OSX Problem to get debug from cache. Error: Unable to find GDB in default search path

Brief Issue Summary

On OSX with a cross compiler in $ARMGCC_DIR attempting to debug via jtag with cortex-debug yields the error:

“Problem to get debug from cache. Error: Unable to find GDB in default search path and /usr/local/opt/toolchain/lldb-arm-none-eabi/bin/arm-none-eabi-lldb.”

from CMake Tools

this is with gdb installed in /usr/local/bin, the same place cmake is installed and cmake.cmakePath=“/usr/local/bin/cmake”

I don’t expect that an arm-none-eabi-lldb is required if my jtag is acting as a gdb server, so what do I do to get rid of this error so that CMake can see gdb?

Expected:

1. configure CMake tools to create a CMakeCache that stores the location of gdb
2. click the “Debug” button
3. gdb launches and attaches

Apparent Behavior:

CMake configure seems to not be aware of my PATH? or perhaps only the path to the debugger . I can compile fine, which requires access to environment variables and an updated PATH (to point to my cross-compiler) . what I am not getting is why “Unable to find GDB in default search path” is occuring

1. Push button
2. CMake tools reports Unable to find GDB

In your project .vscode/settings.json you can write this:

"cmake.debugConfig": {
    "miDebuggerPath": "define/your/path/here"
}

@andreeis How does one “Set cmake.debugConfig - miDebuggerPath”?
