Well the output of Code: /home/user/download> sudo apt-get build-dep wine Reading package lists... Done Building dependency tree... Done E: Unable to find a source package for wine doesn't get me any further. Know that i'm missing something obvious here! [Laughing] apt needs to know the source of wine, which is http://sourceforge.net/project/showfiles.php?group_id=6241&package_id=77449 (http://sourceforge.net/project/showfiles.php?group_id=6241&package_id=77449), and is now unzipped in /home/user/download/wine-1.1.21. The apt-how to says > All source packages have a field in their control files called 'Build-Depends:' that indicates which additional packages are needed for the package to be built from source. but there doesn't seem to be a Build-Depends? How/what address does apt need to get this information. Is it an addition to my /etc/apt/sources.list? :D The Recommended_Packages (http://wiki.winehq.org/Recommended_Packages) in the wiki lists various x packages, can i just install them separately? Will that solve this?
