configure fails when using bash 3.1.x
-------------------------------------
Key: MODPYTHON-122
URL: http://issues.apache.org/jira/browse/MODPYTHON-122
Project: mod_python
Type: Bug
Components: core
Versions: 3.1.4, 3.2
Environment: Any platform using bash 3.1.x
Reporter: Jim Gallacher
Assigned to: Jim Gallacher
Priority: Minor
A bug in bash 3.1 causes configure to fail. This has been report on recent
versions of Gentoo and and deicussed on the mod_python mailing list:
http://bugs.gentoo.org/show_bug.cgi?id=118948
http://www.modpython.org/pipermail/mod_python/2006-January/019965.html
http://www.modpython.org/pipermail/mod_python/2006-January/019969.html
According to the gentoo bug report, the problem in configure.in is the double
backslash escape sequence in the line:
MP_VERSION=`echo $MP_VERSION | sed s/\\"//g`
Changing this to:
MP_VERSION=`echo $MP_VERSION | sed s/\"//g`
fixes it for bash 3.1.
I wonder why we are using \\" since the gentoo fix seems to work ok with bash
3.0 (and GNU sed) on my system just as well. Is it there to support other
shells, other sed versions, older bash versions... ??
I suggest we either adopt the gentoo fix, or avoid the problem altogether by
using tr. eg.
MP_VERSION=`echo $MP_VERSION | tr -d '"'`
