Hello automakers! I'm using autoconf 2.69 and automake 1.11.6 (Debian 7 stable). Recently I tried defining the source code folder name using a variable and strange things happen. I'm not sure whether this is a bug or my mistake. Here's the revelant part from Makefile.am, before the change, which *does* work:
lib_LTLIBRARIES = libsgp.la
libsgp_la_SOURCES = \
src/Command.cpp \
src/CommandStack.cpp
Now, the change I made is here below. The result is that .Plo files are created
under $(src)/.deps instead of src/.deps, and then the code that uses them fails
to find them and `make` failes.
src = src
lib_LTLIBRARIES = libsgp.la
libsgp_la_SOURCES = \
$(src)/Command.cpp \
$(src)/CommandStack.cpp
The following change surprisingly causes `make` to succeed, but the .Plo files
are still created in the wrong place. I don't mind having a folder named $(src)
literally, but it's not the intended behavior.
code = src
src = $(code)
lib_LTLIBRARIES = libsgp.la
libsgp_la_SOURCES = \
$(src)/Command.cpp \
$(src)/CommandStack.cpp
I also tried using
src := src
but the result was the same.
Why does it happen? Is this a known problem? I didn't find any material on
the web. Of course I can move the definition of "src" to configure.ac, but I'd
like to know what I'm missing (or is it a bug).
If you use OpenNIC, the code can be browsed (and cloned of course) at
http://git.partager.null/sgp-dox.git.
