For GraphicsMagick I need to maintain a GraphicsMagick-config script
which contains such things as the list of libraries necessary to link.
The conditionally installed libltdl seems to make this difficult to
If enable_ltdl_convenience is 'yes' then it is wrong to list -lltdl as
needed but if enable_ltdl_install is 'yes' and enable_ltdl_convenience
is 'no, then it appears that -lltdl should be listed as a dependency.
In GraphicsMagick things are even more confusing since for a static
build, libltdl is not used at all.
It is necessary to build this logic out of internal configure
variables. A bunch of existing substitutions will need to change in
scripts and Makefiles. Ugh!
It seems that the GM 1.2 release is a bit botched since I did not take
the time to think through the convoluted logic.
I suspect that other packages will be bit by this as well.
