Hi

I need to debug swift 5.2.x in Ubuntu , But it always show me that problem

Can you please try removing lldb.libpython from your configuration settings?

smumriak commented 4 years ago

@vadimcn i tried that. it will not help. i think the problem is in the fact that liblldb shipped with swift is linked to libpython of different version (or forked version, who knows) that is found on the system. removing the liblldb condig allows me to launch the debug session, but there's no proper symbols and p/po commands to not work. breakpoints do work tho :)

lokinfey commented 4 years ago

I try all method , but it can not show local variable in VSCode debug mode ...........

I get similar errors when trying to use an external liblldb on Ubuntu 18.04, tried Swift 5.1.5 and 5.3, setting lldb.libpython to either the 3.6 or the 2.7 .so, all resulting in the same error:

Please upgrade to v1.6 and try again.. I've tested with Swift 5.3.

svanimpe commented 4 years ago

@lokinfey @andigena @smumryak Can you try out setup instructions for VS Code here? https://github.com/pwsacademy/swift-setup/blob/main/editors/vscode-linux/README.md

These have been tested on the various distributions we support (Ubuntu, Fedora, and derivatives), so check the instructions for those platforms as well, in case you’ve set up Swift differently.

@svanimpe Just got around to try this out and everything seems to work. Thank you!
