Hi all, i am trying to build Qt 5.9.3 and build failed on bootstrap.py with: Building gn manually in a temporary

Stop.Any suggestions? My build configuration is:

My case is solved: The path generated for the python script was too long for Windows. After shortening the path WebEngine compiled for me.
@Elgerton I have the same issue. How do you shorten the file path?

I'm have the same problem at Qt 5.9.6
I'm solve it.
Solution is very strange.
I'm add inside file C:\Python27\lib\subprocess.py
information about arg, and figure out:
error was happend when call mc.exe with parameters, but without absolute path just as:
mc.exe -bla bla
mc.exe - is utility from SDK, and PATH do not contain path to it.
after path to mc.exe added to PATH build is continue.I hope everybody who find this topic with same problem will get it as solution.
