kcgi is an open source CGI and FastCGI library for C/C++ web applications. It's minimal, secure, auditable, and fits within your BCHS software stack.

This repository consists of bleeding-edge code between versions: to keep up to date with the current stable release of kcgi, visit the website. The website also contains canonical installation, deployment, examples, and usage documentation.

What follows describes using the bleeding-edge version of the system.


To use the bleeding-edge version of kcgi (instead of from your system's packages or a stable version), the process it the similar as for source releases.

Begin by cloning or downloading. Then configure with ./configure, compile with make (BSD make, so it may be bmake on your system), then make install (or use sudo or doas, if applicable). To install in an alternative directory to /usr/local, set the PREFIX variable when you run configure.

./configure PREFIX=~/.local
make install

If you plan on using pkg-config with the above invocation, make sure that ~/.local/lib/pkgconfig is recognised as a path to package specifications. You'll also want to make sure that man can access the installed location of ~/.local/man, in this case.


It's useful to run the installed regression tests on the bleeding edge sources. (Again, this uses BSD make, so it may be bmake on your system.)

make regress

The system contains a full regression suite and is also built to work with AFL. To run some of the bundled tests, use the binaries compiled into the afl directory. (Again, this uses BSD make, so it may be bmake on your system.)

make afl
cd afl
afl-fuzz -i in/urlencoded -o out -- ./afl-urlencoded


All sources use the ISC (like OpenBSD) license. See the file for details.
