#1075 — Libraries for RISC OS

Hello,
I am attempting to learn C on RISC OS. (I have the latest C/C++ tools 
from RISC OS Open)

I've started off with recompiling some existing software, basically to 
learn about how the various tools work.

Currently I'm attempting to recompile Zip 2000 to work on the 
BeagleBoard with allignment exceptions turned on.
I've read the notes in the source code archive for Zip 2000, and it 
requires OSLib 6.21, libpng 1.2.0 & zlib 1.1.3.

I've downloaded the latest OSLib, but I can't find a RISC OS port of 
libpng nor zlib. I've checked the websites for each, but can't find 
anything.

Can someone please point me in the right direction?

Many Thanks,
Rob.

I suspect you might have to download the original sources and then 
fiddle with configure scripts etc. which isn't really much about 
learning C :)

Or check out:

http://www.riscos.info/packages/LibraryDetails.html#ZLib1g-Dev
http://www.riscos.info/packages/LibraryDetails.html#libpng12-dev

which you might have some luck with, but those are GCC-built rather than 
AcornC/C++.

Lib/zlib is mentioned here though - 
http://www.riscosopen.org/content/downloads/risc-os-tarballs/component-list 
, so downloading the relevant source archive may be of help in that respect.

Alex.

Thanks for the links Alex,
I did have a look on www.riscos.info however when I searched for zlib, 
I only got 1 result for 'Using GCCSDK'

I'll have a look at them!

Cheers,
Rob.

Hi Rob, I have been learning with GCC, and it is very common for
libraries to be needed. It is ideal if you can make the libraries
from their sources, though the ones you need are common and may
be available. Have you tried building them?

Hi Ron,
I haven't tried building them, to be honest I didn't think they would 
build! For some reason I was looking for a specific RISC OS version! 
(Not sure why now!)


I'll try building them and post my results back here!

Cheers,
Rob.

Hi Rob

I managed to build both zlib (1.2.5) and png (1.5.1) a couple of
years back using the Castle/Norcroft compiler. It seemed ok, but I
have never used them in anger, so don't know if there are any issues.

If you want copies to have a play with, let me know. Not sure if it
was compiled BB friendly though.

Hi Chris,
That would be great if you could send them over!
I'll try them on the BeagleBoard.

Many Thanks!
Rob.

Have sent off the two libs (png and zlib) direct. If you have
problems with recompiling (if you need to) I could always recompile
with BB friendly settings.

I've got both of these that'll compile with Acorn C, drop me an email if
you want a copy.

Hi Rik,
If you could send them over, that would be great!

Thanks,

Thanks to Rik Griffin & Chris Johnson, I have sucessfully compiled 
zlib and libpng on the BeagleBoard.

Cheers Guys!
