The fun will be restoring read/write on errors so the directories can be erased. 39948 1 mcrapet 2014-01-21 10:40:12 +0000 This is quite tricky. Adding: <code> check_separate_build() { if [ "${S}" != "${B}" ]; then bbnote 'Separate build: chmod a-w ${S}' chmod a-w ${S} fi } do_configure[prefuncs] = "check_separate_build" </cpde> to base.bbclass is easy, but how to revertit ? do_clean will fail because of Permissions. How to detect that do_configure failed? 39949 2 ross.burton 2014-01-21 10:45:01 +0000 To be honest I'm not sure if this is even possible, making the assumption that *nothing* in the build will touch $S is tough. As the creater of this bug let's say I was over-enthusiastic and close it.
