Hi,
while working with the egcs configure scripts on a native powerpc-unknown-linux-gnulibc1 system (see my preliminary patch on < http://homepages.munich.netsurf.de/Franz.Sirl/misc/ppclibc1.diff >), I noticed the following about the make frags:
1. mh-ppcpic is pulled in for host=powerpc-unknown-linux-gnulibc1
2. mt-linux is pulled in for *-*-linux-gnu
3. if shared && powerpc*-*: mt-ppcpic is pulled in and replaces mt-linux
Is this correct for "configure --enable-shared" on glibc2 systems? Shouldn't that be additive?
BTW, for config.guess $(CC-cc) will fail silently on gcc-only systems with no cc symlink. I think configure should try to figure this out.
Bye,
Franz

I have sent this patch long time ago to deal with this. But
noone cares enough to check it out:
Sun Sep 7 14:27:56 1997 H.J. Lu (hjl@gnu.ai.mit.edu)
* configure.in (host_makefile_frag, target_makefile_frag):
Handle multiple config files.
(alpha-*-linux*): Treat alpha-*-linux* as alpha-*-linux* and
alpha-*-*.
Please check out the egcs archive for my patch. My patch should not
hurt anything. It is just modified to deal with the case above. The
Linux/alpha patch is also needed.
BTW, it happens on all linux platforms with PIC.

You submitted that big ugly patch and didn't make any attempt to describe
why it was needed. I told you at the time I had no intention of installing
the patch without such information.
Franz managed to desribe the problem reasonably well in his message, odds
are if you had bothered to take the time to do the same, then this problem
would have been fixed by now.
It's definitely too late to go back and include your patch for the release.
Can we come up with a less intrusive way to fix this problem?
Seems to me that we could add something like this after the alpha/linux
line in the shared case
*-*-linux*) target_makefile_frag=config/mt-${target_cpu}linuxpic
Or something similar. We then need a few linuxpic files.

I asked you directly about that patch. Shall I go back and find the message
and provide an exact quote?

I don't know if there will be a libstdc++2.8
BTW, the problem you're referring to has been fixed. I fixed it a few
days ago.

Doesn't matter. Your patch is _far_ too intrusive to go in at this time;
if you want this problem fixed, find a less intrusive way to address the
problem.

If I were asked directly about that patch, I would have
explained it. But I thought it was quite obvious that
--enable-shared would include the seond config file on
many platforms.
One more thing, will there be a libstdc++ 2.8 for gcc
2.8? If the answer is yes, $(CC) should be used for
making libstdc++.so in libstdc++/Makefile.in, instead
of $(CXX).

I am not sure if it is a good idea. I tend to think it may
cause more trouble than my old patch. The problem happens
when you have more than one config files. In my case, it
is --enable-shared. You don't want linuxpic if --enable-shared
is not used. To do it right, you should support multiple
config files.
BTW, if you take time to have a close look at my patch, you
may find it quite reasonable. My patch just allows multiple
config files.

What will gcc 2.8 use?

Maybe the patch I sent earlier might contain other stuff. Here is
the one which just fixes alpha-*-linux* and multiple config files.
Please take another look. I think it is quite straight forward.
The only thing I did was handle multiple config files.
Thanks.
