version.sh has some non-portable constructs
nimaimalle
From the source code, the version.sh file needed a few changes to make it work on Mac.
First, the method of deriving the patch number from git needs to trim leading white space.
Before, After:
git log --pretty=oneline 2>/dev/null | wc -l
git log --pretty=oneline 2>/dev/null | wc -l | tr -d ' '
Second, echo -n is not portable across linux versions. To achieve output without a new-line, use printf instead.
Before, After:
echo -n "${VERSION}.${VERSION_PATCH}" |sed s/M//
printf "${VERSION}.${VERSION_PATCH}"
I'm not sure what the sed s/M// was for, but maybe it had to do with the svn codepath, which I did not test.
