Dear All,
I would greatly appreciate a nudge in the right direction concerning
the use of cwd argument in the call function from subprocess module.
The setup is as follows:
driver.py <- python script
core/ <- directory
main <- fortran executable in the core directory
driver script generates some input files in the core directory. Main
should do its thing and dump the output files back into core.
The problem is, I can't figure out how to do this properly.
call("core/main") works but uses .. of core for input/output.
call("core/main",cwd="core") and call("main",cwd="core") both result in
File "driver.py", line 47, in <module>
main()
File "driver.py", line 40, in main
print "OUT", call("core/main", cwd="core")
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/
python2.5/subprocess.py", line 443, in call
return Popen(*popenargs, **kwargs).wait()
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/
python2.5/subprocess.py", line 593, in __init__
errread, errwrite)
File "/Library/Frameworks/Python.framework/Versions/2.5/lib/
python2.5/subprocess.py", line 1051, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
perhaps if subprocess would indicate the abs path of the object in
question I could figure it out, but as is I'm lost.
