Windows Debug hello World -> Unable to launch Rust Project from selection

See original GitHub issue

I installed rust, eclipse, created a new cargo project and tried to launch it.

Eclipse opened the settings panel complaining: “install missing rls component in rustup” I installed rustup component add rls-preview rust-analysis rust-src and the message was gone. It would have been nice to get a better help than “install missing rls component in rustup”

Running the application worked fine now, but debugging gave me:

I should mention, that I’m a rust newcomer without hardly any C/C++ background, but I suppose this actually should run “out of the box”?

@Boereck Yes it’s strange. I’ve just tried it again and shows now the error log:

org.eclipse.cdt.dsf.gdb

No idea why Python shows problem during launch of the GDB executable… The same gdb.exe is working with “C/C++ Application” debug config!

OK, now it works with MinGW GDB 8.2 if i create other debug config like described in #138 under “C/C++ Application” and full path to executable image

with .gdbinit for rust pretty printers --> it stops at breakpoint and shows the Variables 😃 image

So there is something different in debug config under “Rust” for launching gdb with working dir or exe path…
