Message 260595 - Python tracker (original) (raw)

Tamás, it might be a good idea for you to sign a contributor agreement <https://www.python.org/psf/contrib/contrib-form/>.

I compiled Python in 32-bit mode and tried your v2 patch out, which found the wrong library as I predicted. Then I tried your new regex and it picked out the correct line. I had to edit it to get it to extract just the filename from the line:

r'lib%s.[^\s]+\s(%s(?:,\s.)?)\s=>\s(.)' % (re.escape(name), abi_type)

I factored out the closing bracket from the comma + space bit, moved the group brackets to the end to extract the filename, and made it a raw string.

Without the patch, in 32-bit mode it will find 64-bit-only libraries:

find_library("m") # 32- and 64-bit available 'libm.so.6' find_library("tcl8.6") # Only 64-bit version available! 'libtcl8.6.so'

With my edited regex:

find_library("m") '/usr/lib32/libm.so.6' find_library("tcl8.6") is None # No 32-bit version found True
