Troubleshooting

Take inspiration for other distributions

If you are not on the supported distributions, but you are interested a native setup

• You can probably reuse or adapt the two Bash scripts asm.x86-arm.sh and asm.x86-i686.sh to install the 2 toolchains
• You can find the list DNF of dependencies by looking at my playbook asm.yml
• Also look at base.yml
• You need to install asm.fish and r.fish and cmr.fish via lxup get <tool>, once you have lxup
• You may want to install Eclipse, you can do it with snap

Ask me on Teams or by email for help if you are stuck ! I'm happy to give some help.

Notes

These errors shown when running ./st seem to not be a problem, as they also appear in the provided VM...

On Fedora, IIUC there is no equivalent to this, things are probably already installed if it compiles and run.

sudo apt install gcc-multilib

Debugging debug

arm-none-linux-gnueabihf-gdb seems to require python 2.8 which is obsolete. Actually, this is useless to try to fix that, because gdb on Fedora and gdb-multiarch on Ubuntu, seems to be enough.

Remaining experience issues

If anybody want to dig into this and document solutions, I'm more than happy to integrate them !

Build before run and watch mode in asm CLI

Like sr in SYE, this is going to be developed one day. I have no more time for now.

Build before debug in asm CLI

This is hard to implement, because I cannot figure out to avoid VSCode to start annoying popups of debug timeout, when the project fails to build.

No syntax highlighting in VSCode

These tree-sitter syntaxes could be tested and installed.

• https://github.com/RubixDev/tree-sitter-asm/
• https://github.com/ram02z/tree-sitter-fish

No language server

This project asm-lsp looks promising, but doesn't have a VSCode extension. https://github.com/bergercookie/asm-lsp

Debug configuration in other IDEs

Is there a way to recreate the same experience in Neovim, like the debug experience of VSCode ?
