Subject: Don't use "readlink -e" in docs generation script, it's not portable.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/ee6e22d94cd07fbe4bf522603c17546514c6934d?ds=inline

Don't use "readlink -e" in docs generation script, it's not portable.

"readlink" command also exists under OS X but with a completely different
syntax than under Linux, so just use "pwd -P" to get the physical path name
instead, this should hopefully work everywhere as it's POSIX.

Closes #14796.
