Re: [OpenWrt-Devel] [RFC] mklibs.py integration
Hi all, I reworked and fixed the mklibs.py integration and it actually works now. The reported 4KB space saving in the linker binary that florian reported was just simple stripping, not actual relinking. Here are the results with a slightly-bigger-than-standard configuration on a mips target: libuClibc-0.9.30.1.so - before: 401380, after: 253512 libm-0.9.30.1.so - before: 102128, after: 46900 There is no significant space saving on the other libraries yet. - Felix ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

Can you give comparative squashfs sizes instead? Also, this may takes signficantly long periods of time for large numbers of packages. Have you tested with more than the base setup?

I think I did not ask it to strip down all shared libraries, thus it only stripped down the linker. I will try to look at it later in the weekend. -- Best regards, Florian Fainelli Email: flor...@openwrt.org Web: http://openwrt.org IRC: [florian] on irc.freenode.net --- signature.asc Description: This is a digitally signed message part. ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

Wouldn't that mean that fewer programs would result in more removal (due to more unused bits). Or do you strip all libraries and not just uClibc?
