This feature is available in all versions of 1.10 and all later branches. +Why do I get a SyntaxError when I run configure.py? +---------------------------------------------------- + +The ``configure.py`` script in 1.10 and later versions requires Python +2.6 or higher. In Python 3 the exception catching syntax changed, and +while 2.6 and 2.7 understand both syntaxes, 2.5 does not. If you see +an error like this:: + + File "./configure.py", line 62 + except OSError as e: + ^ + SyntaxError: invalid syntax + +Then you are using Python 2.5 (or earlier). For Python 2.5, a Perl +one liner can fix the syntax:: + + perl -pi -e "s/except (.*) as (.*):/except $1, $2:/g" configure.py + +or in Python:: + + import re + + lines = re.sub(r"except (.*) as (.*):", r"except \1, \2:", + "".join(open("configure.py").readlines())) + open("configure.py", "w").write(lines) + +However Python 2.4 is missing a number of features and cannot be used +to configure the build in 1.10; you'll need to upgrade to at least 2.5 +(or preferably 2.7 or 3.1). + The self-test program can't locate the library ----------------------------------------------- |
