Why not compile both and let the user be the final judge of what he want.
With a clever done diversions tuff, i guess the package maintainer could
strongly hint at one solution he consider best, but leave the user the
possibility to override this, possibly with a debconf dialog or something
True, this makes a bit more work for the packager, and may not be worth it for
some packages (especially the really big ones, like maybe coq), but you can
not think of al the possibilities that can cause the user to choose one or the
other. Imagine a new shiny i386 processor, for which the shipping ocaml has a
broken native code, or something such other unlikely.
That said, compiling the bytecode with -custom for arches without native code
solution is a nice idea i had'nt thought off :)))
BTW, you would need to depend on the ocalk-base package, but also on the
shared stubs libraries of all the non pure ocaml packages you depend on. Maybe
in this case, the -base postfix was ill choosen, or we should split off
libraries with -runtime or something such, including the shared libraries
needed for them.
Also, am i right in thinking that all the shared stub libraries in the ocaml
package got named dllxxx.so ?
They are :
dllbigarray.so dllgraphics.so dllmldbm.so dllnums.so dllstr.so
dllthreads.so dllunix.so and labltk/dlllabltk41.so
And need to be included in the ocaml-base packages .
Does someone know what an rpath is , and if i trully have to worry about the
lintian warnnng about them ?
