building egcs under LinuxPPC pre-R5

building egcs under LinuxPPC pre-R5

[Andreas Tobler]

Hello,

since the beginning of February I try to build egcs snapshot 19990131
and now 19990208. The succcess is small. I got the 19990131 snapshot to
build and install, but when I compile c++ code with some include
restrictions it seems that it overrides it which causes an error. The
egcs I used before and now again, was 2.91.60 I think, for LinuxPPC
folks egcs-1.1.1.1c. With this compiler I haven't had this error.
My question, is there something specific when building an egcs on
LinuxPPC that I have to take care of? It's not necessary for me to take
a snapshot, but I need to build an egcs & libstdc++ with the option
-fno-vtable-thunks.

my config: 	LinuxPPC pre-R5 with glibc-2.0.108
		Kernel 2.2.0 self built
		running compiler egcs-1.1.1.1c
How I did egcs:	./configure --enable-shared --enable-threads
--prefix=/usr/local/egcs
		make LANGUAGES="c c++"
		make LANGUAGES="c c++" install
Any hints?
Thanks

Andreas

The latest snapshots are very unstable on Linux/PPC.  We are working on
this now, but I'd stay away from them until further notice.

The version of EGCS-1.1.1c that I uploaded should have been compiled this
way.  What makes you think it was not?

He's probably talking about the pre-R5 egcs-1.1.1-1c RPM's which I prepared
for the R5 distribution. They have vtable-thunks enabled, as it is the
default for glibc-2.1 based egcs.
Gary, if you are producing RPM's for R5 which have vtable-thunks disabled,
I hope you are using versioning to distinguish the binary incompatible
libstdc++ stuff.

I would also appreciate if someone knowledgeable would document
(history/future, pros/cons, etc.) the whole vtable-thunks/no-vtable-thunks
stuff and put it in the FAQ.html (or a separate vtable.html?), cause
searching the mailinglists reveals 140 :-) documents on this issue.

Franz.

Yes I'm talking about the pre-R5 RPMS which I got from biggi.linuxppc.org on
the 4.1.99.

Franz,
is it possible to get your SRPM of this egcs? So I can do a build by myself.

Thanks
Andreas

No, I was only talking about the GLIBC-1.99 version.  This only reinforces
the problems we are encountering wrt GLIBC versions and the differences
that they imply.
