I'm watching video with @WojciechMazur, and I think this bit is incorrect?
I.e. I'd expect native0.4 to go before the scala version
I.e. that's what is being published now: https://repo1.maven.org/maven2/org/typelevel/cats-core_native0.4_2.13/2.6.1/
nvm found it :)
I think that is adjacent. 32 bit is a breaking NIR change so I think that is why it is planned for 0.5.0. Perhaps using the shared library would work for WASM. Pretty sure that is not merged yet. Perhaps someone with an interest needs to work on it and see what can be done.
Please vote if you use IntelliJ IDEA for projects with CrossType.Full cross-build: https://youtrack.jetbrains.com/issue/SCL-19567
@ankusharya Yes, I had the
0.4.0-M2 and it works in WSL1 (I am unable to get networking to work in WSL2). So 0.4.0 works as well. Do you have your project on the WSL filesystem? I remember reports that it won't work if the project is on the C drive. Release 0.4.1 coming soon will have initial support for native Windows (non-WSL) as well. You could try adding logLevel := Level.Debug in your build.sbt to see if you get more info on the crash.
We are also on Discord - https://discord.gg/scala
I tried publishing a local library with
0.4.1 and tried to use the library in a 0.4.0 project

updating the project to
0.4.1 links correctly
@ekrich I develop small automation tools for some tasks. I recently switched to Windows. Thanks for the reply. I have opened a bug on scalanative issues page and provided all the details about my setup and ways to reproduce it. I also on discord and have joined the
scala server there but i thought scala-native channel on discord is not the right place to ask about such issue.
I'm on arch linux trying to use os-lib and I'm getting some linker errors:
[error] Found 2 missing definitions while linking

@ayush9999-qa I think you want to ask this question in discord's
#scala-users channel. This channel is specific to the Scala Native project: https://scala-native.readthedocs.io

I don't have an authoritative answer but I don't see why not given the hardware specs. Even 32-bit support has been in the works for a while scala-native/scala-native#1571
@Sciss I have run Scala Native on Rasp PI 4 with 64 bit Ubuntu and also have made hello world work for the 32bit branch. In both these cases I used Java on the box to run sbt to compile and link. With only 512, I think you would have to cross compile on something else with more memory.
Yes, it work unchanged on 64 bit ARM. I have not cross compiled on AMD for ARM. We added the ability to provide the target triple but don't know how the rest of that process works - install the ARM includes and libs? If you can achieve this is would be great to add a How-to in the docs. All we have so far - https://scala-native.readthedocs.io/en/latest/user/sbt.html#cross-compilation-using-target-triple
