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

agile rain
#

didn't even know nix supported dockerfiles

#

how do i convince it to use a dockerfile?

orchid narwhal
#

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.

orchid narwhal
#

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

agile rain
#

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

orchid narwhal
#

yes of course

agile rain
#

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

no problem!
