RTSDK - I get linking/build errors when I try to make the tutorial 2 example of ETA in RHEL7

Hi,

I downloaded and installed the new RealTime SDK , on our server, I set the ETA path environment variable, the first tutorial code worked perfectly, but the 2nd example generates error during linking/building :

the example i refer is :

developers.lseg.com/en/api-catalog/real-time-opnsrc/rt-sdk-cc/tutorials#eta-consumer-establishing-a-connection-to-a-provider

my setup is as follows :

RHEL 7.9 (Maipo)

gcc : 4.8.5 20150623 (Red Hat 4.8.5-44)

libstdc++.so.6.0.19

any help and/or suggestion would be appreciated

Thanks

Thank you for reaching out to us.

RHEL8_64_GCC831 is for RHEL 8.x and GCC 8.3.1.

If your machine is RHEL 7 and GCC 4.8.5, please use OL7_64_GCC482 instead.

You can change it in the makefile.
