CMAKE_EXECUTABLE_SUFFIX doesn't seem to be working for FPrime v4.0.0a1

[ethancheez]

This line in ArduinoFw.cmake was added to fix the rpipico builds. A .elf extension needed to be added to the binary.

set(CMAKE_EXECUTABLE_SUFFIX "${FPRIME_ARDUINO_EXECUTABLE_SUFFIX}" CACHE INTERNAL "" FORCE)

These lines in arduino-support.cmake sets the .elf extension:

# Set the executable suffix if not defined
if (NOT DEFINED FPRIME_ARDUINO_EXECUTABLE_SUFFIX)
    set(FPRIME_ARDUINO_EXECUTABLE_SUFFIX ".elf")
endif()

However this doesn't work anymore when building for rpipico and rpipicow. See output after running fprime-util build rpipicow:

ERROR: filename '/randompath/fprime-tutorial-arduino-blinker/build-fprime-automatic-rpipicow/bin/rpipicow/LedBlinker' does not have a recognized file type (extension)
[ARDUINO WRAPPER POST BUILD WARNING] Error in executing: /home/user/.arduino15/packages/rp2040/tools/pqt-picotool/4.0.1-8ec9d6f/picotool uf2 convert /randompath/fprime-tutorial-arduino-blinker/build-fprime-automatic-rpipicow/bin/rpipicow/LedBlinker /randompath/fprime-tutorial-arduino-blinker/build-fprime-automatic-rpipicow/bin/rpipicow/LedBlinker.uf2 --family rp2040

In the end, this generates an empty LedBlinker.uf2 in the build-artifacts directory.

This works on F Prime v3.6.3
Did something change in the fprime build from v3.6.3 to v4.0.0a1?

I'm getting the same error. Looking into it

Looks like this is fixed. Thanks!
