Hi all again. Today I finished porting of all basic set of packages that are included by default into leaf.cfg, + some more. I did this mostly for comparision of RAM usage; -O2 + some busybox features + some updated software versions gives ~23M memory usage for i686 iso; 4.1.1 version eats ~20M in that case - IMHO not significant difference. So I think that we can use -O2 for userland.
All built packages seems to be working OK; but some of them gives me a lot of headache due to ugly build scripts that aren't targeted for cross-compilation (or, like perl, have very special meaning of cross-compilation - with checking result on live remote system in case of perl). About moving packages to new toolchain - there is enough simple algorithm: 1) Try to build package w/o hacks, just specifying --host for configure (or, if no configure present, set CC/LD variables) and look into log for compiler/linker names and flags 2) If it uses system compiler - look deeper on configure how it can be forced to use TARGET_CC (usually it's enough to specify CC/LD just for configure) 3) If it tries to pull some info from host system, or has hard-coded compiler - patch makefile/other configure/make-related files to avoid this. 4) In hard cases - look at Google for cross-compilation solutions for that package, or look at first on OpenWRT/DD-WRT toolchain patches. 5) Clean/fix makefile; try to add $(MAKEOPTS) to make call (which actually contains -jN - to build package in multiple 'threads') Also, if you have troubles with some package - try to update it to current version; if you have 'unknown host' error - run 'autoreconf -fvi' before configure; it'll replace old 'config.sub' that doesn't know about uClibc (it's actual for very old packages)ю P.S. It'll be good to make .lwp building/assembling in better way in future, possible - add new package type in buildpacket.pl/buildtool.cfg... It looks too dirty at first look. ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ leaf-devel mailing list leaf-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/leaf-devel
