Not sure what you mean by 'now it will depend on --enable-largefile' since the handling of that flag isn't being changed. I didn't add AC_SYS_LARGEFILE macro; it was already there. The recipe still doesn't need to set that flag... large file support should get enabled if the platform supports it. AC_SYS_LARGEFILE does a compile-time check that off_t is large as expected, and if not it tries some defines (such as _FILE_OFFSET_BITS) to see if they can make off_t check pass. In the 64-bit Linux case, the first check passes, since no tinkering with extra defines is needed, but for 32-bit case _FILE_OFFSET_BITS will get defined. -- _______________________________________________ Openembedded-devel mailing list [email protected] http://lists.openembedded.org/mailman/listinfo/openembedded-devel
