i noticed in r25322 a patch has been committed to support EABI on thumbless ARM v4 CPUs. However, the patch only works if -marmv4 is passed to the linker as the default is armv5t. Unlike openembedded, openwrt does not pass this option to the linker so i modified the patch to #define TARGET_FIX_V4BX_SPEC " --fix-v4bx"
But that makes it unconditional. We should figure out why does it fail right now.
This way, i was able to compile OpenWRT for my SIMPad (See http://git.bocc.de/cgi-bin/gitweb.cgi?p=openwrt.git;a=shortlog;h=refs/heads/simpad).
Care to submit it?
So what would be the correct way to compile for EABI on armv4? OABI is a dead-end, as newer graphics utilities like pango don't work anymore due to the fixed structure alignment. See: Build log: http://tksite.gotdns.org:8010/broken_packages/gemini/pango/compile.txt Developers opinion: http://old.nabble.com/Re%3A-Pango-cross-compile-failure-%28ARM%29-p26706606.html Info on structure alignment on OABI and EABI: http://wiki.debian.org/ArmEabiPort#Structpackingandalignment
As soon as EABI on armv4 works, I nuke OABI support. Imre _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/mailman/listinfo/openwrt-devel
