Software News   Software News : GNU diffutils 2.8.7 is ready for download
   posted by hnl_dk on 2-Feb-2006 13:03:50 (2201 reads)
This is the Amiga (clib2 - linunix) version of diffutils - http://www.gnu.org/software/diffutils/

You can use the diff command to show differences between two files, or each corresponding file in two directories.
You can use the cmp command to show the offsets and line numbers where two files differ.
You can use the diff3 command to show differences among three files.
You can use the sdiff command to merge two files interactively.


Please repport everything You find strage, or would like to get changed to hnl_dk@amigaos.dk.

The archive can soon be found on AmigaOS.dk, OS4Detpot.net and aminet.net

Best regards,
hnl_dk - Henning Nielsen Lund

oops... it is 2.8.7 and not 2.8.6

it is using *nix path style... so if You want to use Amiga path style instead, should you use the one ported by nicomen...
But You should use this one, if You want confiugre scripts to be able to make use of it...

@elwood

Think I shouldn't be coding at the moment, when I am not even able to write the right number

It apears to work with absolute amiga paths.

and even better it doesn't report out of memory for identical files, something that the previous version i'd downloaded did.

Thanks!

Hi,

Thank you for your wonderful job.

I'm trying to compile Web2C (TeX and LaTeX implementation). I mamaged to configure the makefiles. However, at compilation, the compiler tries to use WIN32 specific lines of the code (#ifdef) and gives me errors about memory allocation funtion types!! I Tried --host=powerpc-unknown-amigaos and --host=ppc-amigaos with no avail. Also, adding -D__AMIGA__ to the compiler options didn't help.

Any pointers would be appreciated.

Firbodi

Don't forget Stefans excellent gdiff for a nice graphical front end. Haven't tried it with this version of diff yet, but it should work if the command line is the same.

Funny thing... looks like my fix (is in the cvs) for clib2 worked better than I had hoped
So for the future, should we be able to remove our wrapper functions for abc-shell... I am going to test later today

Cool

It is using *nix path style, and as Andy just told, does it also work with absolute Amiga paths. Will try to see if gdiff is working with it

I think that's something nicomen and olsen fixed in clib2.

@firbodi

I guess that You are crosscompiling on Win32?
Some configure scripts do not work with crosscompilers... You should try using abc-shell on AmigaOS directly

And yes, You should use --host=ppc-amigaos when crosscompiling

@Mr_Capehill

It didn't work before Olaf applied my patch, but I don't know if it had been intended to work before

@Mr_Capehill

Ahh, I thought You where refering to the use of both Amiga and Unix paths
Sorry, if You are talking about the memory issue, do I think that You are right

PS: I see that my path patch is not yet in the cvs, but I hope it gets there soon... If anyone needs it, please send me a mail.

If You are configuring on OS4, then You shouldn't make use of --host at all ... everyting should be done automaticly... all I do, when I configure:

LIBS="-lunix" ./configure --prefix=/SDK/Local --bindir=/SDK/Local/C

or

./configure --prefix=/SDK/Local --bindir=/SDK/Local/C

but always first do a:

./configure --help

to be sure that You don't want to change anything (You might want to add something to LIBS, or use CFLAGS, LDFALGS or some other variables).

That was caused by clib2's implementation choice for calloc(), malloc() and realloc().

According to the almighty ISO/ANSI C and C++ standards:
Quote:
If the size of the space requested is zero, the behavior is implementation defined: either a null pointer is returned, or the behavior is as if the size were some nonzero value, except that the returned pointer shall not be used to access an object.


POSIX states the same thing as ISO by the way.

Of course it turns out these tools assume a zero size means return a pointer instead of a null pointer. So for maximum compatibility, clib2 now uses the non-null for zero size behaviour when linked with -lunix and will assume the original null for zero size behaviour when used without -lunix. Since ISO didn't take a stand on this issue we are stuck with code out there that may assume one behaviour or the other so consider yourself warned.

By the way, newlib.library seems to support only the non-null for zero size behaviour.

Amen! to the "out-of-memory" message.

Now that ssolie has explained it, I have peace of mind (and forgiveness to all). :^) to use emoticons while they are still royalty free.
