Greetings good people and thank you for your help - I managed to compile Wine 0.9.53 successfully! I just added this two lines at the begining of signal_i386.c file: #define VIF_MASK 0x00080000 #define VIP_MASK 0x00100000 It takes long time to do Reverse Regression Testing maybe because I'm still not that familiar with Git (I'll do it anyway because I want to learn how to do it). But now I have another problem and I hope you'll help me with this: I set "/home/myself/winebuilds/wine-0.9.53" for install folder and use "checkinstall" to create deb package but after the installation Wine won't run no matter what I do ?! If I run winecfg or winever from /home/myself/winebuilds/wine-0.9.53/bin it says command not found and when I choose to install Wine from repos it overwrites my version of Wine. All I want is to have "stable" version of Wine installed in its default location and versions of Wine compiled by me installed in a different location - How can I achieve that and what am I doing wrong here? Thanks in advance...
