Trunk build problems

Trunk build problems

[Nick Kelsey]

Hi guys,

I think its time for a gripe as the trunk has been going downhill rapidly
over the last week or so.

<gripe>

Things I have noticed over the last week:

- Configure in src doesn't do any sub directories any more (linux or
cygwin).

- Under cygwin, libtermcap attempts to be build (which doesn't exist). This
causes a circular make problem as it can't change into the directory so does
a make in src again.

- If you do an incremental make in src it reconfigures a number of
directories *every time* (both linux and cygwin).

- Readline doesn't link under cygwin.

My snapshot from about 2 weeks ago works fine - these are all new problems.

I am interested if these are known problems and under active investigation.

</gripe>

Thanks

Nick

They will be configured when you run make.  This is not a problem.  If
they aren't being, then it is a problem.

Don't know about this one.  Sounds like there's an incorrect dependency
somewhere.

This is a problem.  I sent Nathanael mail about it yesterday, again.

The last one must be new with the 4.3 merge...

Can you show the errors you get? Surely this is because of the new
readline import. Also the configure line, please.

This (as I've come to learn and respect) is a long overdue feature. 
Once you've got over the initial shock (it took me a week ...) it really 
is much much better.

- It no longer configures directories that are not needed - huge time saver!

- It can parallize configures

Sounds like Makefile.tpl (?) needs a tweak?

One case of this - bfd - was fixed.  Is this another case?

Readline was finally updated.  Again, very long overdue.  If there are 
problems, then please report them (hopefully with fixes).

I suspect that they are unknown (I didn't know about them).

If you're wondering these changes are occuring now so that, hopefully, 
there is plenty of time to catch problems such as you are finding before 
the next GDB/binutils release.

BTW, the place to report each problem is gcc@gcc.gnu.org (cc'd 
gdb-patches@).

Also, it doesn't even list those directories in the Makefile, so we
don't waste time checking - repeatedly - to see if they're configured.

More accurately, it can configure one module while it starts building
another.  We can't actually do two configures at the same time because
of the shared cache.

Yup.  It should at least be "cd foo && make" not "cd foo; make", but a
make:configure dependency might be missing too.  Nate?

Nate's working on a fix to cover all of them.  After that, we can
worry about missed ones.

I have made what I hope is an obvious change to config/mh-cygwin.  I can
build gdb now.

>- Readline doesn't link under cygwin.

Elena pointed me at the proper file to fix for readline so I just checked in
a fix.

I just wanted to clarify that this only affects building readline for a cygwin
targeted cross build.  This was broken (in a minor way) by the recent readline
import.

                 ^^^^^^^^^^^^^^^^

An obvious problem for cygwin.

I've checked in a patch to fix this behavior, after consultation with
Elena.  It will require rerunning configure in the readline directory
to turn off shared library builds.

Rrrrm.  I'll see if I can track that one down, it's new to me.

Hi all,

Thanks for the fixes... everything is working well.

Very happy.

Hi guys,

I think its time for a gripe as the trunk has been going downhill rapidly
over the last week or so.

<gripe>

Things I have noticed over the last week:

- Configure in src doesn't do any sub directories any more (linux or

- Under cygwin, libtermcap attempts to be build (which doesn't exist). This
causes a circular make problem as it can't change into the directory so does

- If you do an incremental make in src it reconfigures a number of

- Readline doesn't link under cygwin.

My snapshot from about 2 weeks ago works fine - these are all new problems.

I am interested if these are known problems and under active investigation.
