It depends. :-(

Which is part of the problem.

Both. :-(

For reasons known only to a certain individual the dmd (and as a knock on
consequence the ldc2) compiler have option structures that are almost, but not
quite, entirely unlike GCC standard options (*). Gdc is fine since it is part
of the GCC suite.

So you have to distinguish dmd/ldc2/ldmd2 on the one hand and gdc/gcc/g++ on
the other, which may necessitate munging options. And some dmd options are
different in ldc2, but not ldmd2.

Moreover the .pc file for a library has options dependent on the compiler
being used to create the library. If you use the same compiler then the
options are right, if you use a different one, you have to munge.

This situation really is a disaster. But one that one must cope with. Either
than or give up, go to a corner, and cry.


(*) With apologies to Douglas Adams for munging his tea from a machine
sentence.
