Is there a way of speeding up an alr build with gtk? Say I start a new project.
alr init --bin a98xml
alr with gtk
That is simple enough.
alr build
This takes about 4 minutes. We only have to do this once but it is 4 minutes for every project I get out of source code control. Is it safe to do this once and then copy the alire/cache directory to all the projects?
I've tried it. It seems to work but how safe is it?
If you’re using an up-to-date alr (I’m using 2.0.1, which isn’t the latest) you could check this setting (alr help settings):
- dependencies.shared [Boolean][Default:TRUE] When true, dependencies are downloaded and built in a shared location inside the global cache. When false, dependencies are sandboxed in each workspace.
If true, release builds are cached (look in alr version for build folder) using some long hash. I don’t know what makes up the hash, it’ll be some mix of compiler/flags used for the build.
I’m using aarch64-apple-darwin (Macbook Air M1), and I’ve noticed that using the default gprbuild some crates (e.g. langkit, libadalang) get rebuilt anyway.
