My colleague, Alex Pescaru, suggested to study the dependencies.
Using "depends.exe" I loaded "OCTAVE_Test_0002.exe"
and I noticed that:
a) GLU32.DLL, identified as a 64 bits application uses OPENGL32.DLL, which is also identified as a 64 bits application, while
b) LIBGL2PS.DLL is not identified as a 64 bits application and it also uses OPENGL32.DLL (which is a 64 bits computer code).
The error message is "The procedure entry point address@hidden could not be located in the dynamic link library C:\Octave\Octave-22.214.171.124\mingw32\bin\libgl2ps.dll", see
MinGW, Eclipse, Octave, all are 32 bits applications.
By the way, there are several versions of g++ and gcc,
Any suggestion is welcome.
