hi, maybe somebody can help me. At the moment I'm reading the "Winelib User's Guide" and I also tried out the "1.3.2. Test Drive". Almost everything work. After changing the Makefile it compiled with no error. this is my result when i start the created notepad2.exe.so Code: $ ./notepad2.exe.so Segmentation fault This is the user guide http://www.winehq.org/site/docs/winelib-guide/winelib-getting-started Thanks Uwe
