Building Images. Missing Architectures
by Michael Nehring 18 Aug '22

18 Aug '22

Dear frrouting devs, your frrounting/frr images gets buildet for multiple architectures, which is very good thank you <3 But is there a reason why the latest tag is only builded in amd64? It would be nice if the latest tag has also the different architectures. Best Regards Michael Nehring

Is anyone aware if this issue is fixed after 8.1 ? Can someone share details on how to enable gdb option to get full bt, I tried --enable-dev-build but I am getting same bt without local info.

Error when running frr from source code
by hieunt562＠viettel.com.vn 30 Jun '22

30 Jun '22

Hi all. I want to install FRR 8.2.2 release from source code for ospfd running on CenOS 7. So, I followed the guide line from http://docs.frrouting.org/projects/dev-guide/en/latest/building-frr-for-cent os7.html. - First, when I run: ./configure --bindir=/usr/bin --sbindir=/usr/lib/frr --sysconfdir=/etc/frr --libdir=/usr/lib/frr --libexecdir=/usr/lib/frr --localstatedir=/var/run/frr --with-moduledir=/usr/lib/frr/modules --enable-snmp=agentx --enable-multipath=64 --enable-user=frr --enable-group=frr --enable-vty-group=frrvty --disable-ldpd --enable-fpm --with-pkg-git-version --with-pkg-extra-version=-MyOwnFRRVersion SPHINXBUILD=/usr/bin/sphinx-build I got two warnings: configure: WARNING: sphinx is missing but required to build documentation configure: WARNING: pytest is missing, unit tests cannot be performed - After compile source and install I run sudo systemctl start frr I got error message like below: [root@localhost frr]# sudo systemctl start frr Job for frr.service failed. See "systemctl status frr.service" and "journalctl -xe" for details.
