A C compiler that can compile for dragon 32?

[lukeoftheaura]

Hi,
is there a C compiler available (for linux preferably) that can compile for the dragon 32?

Thanks,
luke

Hi Luke!

Maybe gcc 6809 is what you're looking for.

Cheers,
Rob

Also, Pierre Sarrazin has developed a 6809-generating cross-compiler for a subset of the C language.

http://perso.b2b2c.ca/~sarrazip/dev/cmoc.html

The website says `The most significant difference between CMOC and a complete C compiler is the absence of longs and floats and of the const keyword.'

I'm not very knowledgable about such things but thought I'd post a link in case it was of interest?

Of course it's of interest!

I've tried a couple of times to compile gcc6809 without luck, so maybe this one will come in handy.

Thanks, mate!

I'll certainly give this a look - compiling gcc6809 seems like a bit of a pain.I wonder if there's a graphics library?

I know CMOC supports inline assembly language. Handy I guess for sections of code which are speed critical.

I think Rick Adams wrote `Temple of Rom' using a mix of C and ASM?

So far I've managed to write the classic "Hello world" program using CMOC and run it on xroar and I'm quite impressed, but I don't know how to then convert that so I can run it on real hardware (to cas or WAV). any ideas?

I use `Bin2Cas'.

I can't seem to make bin2cas work, there's probably an option I'm missing.
I have this program:

Code: Select all

#include <cmoc.h>
int main()
{
    printf("HELLO WORLD!\n");
    return 0;
}

I compile it using

Code: Select all

cmoc main.c

and when I open the bin with xroar, I get the expected output. Then, I run bin2cas to convert to a cas file, and cas2wav to convert to cas:

Code: Select all

./bin2cas.pl main.bin -omain.cas
./cas2wav main.cas main.wav

Then when I open the wav or the cas in xroar it seems to load the file but then nothing happens (it stays on the screen saying "F MAIN"), and I get the same response when I load it on my dragon 32.

Hi Luke,

Try my DrBinCas program which you can find here.

Tell me if you have any problem with it.
