Reporting in I've been a little busy and my pi has been working hard compiling successfully
I tried it out and the base install (without setting anything up) works like I expected. Now I'm rebuilding with wireless network tools and more customization to my build.
I had one issue with my keyboard not being recognized and having to use a different one.
The compile is still going on I keep having small issues with the compile missing something and having to restart it after sorting it out however...
The bottom line is yes you can compile Buildroot on a RPI but it will take days! Just getting menuconfigs to build took 45-60 minutes for busybox and I went to bed waiting for the kernel one so 3 hours plus for that one. Buildroot's menuconfig is not such a wait.
My RPI 3B+ has gcc 9 installed and a 1 GB swap file otherwise nothing really special beyond that.
I'll report back again after my customized version is built.
My last build has finished successfully. I had two problems with it one was running out of space on my drive easy to solve. The other was a missing build library libstdc++6 this was installed didn't have support for LIBCXX_3.4.26
I had to install the package libstdc++6_9.1.0-5_armhf.deb
from the Debian Experimental branch. I just used the following command to install and it worked.
Code: Select all
sudo dpkg --ignore-depends=gcc-9-base -i libstdc++6_9.1.0-5_armhf.deb
I really want to try this on a PI 4B with 4Gb of ram, swapping is killing the performance.
