Note: This software is still in early-phase development, and has not been released.

We strive to provide first-class support to all of the common GNU glibc or musl-based Linux distributions, as well as the *BSD operating systems on a when-possible basis. Regardless, if your target platform is not listed here, or the package is out-of-date, you have a series of options on how to proceed (ranked from most to least preferred).

  • Contact upstream: If orcircd is supported through official channels, contact those maintainers and request an update.
  • Contact us: If you are using a package maintained by us, write an email to ~brettgilio/
  • Build from source / use opam: Continue reading…

Generally, we recommend using the package which was built against your target platform. These packages are carefully crafted, and take into account possible defects particular to your target platform. If you choose to proceed with a source build / opam and experience a defect, please let us know! If you are targeting Microsoft Windows or macOS, please read the relevant entry in the FAQ.


Building orcircd from source is best achieved by using the opam tooling. This will enable you to manage your OCaml installation, and automate the process of compiling orcircd. Additionally, you will need a C compiler capable of compiling at least C99. Proceed to install the following dependencies:

  • opam
  • pkg-config / pkgconf
  • gcc (or another C99-compliant compiler)
  • make

Next, initialize opam. Create a switch tracking a recent version of OCaml, we recommend >=4.10.0.

$ opam init
$ opam switch create 4.10.0

Now, we can use opam to build and install orcircd.

$ opam install orcircd

If you wish to build and install a development version of orcircd, or are using a platform without official support, please follow the instructions outlined in HACKING.
