Re: PING: Patch: mainline bootstrap failure (libobjc)

[Matthias Klose]

The first part of the patch is wrong or at least incomplete. Adding
-I$(srcdir)/$(MULTISRCTOP)../boehm-gc/include helps for compilation
only, it misses linking of the boehm-gc and installation of headers
and libraries.

If using the included boehm-gc is correct at all, is another
question. See the thread starting at

	http://gcc.gnu.org/ml/gcc/2001-01/msg01019.html

The patch to libobjc/gc.c seems to be a workaround. At least it seems
to fix the errors seen in

	http://gcc.gnu.org/ml/gcc/2003-01/msg00007.html

Well, *that* change
1. needs more knowledge about gcc's build machinery *and* boehm-gc than I  
currently have
2. seems as if it would certainly need an assignment from the patch author

so I can't do that one, at least not right now.

In the mean time, the current patch *does* at least help the compilation.

That's what it's for. It's entirely along the same lines as a similar  
patch by Zack a while back ... ah yes, thread starting with
http://gcc.gnu.org/ml/gcc/2002-12/msg00023.html; I believe any fix for  
that one should also fix this one. From readinmg that thread, it seems gcc  
needs to have a way to pass down some properties of the target to the  
library. It currently hasn't, thus the workaround.

All this makes me wonder how --with-objc-gc ever made it into gcc. It  
seems rather untested.

PING: Patch: mainline bootstrap failure (libobjc)

[Kai Henningsen]

Bootstrap failure: http://gcc.gnu.org/ml/gcc/2003-01/msg01128.html
Patch to fix it:   http://gcc.gnu.org/ml/gcc-patches/2003-01/msg02061.html

I believe the problem is actually present on all branches.

Any kind of feedback that gets this closer to resolution is welcome.

Kai
