Re: Compiling base on Rocky Linux 9

[Andrew Johnson via Tech-talk <tech-talk@aps.anl.gov>]

Hi Ernesto,

Have you tried building R3.15.9 or EPICS 7.0.7 at all on Rocky 9? What GCC version does that come with?

I'm not sure whether we have made changes since then to fix that, but 3.15.6 is now 4 years old. You might be able to add something like

ARCH_DEP_CXXFLAGS = -std=c++11

to your configure/os/CONFIG_SITE.linux-x86_64.linux-x86_64 file to tell GCC to back down to an earlier C++ standard.

Hello guys,
I'm having trouble in compiling EPICS base 3.15.6 in rocky linux 9.
I believe it should be something related to the enforcement rules on gcc compiler.
Someone knows how tho workaround this?
Thank you!!
