Compiling 2.7.2 on OS/2
Hi All, I'm working on updating my port of Python 2.6.5 to v2.7.2 for the OS/2 platform. I have python.exe and python27.dll compiling find, but when starting to build sharedmods I'm getting the following error: running build running build_ext Traceback (most recent call last): File "./setup.py", line 2092, in <module> main() File "./setup.py", line 2087, in main 'Lib/smtpd.py'] File "U:/DEV/python-2.7.2/Lib/distutils/core.py", line 152, in setup dist.run_commands() File "U:/DEV/python-2.7.2/Lib/distutils/dist.py", line 953, in run_commands self.run_command(cmd) File "U:/DEV/python-2.7.2/Lib/distutils/dist.py", line 972, in run_command cmd_obj.run() File "U:/DEV/python-2.7.2/Lib/distutils/command/build.py", line 127, in run self.run_command(cmd_name) File "U:/DEV/python-2.7.2/Lib/distutils/cmd.py", line 326, in run_command self.distribution.run_command(command) File "U:/DEV/python-2.7.2/Lib/distutils/dist.py", line 972, in run_command cmd_obj.run() File "U:/DEV/python-2.7.2/Lib/distutils/command/build_ext.py", line 340, in run self.build_extensions() File "./setup.py", line 152, in build_extensions missing = self.detect_modules() File "./setup.py", line 1154, in detect_modules for arg in sysconfig.get_config_var("CONFIG_ARGS").split()] AttributeError: 'NoneType' object has no attribute 'split' make: *** [sharedmods] Error 1 Any suggestions? A google showed a similar error on AIX with no clear resolution. Thanks in advance, Paul
