I'm trying to configure PlatformIO with CLion for an 8051-based project using the SDCC toolchain.

• The sdcc.exe file exists at the correct path and runs successfully from the command line, but CLion cannot find it when building the project:

Unknown compiler executable: 'C:\Users\lyz\.platformio\packages\toolchain-sdcc\bin\sdcc.exe'

• The SDCC toolchain is installed at

C:\Users\lyz\.platformio\packages\toolchain-sdcc\bin\sdcc.exe.

• The project builds successfully from the command line using pio run, but CLion's PlatformIO plugin fails to recognize sdcc.exe.

• I've verified that the file exists and can be executed directly from the terminal, but CLion does not detect it during the build process.

• I’ve tried setting the correct toolchain path in the platformio.ini file, but the issue persists.

How can I resolve this and make CLion properly recognize the SDCC toolchain?

• Reinstall the toolchain

Try downgrading the Clion version to 2024.2.4 or lower, that's how I solved it
