getting libcairo not found

i tried setting both of these... but no dice: NIXPACKS_APT_PKGS=libcairo2,libcairo2-dev NIXPACKS_PKGS= cairo i still get this in my logs: when i run sudo apt install libcairo2 and libcairo2-dev on jammy... everything works in my build should i just stick that in the run command? seems hacky

it would be best for you to build your app with a dockerfile

didn't even know nix supported dockerfiles how do i convince it to use a dockerfile?

nixpacks and dockerfiles are not mutually exclusive, if you are using a dockerfile nixpacks has nothing to do with the build anymore you simply place a Dockerfile in your repo

cool the thing is... it really looks like it's doing the right thing: #9 17.60 Unpacking libcairo2:amd64 (1.16.0-5ubuntu2) ... #9 17.63 Selecting previously unselected package libcairo-gobject2:amd64. i suspect it's a path thing.

oh I know, it is doing the right thing but for some unknown reason during runtime it's like none of that stuff was ever installed better to just use a Dockerfile for this kind of thing so you don't have to deal with the nixpacks stuff

if i use a dockerfile... do i still get the environment variables exposed nicely with the control panel?
Brody

yes of course

everything works... and the builds are faster because i can carefully control the layers. thanks a lot.

no problem! a Dockerfile is always going to be the go to for people who want absolute control over their build
