The PX4 firmware build fails consistently for SITL

Hello,

I am trying to use simulink and px4 to perform SITL. but when i am setting up the hardware, i am not able to buide the firmware. I tried multiple time but no success.

This is the error i am getting. I tried selecting Pixhwak 6X, still i am not able to build firmware.

Can you try reinstalling the Cygwin toolchain?

Maybe a mistake here ??? ->

px4_add_library(monocypher

monocypher/src/monocypher.c

monocypher/src/optional/monocypher-ed25519.c

)

target_include_directories(monocypher

PUBLIC

${CMAKE_CURRENT_SOURCE_DIR}/monocypher/src

)

# There is a one shadow warning in monocypher 3.1.2, ignore it

target_compile_options(monocypher PRIVATE -Wno-shadow)

It seems that the problem is on "cygdrive/c/PX4_cygwin/home/Firmware/build/px4_sitl_default"

make sure that the firmware folder is on home directory not in "home/mypx4" or anything else.

also it is suggested to install on "C:\PX4" instead of "C:\PX4_cygwin"

can you access C drive to write something? i mean are you an administrator user?
