Description
Describe the problem
Under the following conditions:
- A custom build path is set via the
--build-pathflag. - The build path is on a different drive from the system temporary folder.
core caching fails:
Couldn't deeply cache core build: Rel: can't make E:\build-path relative to C:\Users\per\AppData\Local\Temp\arduino\cores
To reproduce
$ arduino-cli version
arduino-cli.exe Version: git-snapshot Commit: 2c2a5cc6 Date: 2023-04-24T05:04:04Z
$ arduino-cli sketch new "e:/FooSketch" # The sketch path must be on the same drive as the build path due to arduino/arduino-cli#2156
Sketch created in: e:\FooSketch
$ arduino-cli compile --build-path "e:/build-path" --fqbn arduino:avr:uno "e:/FooSketch"
Couldn't deeply cache core build: Rel: can't make e:\build-path relative to C:\Users\per\AppData\Local\Temp\arduino\cores
Running normal build of the core...
Sketch uses 444 bytes (1%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.
Used platform Version Path
arduino:avr 1.8.6 C:\Users\per\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.6
Expected behavior
Core caching to be done regardless of build path location.
Arduino CLI version
Operating system
Windows
Operating system version
11
Additional context
I was not able to reproduce the fault on Linux or macOS
Issue checklist
- I searched for previous reports in the issue tracker
- I verified the problem still occurs when using the nightly build
