Hello Again!
It never rains but it pours.... ;-)
Well it wasn't going to be long before I got back to programming after
getting the PPC card. Now that I have the said card, I decided to install
VBCC 0.7 for PowerUP and WarpOS. I had been using the 0.7 release of VBCC
for the 68K very successfully for the past year or so, and release 0.6 or
something before that for a year or more. Now that I have a PPC, developing
some useful PPC apps is one of my aims... well it was... ;-)
Firstly, I have been using VBCC PuP with just the standard ANSI C include
files successfully. I have been building some string processing code
(pointers and all that), and compiling PuP ELF files as a result and they
have all worked great. However, my projects require some Amiga functions;
namely from graphics.library, exec.library, intuition.library and
gadtools.library - oh and diskfont.library :-). So as I did for VBCC 68K; I
instaled the 3.1 includes into /vbcc_ppc/machines/amiga/includes// and then
knocked up a quick intuition opening a window, and simple IDCMP CloseWindow
event. The only difference is that the Window structure was made an array
to hold five instances; which is not of interest since that isn't the
problem.
Like I say, I have been compiling my ANSI stuff using: (after executing
'init_vbcc'):
vc +ppc hd1:c_code/hcl/hcl_string.c -o hd1:c_code/exe/hcl-string.elf
That works fine. However if I compile that code with Amiga specifics, using
both PuP and WOS using:
vc +ppc -amiga-align hd1:c_code/native/test.c -o ram:test-win.elf
OR
vc +warpos -amiga-align hd1:c_code/native/test.c -o ram:test-win.exe
I get errors in the linking stage with 'vlink' and it complains about
undefined references to the AmigaOS functions I have used (OpenLibrary,
OpenWindow, WaitPort, CloseWindow, CloseLibrary), and quits. Compiling
with a 68K target (ie: using VBCC 680x0) - the code compiles perfectly with
no errors or warns. And of course the code works 100%
Now can anyone help me here? I re-iterate that I am using the init_vbcc
script; and that it has compiled ANSI non AmigaOS extensions code fine.
All the best,
Nick.
