[parisc-linux] what i did on my holidays

[Matthew Wilcox]

i've been hacking on various random things; i don't have sufficient time
to commit everything properly (so i'll do it when i get back on monday),
but the curious can look at `all.diff2' in my homedir on pehc.  here's
a rough contents of the diff (in no particular order):

 * changes in support of card-mode dino
 * random spelling mstakes, documentation updates, etc
 * misc cleanups
 * convert ccio-rm-dma to the parisc_device interface.  it was annoying me.
 * change a lot of `void *' to `unsigned long' and remove casts.
 * rationalise function names & user messages

And much much more!

I haven't even tried compiling it since fixing up the cvs merge conflicts
with all the good work done in the last week or so.  Have fun...

You da best! :)

I've been hacking glibc 2.2.4-1:

	- ./sysdeps/ia64/dl-fptr.c changes for try_lock
	- Put change back into dpatch
	
	- Combing through glibc trying to understand the various
	  changes that have been made (and how glibc works).

	- dpkg-buildpackage now makes it to the point of using a new
	  ld.so.1, which seg's... so I'm back to figuring out why.

I'm still not as far as you've gotten. I can't even get within arms
reach of running zic, though I'm getting closer.

Trying to document those g++ problems with #define _BSD_SOURCE that
Zimmerman has been trying to assign blame for ;)

I constantly mull over writing a new "building the toolchain" for
the website.

Then I listen to Tom Waits, and I just feel like drinking and pondering
if my 715/50 really loves me ;)

Excellent.

Yes.  If you decode that long command, it's probably running zic -- that's
the first thing it attempts to build natively.

By the way, there's glibc 2.2.4-2 out now; I don't know what changes
BenC made to it.  In any case, I thought we'd decided the problem was
with a bogus C compiler (since 2.2.3-9 now fails to build).  Any update
on getting a compiler which fixes this?

No, I never get as far as making zic.

Is the last I see. And I'm pretty confused by _what_ is's really trying to do.
It's calling ld.so.1? Or is this just really ld? I wigged out the first time
I saw it fail here. I've seen many weird things, but the internals of glibc are
_really_ wired.

Out of curiosity, is there a gdb package built for debian-hppa?
(Last I checked there was none)

I'll try to debug this on the weekend.
Though my 712/60 has just gone dead on serial and ssh :}

---

I'll give glibc-2.2.4-2 a shot, and see what the difference are.
I assume that -2 is on the debian pool already.

Who is BenC? :)
Is he making general glibc changes or hppa specific ones?

Who's working on the compiler for parisc?

c.

There's an unofficial package in

ftp://puffin.external.hp.com/pub/parisc/binaries/debian/unofficial-debs

pehc cvs needs to be synced up with upstream before the changes can be sent 
upstream and also put in the official Debian package.

No one. Alan Modra periodically does cvs merges and I use that to generate 
patches for the Debian package. We need to catch up with the 
3.0.2ds2-0pre010922 version of the package, which I hope to do next week. That 
might help glibc but I'm betting whatever's causing the build failure it still 
out there.
