digitalmars.D - Programming Be with D

Would D be an ample and adequate alternative to programming for the BeOS
classes? What are the pitfalls I may encounter?  Advantages?

For a brief tutorial on the BeOS classes, etc. look here:

Please take a look!

Thanks!

The topic of using BeOS has been mentioned in the D community 
previously. I've pasted some excerpts of posts from Matt (a/k/a "me") 
that might be help.

 From http://www.digitalmars.com/drn-bin/wwwnews?D.gnu/701:

I'd love to port the D gcc compiler to BeOS for intel, but unfortunately
BeOS uses gcc2.95. Because the whole OS is C++ based, gcc3.x is a 
pointless thing to have (and no one has really attempted to get it 
working for the OS), and so gcc2.95 is what we're stuck at. Just to put 
me out of my misery, how completely impossible would a 2.95 port be?

TIA

Matt



 From http://www.digitalmars.com/drn-bin/wwwnews?digitalmars.D/4745:

Okay, so I've ported DLI (latest version I could source on the 'Net) to 
BeOS (well Zeta RC3, but same difference.) This was no mean feat as 
there is some funky Linux specific code in it, I also struggled slightly 
with compilers (as BeOS has a limited set of options.) Phobos is a 
static lib rather than a shared one (as this didn't want to work - 
getting Phobos to compile at all meant a lot of hoop jumping and the 
eventual abandoning of aged makefiles..)

I ported DLI to BeOS (Zeta) and it works. This gives you an extremely
outdated D compiler. I'm not sure how useful it really is ;-)

I'm waiting on the gcc3 port that Ahwaychih is working on. When that
stabilises we could probably build gdc.

Well, C++ is not compatible with D, and so you'd not be able to use any BeOS
GUI API. You'd be in the same position as the FreePascal people. The whole
GUI would need to be wrapped or repackaged in C. Not a small task, believe
me. I've attempted it twice before ;-)
