Hi,
I sure did try that. I also tried to install devtools (no luck there).
[root@localhost source]# yum list installed binutils* gcc-c++* libc-devel* Installed Packages binutils.armv7hl 2.27-44.base.el7_9.1 @updates gcc-c++.armv7hl 4.8.5-44.el7 @base
And:
[root@localhost source]# gcc -v --help 2>/dev/null| grep '-std=c++' -ansi A synonym for -std=c89 (for C) or -std=c++98 (for -std=c++03 Conform to the ISO 1998 C++ standard revised by -std=c++0x Deprecated in favor of -std=c++11 -std=c++11 Conform to the ISO 2011 C++ standard -std=c++1y Conform to the ISO 201y(7?) C++ draft standard -std=c++98 Conform to the ISO 1998 C++ standard revised by
So looks like gcc-c++ 4.8.5-44 only gets me to C++11. Almost there. For some reason I decided to use std::filesystem a bunch of places and it looks like it is only supported in C++17.

Not sure what version of gcc-c++ that will get you. My CentOS 7 VPS has gcc-c++-4.8.5-44.el7.x86_64 on it, so I would assume the above should get you gcc-c++-4.8.5-44.el7.armv7hl. OTOH, my Raspberry Pi 4 build box with Raspberry Pi OS (based on Debian 10) has gcc version 8.3.0 (Raspbian 8.3.0-6+rpi1). Maybe you should just get an up-to-date Raspberry Pi OS image. Then after 'sudo apt update;sudo apt full-upgrade -y' you can do 'sudo apt install g++ binutils libc-dev'.

Hi,
I have a program I want to run on a Raspberry PI 4 that was written on an x86_64 architecture. So I downloaded the Raspberry PI image of CentOS 7 and now I'm on armv7hl. Unfortunately, there doesn't appear to be any devtools for arm at all. Is there an easy(ish) way to get c++ 17 this architecture?
Thank you!
Will
