Unable to locate build tool "GNU PX4 Archiver": echo

Hi, I recently updated to r2109a with the new PX4 support. I did everything accordoing to the instruction and built a firmare and got some accelerometer measurements.

When I try to build in a demo model for example px4demo_uORBRead, i get this error:

Error(s) encountered while building "uorb_demo":
### Failed to generate all binary outputs.
Caused by:
Validation error(s): 
### Validating other build tools ...
Unable to locate build tool "GNU PX4 Archiver": echo .

I tried both cygwin and built in cmake, they dont work. any ideas?

Thanks.

Had the same problem.

Try to copy the file "bash.exe" from C:\Windows\system32 to C:\Windows\SysWOW64

There is a issue of 32bit vs. 64 bit programs.

See link below for more details:

You are correct, I have fixed this issue by using:

setenv('MW_PX4_WIN10_BUILDCMD', 'cmd /c start cmd /k "C:/Windows/Sysnative/bash.exe -cli "make $(CMAKEMAKECONFIG) " 2> MWPX4BuildLog.txt & echo MW_BUILD_COMPLETE >> MWPX4BuildLog.txt " ');

Before I build the firmware (needs to be done every time).

You need not do it everytime before building the Firmware. Use the below command once :

setpref('MW_PX4_WSLBuildPath','SwitchPath', 1)

Refer to this link for more information.

I had this problem when using Cygwin and it went away by switching back to Ubuntu LTS. This was a nice long-term solution for me. For anyone curious where these get set, my location was

C:\ProgramData\MATLAB\SupportPackages\R2019a\toolbox\target\supportpackages\px4\+codertarget\+pixhawk\+internal\setupBuildEnvironment.m

This helped me debug.

setpref('MW_PX4_WindowsToolchain','UseCygwin', false)
