannot find the opengles libraries (or it doesn’t recognize the format). I have the makefiles pointing to were the libs are located. Any help or is cygwin out of the question for a build environment. TNX
