Hi all,
I did get around this issue by not trying to use the Cray CC and cc
commands. They must do something that skews how the whole scenario is
supposed to work
By just using the PrgEnv-gnu module and using gcc and g++ directly, I do
not see the issues outlined below. The proper libstdc++ library that is
associated with the gcc and g++ version is used.
Thanks,
Jim G

Hi,
I'm building our OpenSpeedShop performance tool to run on the backend
nodes of a Cray-XE machine. We use the libtool, m4, autoconf, and
automake autotools.
Everything is working accept I'm getting the wrong libstdc++ library
when linking the main program that runs on the backend nodes. Each
of the libraries that I'm building that get linked into the main
program have /usr/lib64/libstdc++.la in there .la files. The
/usr/lib64/libstdc++.la isn't the one that corresponds to the
/opt/gcc/4.6.1/bin/g++ compiler that I'm using to build for the target
(Cray backend nodes). This compiler has its own stdc++.la file:
/opt/gcc/default/snos/lib64/libstdc++.la.
I'm not sure how resolve this and have spent a few hours trying to
find how to force the build of our tool to use the correct version of
libstdc++. The host version and the target version conflict and
cause linker errors when building the main program.
I'm guessing I'm doing something dumb.
I build my own libtool, autoconf, m4, and automake because the ones on
the Cray frontend node are old (libtool-1.5.3). We use
libtool-2.2.6b. I build these on the frontend node and use it to
"bootstrap/autogen" the tool we are building. Everything works fine
when we build the frontend version of our tool but when I try to build
a version that runs on the backend nodes of the cray with a different
compiler (/opt/gcc/4.6.1/bin/g++) I'm still getting the
/usr/lib64/libstdc++.la files included in my target build library .la
files.
Any thoughts on what I'm doing wrong? Is there a way to build a
version libtool, for the target, and specify the libraries that should
be used (i.e. the ones that correspond to the compiler)?
Thanks for any help. It will be appreciated.
Jim G.
