In contrast, when you build in a separate build tree, +# you use a version of srcdir.mk that Configure created, which sets SRCDIR +# to the location of the source tree. + +# This is designed to be included by the top level make file, with +# SRCDIR being passed to all the submakes. That means that when you +# build in a separate build tree, you must build from the top; you +# can't go into a subdirectory and type "make". When you build in the +# _source_ tree, local makes work because every local make file checks +# whether SRCDIR is set, and if it isn't, sets it with the assumption +# that the build directory and source directory are the same. + SRCDIR = $(CURDIR) |
