Looking for C library "bbc.h"

Does anyone know where to get hold of this library please. Several listings I’m looking at call for “bbc.h” to be ‘#include’d but it isn’t provided within my copy of AcornC/C++ and I can’t find any sensible reference searching the internet. Or is it known as something different nowadays?

Thanks.
Chris.

Is it not a part of RISC_OSLib (not CLib)?

Update: sorry it IS there in AcornC/C++.Libraries.RISC_OSLib
does this mean it’s only commercially available and people using GCC wouldn’t be able to get a free copy?
thanks
C

Does GCC load AOF libraries still?

I may be wrong, but I seem to recall DeskLib having a similar set of routines. My version for AOF, or the GCCSDK version for AOF (old) / ELF (new).

Okay. At home now. (^_^)

You may be able to find/build a copy of RISC_OSLib separate from the DDE. I’m looking at “bbc.h” and it is covered by the Castle licence applied to the open source code. At least, if it is the “bbc” stuff you want, you ought to be able to pick up the pieces from the source repository and roll your own mini-library.

RISC_OSLib is rather badly put together – it’s all one source file, so if you only want bbc_inkey(), for example, you’re obliged to have all the other stuff as well.

Or…

There is not an exact match for the BBC library in DeskLib. It depends what you want to do.

For drawing (bbc_plot(), bbc_rectangle(), etc) – take a look at the GFX header in DeskLib. It doesn’t cover everything (like bbc_gwindow()) because it is aimed at using the graphics primitives within desktop programs (so the Wimp will already have defined the graphics window).
If there is a need for additional things, I’ll be happy to add them to my version of DeskLib, however note that most of the graphics commands in RISC_OSLib are simply calling bbc_vdu() a bunch of times, so with that in mind, anything necessary can easily be faked. Perhaps even with a simple preprocessor macro?

For sound, there is only a “beep” in DeskLib. Looking at RISC_OSLib, all it is doing for the additional functionality is calling os_swix() for the Sound SWIs. I’m not sure I see the point. Maybe turning the sound on and off and setting the voice channels seemed like a good idea back in the days of Arthur…

That leaves bbc_adval() for which no equivalent exists (and if it did, it would probably be a dedicated function to return buffer information through DeviceFS or the like and not OS_Byte calls), and bbc_inkey() which is exactly Kbd_KeyDown() – and it returns the commonly expected 0 or 1, not 0 or -1 like RISC_OSLib (a hangover from BASIC?).

Thanks for all that Rick – I’ll take a look at DeskLib, also I found OSLib at http://ro-oslib.sourceforge.net/release-7.00.html
Now, I notice within the bbc.h library it does a #include os.h
I’ve been trying to use the bbc.h library within my copy of Acorn C/C++. Here is my trivial C program – just to change mode (testing out the bbc.h library):

#include “bbc.h”
{
int main (void)
bbc_mode(7);
return 0;
}

The !SetPaths app sets up RISC_OSLib$Path to point to SDFS::16GbPi.$.Programming. AcornC/C++.!SetPaths.^.Libraries.RISC_OSLib.
(where bbc.h and os.h live)
And I am using cc -i<RISC_OSLib$Path> prog.c to compile the C program

But it’s throwing up Serious error: #include file “os.h” wouldn’t open. What am I doing wrong please?

thanks

It’s a while since I’ve used c from the command line – it’s easier to use the !cc app for small tests but

cc -IC:,RISCOSLib: -LC:o.stubs,riscoslib:o.risc_oslib prog.c

should work.

I tend to use shared makefiles, in which case you can add -IRISCOSLib: to CINCLUDES (for the compiler) and ${RLIB} to LIBS (for the linker).

#include "bbc.h"

int main (void)
{
bbc_mode(7);
return 0;
}

This works :-

*cc -IC:,risc_oslib: -LC:o.stubs,risc_oslib:o.risc_oslib prog.c
