Could anyone give me a detailed manual how I can perform cross complication for ARMV5T arch on X86_SuSE? Thanks a lot.

Hi all:


It seems solved. 3 modifications:
1. "mv oe-core/meta/recipes-extended/lighttpd/lighttpd_1.4.31.bb  oe-core/meta/recipes-extended/lighttpd/lighttpd_1.4.30.bb", to make the version is identical with 'oe-core/meta-openembedded/meta-oe/recipes-extended/lighttpd/lighttpd_1.4.30.bbappend'.
2. modify logic of 'check_create_long_filename'  in 'oe-core/meta/classes/sanity.bbclass', since the filesystem is ext4, and the maximum length of filename is 256.
3. Un-modify oe-core/build/conf/bblayers.conf, leave the 'LCONF_VERSION = "5"' as initial value. It may not be the key.


Now it's compiling.


Best regards,
