You've got a whole mess of strings there. They need to be straightened
out. ;) If you are using r for raw string you only need it once at the
beginning, and it doesn't go inside the quotes. So, after all that's
fixed we get:
os.popen3(r'"C:\Program Files\... \EVC.exe" "C:\Test\...\Test.vcp" /MAKE "GFSDK - Win32 (WCE ARMV4) Release" /REBUILD')
Here's a few free suggestions at no extra charge. You don't really need
to use raw strings for Windows paths. Using forward slashed as always
worked fine for me. Also, it might be a good idea to split up the long
line, too. So this is how I would do it:
evc = '"C:/Program Files/... /EVC.exe"'
vcp = '"C:/Test/.../Test.vcp"'
switches = '/MAKE "GFSDK - Win32 (WCE ARMV4) Release" /REBUILD'
os.popen3(evc + ' ' + vcp + ' ' + switces)
Or better yet:
os.popen3('%s %s %s' % (evc, vcp, switches))
