Dear devs,
I am the maintainer of the QGIS port for the FreeBSD OS.
For some time now I have problems, when running a more recent QGIS devel
version on FreeBSD. QGIS devel does not show and/or let me edit layer's
metadata.
For example, if I have a vector layer and go to
[Layer Properties] -> [Style] -> [Fill] -> [Simple fill]
all I get in the [Symbol layer type] area is
[This layer doesn't have any editable properties]
The corresponding debug messages seem to be the following:

[..snip..]
This is on FreeBSD 11.0-CURRENT with clang compiler 3.8.0 and cmake
3.5.2. QGIS is on Git tag #1563526, so the patch for 'Simpler handling
of DLL_EXPORT defines' #d3fd818 is already included.
The debug messages point into the directions of a casting problem.
I am not a programmer, but to me it seems, that there is a problem with
the visibility of some layer properties code. Before #d3fd818, I was
able to see the layer's metadata, if I built QGIS with commenting out
the following line in all CMakeLists.txt files:
#SET(CMAKE_CXX_FLAGS "$${CMAKE_CXX_FLAGS} -fvisibility=hidden
-fvisibility-inlines-hidden
Unfortunately, I have no idea, what to do next :(
I would really appreciate any help or hint in this context. Please let
me know, if I should provide more information or test something.
Many thanks in advance,
Rainer Hurling
