Probably a better fix is to build a list of directories where we have
come from in the build and pass this to the sub-makes in the depends
targets. Then check to see if we start building in a directory which
exists in the lists.
i.e. something like this:
MY_DIR!=pwd
.if ${_PARENT_DIRS:S/${MY_DIR}//}!=${_PARENT_DIRS:S/ / /g}
.error Recursive build.
.else
_PARENT_DIRS+= ${MY_DIR}
.endif
depends:
make _PARENT_DIRS=${_PARENT_DIRS} ...
Thoughts?
