I'm attempting to install the iPerf3 distribution for AIX 7.3 provided by the AIX Toolbox for Open Source Software web site (https://www.ibm.com/support/pages/aix-toolbox-open-source-software-downloads-alpha#I), however:

=) rpm -Uvh iperf3-3.18-1.aix7.1.ppc.rpm
warning: iperf3-3.18-1.aix7.1.ppc.rpm: Header V4 RSA/SHA256 Signature, key ID 41eea8e0: NOKEY
error: Failed dependencies:
libgcc >= 10.3.0 is needed by iperf3-3.18-1.ppc

I downloaded the libgcc v10.3.0 RPM from the same resource, but:

=) rpm -Uvh libgcc10-10.3.0-6.aix7.3.ppc.rpm
warning: libgcc10-10.3.0-6.aix7.3.ppc.rpm: Header V4 RSA/SHA256 Signature, key ID 41eea8e0: NOKEY
error: Failed dependencies:
libgcc <= 9.1.0 conflicts with libgcc10-10.3.0-6.ppc

Upone further investigation:

=) ls -l /opt/freeware/lib/pthread/libgcc_s.a
lrwxrwxrwx 1 root system 54 Apr 08 2025 /opt/freeware/lib/pthread/libgcc_s.a -> ../gcc/powerpc-ibm-aix7.1.0.0/8.3.0/pthread/libgcc_s.a

=) rpm -qa | egrep "libgcc"
libgcc-8.3.0-2.ppc

However I'm unsure of next steps. Please advise/assist. Thanks!
