Hello,
as the problem recently popped up how to load auxillary files in the source
directory that have not been installed to their final paths, I've created a
patch that will add a fallback directory path to get_datafile_dir.
So far get_datafile_dir would check wether some magic variable were set to
locate generated (i.e. compiled) stuff inside the build dir instead of the
install dir. This patch allows to override this behaviour to search in the
specified directory relative to the source dir. If the fallback path is
given as NULL, the previous behaviour is used. As the path may now be
different with different invocations, the caching of the path had to go.
Example call:
WIRESHARK_RUN_FROM_BUILD_DIRECTORY=1 WIRESHARK_SRC_DIR=../trunk ./wireshark
This would solve https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=5664
which would make me quite happy because I rarely build in-source-tree.
But: could it be done automagically? For example, 'configure' sets up
$top_srcdir appropriately; could we somehow get that variable passed
into the libtool script (./wireshark) or...?
I suppose it would not be a good idea to embed $top_srcdir in the
resulting binaries and the libtool script only exists when using auto*,
so I guess your approach does make the most sense.
