Building

To be able to build houdini you need to download a corresponding build installer from sidefx site

Add downloaded installer to the store with nix-store --add-fixed sha256 houdini-19.0.720-linux_x86_64_gcc9.3.tar.gz (with proper filename of course)

then you can run corresponding houdini version without cloning repo or downloading anything with simple command:

nix run github:pedohorse/houdini-nix#houdini-19_0_720 houdini

Note

Further down I will refer to this flake as if it was in the current directory, so instead of github:pedohorse/houdini-nix I'll write just .

You can build the flake's output instead with:

nix build .#houdini-19_0_720

and have some houdini binaries available in ./result/bin

Running

There are several ways you can run houdini with this flake.

Building and using ./result

After building with command like nix build .#houdini-19_0_720, you will have the usual result symlink created. all (hopefully) important binaries are exposed in ./result/bin directory.

This creats a more usual file structure, to which you can point your pipeline usual tools, that expect to run binaries directly

Running flake

You can also run the flake's outputs directly, as in

nix run .#houdini-19_5_569 houdini
nix run .#houdini-19_5_569 houdinifx
nix run .#houdini-19_5_569 houdinicore
etc

Note

not all houdini's binaries are exposed now, only the ones deemed "useful", so feel free to open issue in case something you need is missing

On sesinetd:

sesinetd is houdini's licensing server. There is a special set of flake outputs to run it. You need to provide the script with a path to a writeable directory where the licenses are to be stored.

nix run .#sesinetd-19_5_569 -- /path/to/lic/dir --other sesinetd -arg uments

for example, an easy way to run license server from houdini version 19.5.733, as your user named artist, and store licenses in relative dir ./hlicenses you run:

nix run .#sesinetd-19_5_773 -- ./hlicenses --user artist --group artist -D

this will run license server in foreground (-D flag) in the terminal, so you can kill it with Ctrl+C
