["Error while launching command: gdb --version"]. Examples of nRF52.

Hi there,

Thanks to the great tutorial from Vidar, I can play with the blinky example in Eclipse on Mac. Now I want to try the other examples, and encountered the "Error while launching command: gdb --version".

With the enlightenings from the discussionand Montaner's tutotial , I have built the new project with "makefile Project with Existing Code".

I can compile and get binaries, but when I try to debug in Eclipse, I encountered problem.

---

This is what did to configure the project. Then according to Montaner's tutorial, and following the working project of blinky, I

1. Add new folders and import new files, i.e., folder "Application" contains main.c, the folder "Device" includes the same files in the blinky project.
2. Add includes paths which appear in the Makefile. Now the project looks like this:

There are still some errors with the included paths, but I can still compile with ctrl+B.

Then problem comes: I can not debug! This is the debug configuration: and

I went back to check the setting of debugger, find it is alright.

Could anyone give me any hints? thanks!

Hi,

I haven't figured out why yet, but for some reason the ${cross_prefix} is not always being set to arm-none-eabi (used in the executable field of the GDB Client setup). It's probably related to the project setup. The result is that the debug launcher calls gdb --version while it should call arm-none-eabi-gdb --version.

Fix:

Change ${cross_prefix}gdb${cross_suffix} to arm-none-eabi-gdb

@Vidar Berg, After this example, I encountered several more times when I debug the examples in Eclipse. My 'standard' workaround is, property->c/c++ build->Build variables, then add the PATH (the table is empty when I opened it for the first time).
