That's my understanding: _append (override style syntax): append without spaces, differs from :=,.=,=.,+=,=+ because assignment is deferred until after parsing, can be used with executable meta data .= : appending without spaces, immediate assignment += : appending with spaces, immediate assignment All of them have left and right hand side variable expansion recursive when used. > > rday > Regards, Robert ..."C++ is an horrible language" - Linux Torvalds My public pgp key is available,at: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x90320BF1 -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
