RunProdServer tries to find RunDevServer oddly?

[nomeata]

I am experimenting with IHP now, with a small site for a local club – I’m too proud to not use a custom domain name, but the club is far too small to pay for the cloud tiers. So I guess I’ll run it on a personal server of mine, a Debian server with nix installed.

Nicely, IHP provides the nix-based deployment builds, so that should hopefully make things easy. But I didn't get very far:

$ nix-build 
…
[16 of 16] Compiling Main             ( Main.hs, build/RunUnoptimizedProdServer/Main.o, build/RunUnoptimizedProdServer/Main.dyn_o )
Linking build/bin/RunUnoptimizedProdServer ...
chmod +x Main.hs
rm -f build/bin/RunProdServer
ln -s `basename build/bin/RunUnoptimizedProdServer` build/bin/RunProdServer

$ /nix/store/l6vmnyfs4vc0kb0kprr8mhzkwch6xnx4-app/bin/RunProdServer
dirname: fehlender Operand
„dirname --help“ liefert weitere Informationen.
RunProdServerWithoutOptions: readCreateProcess: dirname $(which RunDevServer) (exit 1): failed

Why is RunProdServer trying to find RunDevServer?

Oh, and does anyone have a nixos module generator for IHP projects around? Seems to be a natural fit…

Why is RunProdServer trying to find RunDevServer?

IHP uses the location of the binary to find the location of the IHP lib directory.

If you switch the working directory to $out/lib the IHP app should be able to start :)

You can find an example nix configuration here: #1292 (comment)

I've created #1457 to improve this 👍
