GNU Make 3.81
...
$ make -f -
$(info $(realpath d:/temp))
^Z
c:/progs/cygwin/home/nosek/d:/temp
I've tried it with:
* Cygwin's make,
* GnuWin32 binary release make,
* make.exe built with MSVC++ from 3.81 sources.
I don't know if it's a win32 specific problem, or a general make 3.81
"feature" (or just lack of feature).
It's the is-a-colon-a-path-separator-or-is-it-a-drive-letter-identifier
problem discussed in the thread "VPATH of the form C:/foo" on this list over
the last few days, check the archives.
No, this is a different problem: $realpath and $abspath are broken on
Windows in Make 3.81, except in the Cygwin port with Posix file names
(that start with a slash). (It cannot be the same problem, since
$abspath takes a single file name, not a list of directories, so the
significance of a colon as path separator is not an issue here.)
The next version will hopefully have this fixed. If you must have
$abspath now, try the patch here:
http://lists.gnu.org/archive/html/make-w32/2006-05/msg00042.html
If anybody cares for a pure-make patch-wrapper against that, the following:
myrealpath = $(join \
$(filter %:,$(subst :,: ,$1)),\
$(realpath $(filter-out %:,$(subst :,: ,$1))))
seems to work for me, even if the style ain't that cool at all...
