Description
I have built Python 2.6 and 2.7 with +universal. I need to execute 32-bit Python for a specific module.
tcmac$ file /opt/local/bin/python2.* /opt/local/bin/python2.6: Mach-O universal binary with 2 architectures /opt/local/bin/python2.6 (for architecture x86_64): Mach-O 64-bit executable x86_64 /opt/local/bin/python2.6 (for architecture i386): Mach-O executable i386 /opt/local/bin/python2.6-config: a /opt/local/Library/Frameworks/P script text executable /opt/local/bin/python2.7: Mach-O universal binary with 2 architectures /opt/local/bin/python2.7 (for architecture x86_64): Mach-O 64-bit executable x86_64 /opt/local/bin/python2.7 (for architecture i386): Mach-O executable i386 /opt/local/bin/python2.7-config: a /opt/local/Library/Frameworks/P script text executable
However, when using the arch command to specify the runtime architecture, only Python 2.7 honors this, it does not work with Python 2.6.
