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