A few months ago I started a new job and was forced, against my wishes, to use Windows. One of the first things I tried to do is compile Cscope on my workstation. It has turned out to be quite a challenge to create a native Windows build of Cscope (I am unable to use Cygwin in my work environment). I decided to put the effort into facilitating such builds. The result is a forked version of Cscope, called min-cscope (for minimal and MinGW), which I believe may be of interest even to people who are working on "proper" operating systems...
The most notable changes from the mainline Cscope code are as follows: 1. CMake-based build system (die, autotools, die!). 2. The curses-based interface is optional (many people, including myself, are using Cscope as a backend process only, and dropping curses makes compilation on Windows considerably easier). Curses support is added only if CMake determines that the appropriate header and library exist. 3. Built-in sorting for the inverted index (replacing the piped invocation of a Unix-like sort application). The implementation is multi-platform, efficient (using considerably less memory than GNU sort, with about the same runtime) and provides progress information. 4. Uses a binary search in invmake() to locate the matching file index for the given offset. This dramatically cuts down on the time to build the inverted index (and can be easily applied to the current Cscope code). On my Linux machine, building the cross-reference database and the inverted index for the Linux kernel takes 41 seconds with Cscope, and 23 with min-cscope (both with a warm file cache) It is important to note that the database format is exactly the same as that of Cscope - only the build process has been affected. Thus, Cscope can be invoked on a database created by min-cscope and vice-versa. I have only tested min-cscope on Linux and Windows. When I have the time, I will also try it on FreeBSD and Solaris. I see no point in maintaining support for older Unix variants (it saddens me to say so, but it's reality).
