gnu on solaris

[Nathan Sidwell]

Hi,
Unless I'm building things stupidly, current gnu tools seem awkward &|
unusable on sparc-solaris. This is a convergence of binutils/gcc/gdb
issues, and I'd like to check that it's not just me,
I tested this on sparc-sun-solaris2.8

1) binutils 2.13 can't build shared objects - well, it builds them
but they segfault. This manifested as an immediate segfault in c++
programs compiled by a subsequently built g++. binutils tests
passed (IIRC). This took a little tracking, and of course the obvious
suspect (the new compiler) was innocent.

2) config & building required
	CONFIG_SHELL=/bin/bash SHELL=/bin/bash ../gcc/configure ...
	make CONFIG_SHELL=/bin/bash SHELL=/bin/bash bootstrap
without telling make, the build forgets partway through that I said use
bash, not sh, and went back to using /bin/sh in a place where it fails.

3) gdb 5.2 & 5.2.1 couldn't read some 3.3pre core files. this seemed a
bit flakey, but on a 3.2 generated core, gdb went into some kind of
infinite loop requiring a kill -9. gdb 5.0 was ok, but has problems
with C++ structures (it thinks many of them are incomplete)

the current install.texi file does not document these issues.

Same here -- while a bit different: it can't find some symbols (which
are actually defined).  I tried CVS version (2.13.90 from last August)
which seems to work.

(I bet there are related to DWARF info, right?).  Again here, I
switched to CVS version.

:-(

I don't know if you have the patience for trying CVS versions for some
of those tools -- it IS sad GCC should require CVS versions of
fundamental tools.

Good luck.

It's probably the now-default "-z combreloc", discussed on the
binutils mailing list.

Fixed in cvs.  Update or revert to 2.12.

I've never had a problem with this.

You'll have to work with the gdb folk with that.

Because they're not intentional?
