in commit 8dd0ec6, the `GDB_ARGS` variable was split across 3 lines. However, extra quotes were added to each line, such that the shell interprets the 3 lines as space separated strings, and tries to execute the latter two lines. This commit simply removes the extra quotes.

rust-gdbgui
|
|
===========
|
|
gdbgui - https://gdbgui.com - is a graphical front-end to GDB
|
|
that runs in a browser. This script invokes gdbgui with the Rust
|
|
pretty printers loaded.
|
|
|
|
Simple usage : rust-gdbgui target/debug/myprog
|
|
With arguments: rust-gdbgui 'target/debug/myprog arg1 arg2...'
|
|
(note the quotes)
|
|
|
|
|
|
Hints
|
|
=====
|
|
gdbgui won't be able to find the rust 'main' method automatically, so
|
|
in its options make sure to disable the 'Add breakpoint to main after
|
|
loading executable' setting to avoid a 'File not found: main' warning
|
|
on startup.
|
|
|
|
Instead, type 'main' into gdbgui's file browser and you should get
|
|
auto-completion on the filename. Just pick 'main.rs', add a breakpoint
|
|
by clicking in the line number gutter, and type 'r' or hit the Restart
|
|
icon to start your program running.
