           Summary: configure fails when using a version of GNU Bison
                    built from Git
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: Normal
         Component: common
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: ssssam at gmail.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


I had the following problem configuring master of gstreamer.git:

$ bison --version
/gstreamer.build # bison --version
bison (GNU Bison) 2.7.1.1194-51a4-dirty
...

$ ./configure
...
checking for bison... /usr/bin/bison
checking bison version 2.7.1.1194-51a4 >= 2.4... Bareword found where operator
expected at -e line 1, near "51a4"
    (Missing operator before a4?)
syntax error at -e line 1, near "51a4 "
Execution of -e aborted due to compilation errors.
configure: error: no

This is due to not quoting the string when calling 'perl' to check the version
number. The - sign causes a syntax error. Patch attached which adds quotes to
avoid this problem.
