However the Cygwin version is very slow compared to Linux, even I compiled with the optimize option -O2. It is a Windows 2000, the program is a segmentation editor using Qt, OpenGl and some image processing. What is the reason? Is it OpenGL on cygwin, or both? Here is the library dependency list: segeditorMax.exe C:\cygwin\usr\X11R6\bin\libGL.dll C:\cygwin\usr\X11R6\bin\libX11.dll C:\cygwin\bin\cygwin1.dll C:\winnt\System32\KERNEL32.dll C:\winnt\System32\NTDLL.DLL C:\cygwin\usr\X11R6\bin\libXext.dll C:\cygwin\usr\X11R6\bin\libGLU.dll c:\qt-cygwin\qt-3\bin\cygqt-mt-3.dll C:\cygwin\usr\X11R6\bin\libICE.dll C:\cygwin\usr\X11R6\bin\libSM.dll C:\cygwin\usr\X11R6\bin\libXrender.dll C:\cygwin\bin\cygpng12.dll C:\cygwin\bin\cygz.dll C:\winnt\System32\ADVAPI32.DLL C:\winnt\System32\RPCRT4.DLL c:\Vlad\build\Dev\lib\libOip.dll C:\winnt\System32\GDI32.dll C:\winnt\System32\USER32.DLL -- Vladimir Baltchev Senior Software Developer @ Orthosoft R&D Inc Tel (514) 861-1837 ext 230 Email: Vladimir DOT Baltchev AT orthosoft DOT ca -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
