import subprocess, os my_env = os.environ # if your program should be able to modify the current env # otherwise my_env = os.environ.copy() # if it shouldn't # if you just want to add something to the existing LIBPATH my_env["LIBPATH"] = "/where/I/want/to/look/first:" + my_env["LIBPATH"] # otherwise my_env["LIBPATH"] = "/what/I/want" subprocess.Popen(my_program, env=my_env) Setting os.environ leaks memory under Mac OS and FreeBSD. I am not sure if this means that if you do this a gazillion times on a Mac you will have a problem. Laura -- https://mail.python.org/mailman/listinfo/python-list
