Talk:Binary package guide

My Server and Client(s) Setup
When I get more time, I'll try studying the article. In the meantime, for the past few years, I've used two of my own scripts called "$HOME/bin/sync-server.sh" & "$HOME/bin/sync-clients.sh" with HOSTNAME checking to make sure they're host or client as well as incorporating some of the commands from "Binary Package Guide". I used well structured Bash Scripting techniques with Functions. Again, I'll try posting them sometime (or I can EMail them upon request), but they're pretty basic. The only trivial part is checking for updating the kernel if it's needed, if so then cp the .config file over and build/install the kernel. Then re-run emerge world as some packages break if there's no .config file immediately following a kernel upgrade. The client scripts finally EMail the server to notify emerge completion. The only rsync'ing I do these days, are /etc/portage files and /usr/local/portage containing my custom ebuilds. No NFS utilization as it complicates things greatly. Everything depends on emerge & layman for syncing. Signed: Roger 18:33, 15 November 2011 (UTC)

32 bit and 64 bit Package Binary Server
I've just upgrade to a 64 bit platform (i7 8x3.5Ghz CPU, w/ 32G RAM) and seem quite capable of building both 32 and 64 bit entire system packages within minutes or an hour or so, and distributing to my older 32 bit platforms versus building them specifically for each arch, on each arch. Would be nice to see some Wiki info on making Gentoo build 32 and 64 bit binary packages. From what I'm guessing, the 32 bit builds performed on a 64 bit platform need to be performed within a chrooted build environment?

After figuring or documenting this, making sure the USE flags are compatible across the 32 & 64 bit binaries need to be addressed. ... shrugs ... I'd love to push the older 32 bit platforms into a binary distro, but nothing seems reasonably stable on any distro except Gentoo, including having Gentoo's flexibility with having newer packages/ebuilds easily available.

Is the support for multiple binary package servers still incomplete ?
In my own testing I've not been able to reproduce any of the caveats described. Shouldn't we remove this note ? Sdrik (talk) 15:25, 27 March 2018 (UTC)


 * I'm pretty sure the caveat is still important. You won't run into this unless you're maintaining your own private repositories, and compile two different versions of the same program. --Davidbryant (talk) 14:24, 6 August 2020 (UTC)

What about compiler flags when -march=native is used?
Am I missing something? building a package and control USE flags is one thing. However, given I have on my hots, i.e. builder machine, -march=native in CFLAGS, it will invoke gcc for its own processor, including processor flags at the stage of compilation. And such a code may be useless on another machine. This should be somehow reflected in the document especially given that the handbook suggests -march=native as the most standard approach. --Alex-kas (talk) 19:41, 2 February 2020 (UTC)
