[issue15020] Poor default value for progname
New submission from Joshua Cogliati jrinc...@gmail.com: In Python/pythonrun.c the following definition exists: static wchar_t *progname = Lpython; This is then used by Py_GetProgramName which is used by calculate_path in Modules/getpath.c Since in python 3, the default executable is python3, and not python, when calculate_path searches for python it will find where python 2 is installed instead of where python3 is installed. This is the error message that this causes: Could not find platform independent libraries prefix Could not find platform dependent libraries exec_prefix Consider setting $PYTHONHOME to prefix[:exec_prefix] I recommend that line be changed to: static wchar_t *progname = Lpython3; since that is the default executable name. For my purposes (which is making an executable that embedds python 3), I was able to work around this by calling: Py_SetProgramName(Lpython3); before Py_Initialize(); -- messages: 162425 nosy: Joshua.Cogliati priority: normal severity: normal status: open title: Poor default value for progname type: behavior versions: Python 3.2 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15020 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
