[Linuxppc-users] Toolchain version for RHEL 7.1

[Ulrich Weigand]

That runtime package is supposed to install the AT glibc
(under /opt/atX.X/lib64/...).

The AT dynamic loader (/opt/atX.X/lib64/ld64.so.2) is supposed to
automatically use the AT libraries, including glibc,
from /opt/atX.X/lib64/...

AT-built binaries should have the AT dynamic loader pre-configured so they
always use it.

If this doesn't work for you, one of the above three steps must have failed
somehow.    What is the output when running your binary under "ldd" ?

Many thanks for the heads up.

I’ve installed advance-toolchain-at12.0-runtime on the target machine, but
this does not appear to supply a glibc of the required version.

Is this in another AT RPM package?

Perusing the FAQS

https://developer.ibm.com/linuxonpower/advance-toolchain/adv-tool-usage/#faq1A


Indicates that advance-toolchain-at12.0-runtime is mandatory, but I’m
wondering if a GLIBC_2.23 object is supplied by a different package. I
guess I could go through and install all of them to find out what works,
but it feels like glibc is quite a fundamental building block.

Other FAQs indicate that you can use

/opt/atX.X/sbin/ldconfig

To cache the correct library path, but running this hasn’t resolved the
missing glibc object.

Am I looking at the wrong FAQs?
