Introduction

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.

To keep up to date with the current stable release of kcgi, visit https://kristaps.bsd.lv/kcgi. The website also contains canonical installation, deployment, examples, and usage documentation.

Installation

You'll need a C compiler (gcc or clang), zlib (zlib or zlib-dev for some package managers), and BSD make (bmake for some managers) for building.

On some Linux systems, you might additionally need the Linux kernel headers installed using the linux-headers package or similar.

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
make install

A common idiom for deploying on Linux is to use libbsd as noted in the oconfigure documentation:

./configure \
CFLAGS=$(pkg-config --cflags libbsd-overlay) \
LDFLAGS=$(pkg-config --libs libbsd-overlay)
make
make install

Testing

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.) You'll need libcurl installed (curl-dev, libcurl-dev, or libcurl4-openssl-dev with some package managers).

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

The public GitHub repository repository for kcgi uses automated testing on each check-in to run the regression tests. These automated tests are primarily aimed at Linux, whose security mechanism requires constant maintenance. The following systems are checked:

  • Alpine/musl Linux (latest, aarch64, sandboxed)
  • Alpine/musl Linux (latest, armv7, sandboxed)
  • Alpine/musl Linux (latest, ppc64le, sandboxed)
  • Alpine/musl Linux (latest, s390x, sandboxed)
  • Alpine/musl Linux (latest, x86_64, sandboxed)
  • FreeBSD (latest, x86_64, sandboxed)
  • Mac OS X (latest, arm64, sandboxed)
  • Ubuntu/glibc Linux (latest, x86_64, un-sandboxed)
  • Ubuntu/glibc Linux (latest, x86_64, sandboxed)
  • Ubuntu/glibc Linux (latest, x86_64, sandboxed, libbsd)

Development is primarily on OpenBSD.

These are also run weekly to catch any changes as new operating system features come into play.

make install

Testing

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.) You'll need libcurl installed (curl-dev, libcurl-dev, or libcurl4-openssl-dev with some package managers).

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

The public GitHub repository repository for kcgi uses automated testing on each check-in to run the regression tests. These automated tests are primarily aimed at Linux, whose security mechanism requires constant maintenance. The following systems are checked:

  • Alpine/musl Linux (latest, aarch64, sandboxed)
  • Alpine/musl Linux (latest, armv7, sandboxed)
  • Alpine/musl Linux (latest, ppc64le, sandboxed)
  • Alpine/musl Linux (latest, s390x, sandboxed)
  • Alpine/musl Linux (latest, x86_64, sandboxed)
  • FreeBSD (latest, x86_64, sandboxed)
  • Mac OS X (latest, arm64, sandboxed)
  • Ubuntu/glibc Linux (latest, x86_64, un-sandboxed)
  • Ubuntu/glibc Linux (latest, x86_64, sandboxed)
  • Ubuntu/glibc Linux (latest, x86_64, sandboxed, libbsd)

Development is primarily on OpenBSD.

These are also run weekly to catch any changes as new operating system features come into play.

Introduction

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.

To keep up to date with the current stable release of kcgi, visit https://kristaps.bsd.lv/kcgi. The website also contains canonical installation, deployment, examples, and usage documentation.

Installation

You'll need a C compiler (gcc or clang), zlib (zlib or zlib-dev for some package managers), and BSD make (bmake for some managers) for building.

On some Linux systems, you might additionally need the Linux kernel headers installed using the linux-headers package or similar.

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
make install

A common idiom for deploying on Linux is to use libbsd as noted in the oconfigure documentation:

./configure \
CFLAGS=$(pkg-config --cflags libbsd-overlay) \
LDFLAGS=$(pkg-config --libs libbsd-overlay)
make
make install

Testing

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.) You'll need libcurl installed (curl-dev, libcurl-dev, or libcurl4-openssl-dev with some package managers).
