[orbitcpp-list] compiler issues

[Phil d. <ph...@us...>]

Hi Andreas & everyone,

The orbitcpp compiler is a bolt-on to the orbit-idl compiler. I have a
couple of questions:

1) Currently you must install the plugin C++ backend library before you
can use the compiler. Is there anyway around this?
Ideally I'd like to be able to run the compiler with the library in the
build directory so that the tests can be run without installing the
compiler. (Otherwise this will break nifty things like make distcheck)
Do I have to patch the orbit-idl compiler to supply a backend directory
as an argument?

2) Currently you must issue 2 commands to generate the stubs/skels:
	orbit -l c blah.idl
	orbit -l c++ blah.idl
How easy is it to integrate the call to the C compiler into the C++
backend, thus reducing it to
	orbit -l c++ blah.idl

Cheers,

Phil.

at least. but libtool won't make your job that easy.
(you might try libtool --mode=execute ...)

i asked elliot about this. currently, we would either have to duplicate
code (10 lines or so) from orbit-idl or patch it to make those calls
easier. neither seems worth the trouble, since they consider their
backend interface "rather a joke". i believe we should go with the two
commands until they rewrite their compiler.
