I'm confused - findentrances doesn't use gpx.h at all, and I don't see
where the makefile "tries to be clever" in the way you describe.

PROJ is now a requirement to build aven though, which it didn't used
to be.

Thanks, added.

That's just in the generated files (they look for the tool they were
generated with, which was automake-1.14 in this case).

The simplest way to retool is:

autoreconf -fiv

Aven's "export as GPX" now provides most of the functionality of
findentrances, but with a lot more flexibility (it can export other
stations and also passages).  The missing part is a nice way to set up
PROJ so it knows what the coordinates mean - in aven you can actually
set this, but you have to edit the aven config by hand and add a
setting like:

input_projection=+proj=tmerc +lat_0=0 +lon_0=13d20 +k=1 +x_0=0 +y_0=-5200000 +ellps=bessel +towgs84=577.326,90.129,463.919,5.137,1.474,5.297,2.4232

If you don't, it assumes the grid CUCC use in Austria.

With findentrances you need to specify that same string, but you can do
it on the command line at least.  So findentrances is mostly just
lingering until that gets sorted out so you can specify this in a
simpler way to aven.

It looks like wxGTK3 should itself depend on wxBase3, so am I right to
think that the spec file should read like so:

BuildRequires: wxGTK3-devel, proj-devel
Requires: wxGTK3

Or something else?
