[Notion-devel] Questions on portability and quick-n-ugly simple fix for NetBSD

[Silas S. <si...@gm...>]

Hi there.

notion is a great continuation of ion3, and much more democratic  :-)

I'd like to ask you how you deal with portability.  Is Linux the main
target?  Is it the only target?

I've successfully compiled and used notion in NetBSD, with no problems,
but recently I had to make a one-line modification to workaround a
problem... patch is attached.

So, do you plan to work on portability?

Thanks.

There's no patch attached.

As far as I'm concerned, which only counts a certain amount, any
reasonable changes needed to handle portability are worth it.

Given the needs of notion there really shouldn't be too much that causes
portability headaches.

Yes

No: a while ago we fixed some problems to build have notion build properly on 
solaris, for example

Cool

No it isn't :)

Personally, not really, but if you can test things and provide patches I'd be 
happy to consider them for inclusion. 


Kind regards,

Sorry, here we go with patch _attached_ now!!! :-)

This is quick and ugly.  There might be a more inteligent way of doing
this besides poluting code with #ifdefs...

What problem does that fix exactly?

features.h doesn't exist in NetBSD and maybe in other BSD platforms.

#include <features.h> is really necessary in Linux?  I even don't know
what functionality it includes...

Does '#include <sys/featuretest.h>' work?

It works and it is a much better solution, thanks!!!

Have conditional compilation to differentiate OS/machines is ugly.
Stickying to ANSI C is much better and it is why Lua is so portable :-)

Thank you very much.

Ok, good. Now I just need to find out what defines I can use to detect
netbsd.

Yeah, when it is reasonably possible being natively portable is definitely
the best option. But the farther up the stack you get the less that's
really possible (well up to a certain point at least).
