I am looking for some guidance on using subprocess to execute an EXE with
arguments and an output. The below code works in that it returns a 0 exit
code, but no output file is created. I have tried a few different versions of
this code (used Popen instead, some stderr/stdout), but no luck. Can anyone
offer an explanation or suggestion? (GPSBabel is freeware)
Python 2.7 on windows7 64-bit
import subprocess
subprocess.call([r"C:\Program Files (x86)\GPSBabel\gpsbabel.exe",
"-i", "gdb", "-f", r"C:\Temp\GDBdata\testgps28.gdb",
"-o", "gpx", r"C:\Temp\gpx\test28output.gpx"])
If I use this below, I get a returncode of 1, exit code of 0.
import subprocess
x = subprocess.Popen([r"C:\Program Files (x86)\GPSBabel\gpsbabel.exe",
"-i", "gdb", "-f", r"C:\Temp\GDBdata\testgps28.gdb",
"-o", "gpx", r"C:\Temp\gpx\test28output.gpx",
"shell=True", "stdout=subprocess.PIPE",
"stderr=subprocess.PIPE"])
x.wait()
print x.returncode
Thanks in advance for any help
