I fixed this on CVS. I suspect 'ln -s -f' might be unportable so I implemented a
slightly different mechanism with a new make variable RM_LN_S containing the command
used to remove a 'symlink' (/hard copy on mingw32) before creating / recreating it.
I tested the changes on linux by hacking my config.make and replacing 'ln -s' with 'cp
-r'. It works for me.
Please could you try from CVS and report if the new code works on mingw32 as well.
Thanks!

Subject: gnustep-make for windows: linked directory is not really usable
Hi all,
I'm using gnustep-make 1.10.0. to build my application.
I'm also using mingw-3.1.0-1 for gcc3.2 and msys-1.0.10 to run make.
when I run 'make' my project is compiled.
when I later on run 'make debug=yes' the compilation is interrupted with a message
like:
rm: 'obj' is a directory
ln: 'obj': cannot overwrite directory
I run into the same problem when I try to re-make a framework. it complains that
'Current' is a directory...

Filesystem links on Windows are a dead loss. Possibly the Cygwin and MinGW crews will
get round one day to implementing 'ln' in terms of Windows shortcuts, but I hope not:
that'd be yet more incompatible semantics with which to deal.
NeXT^WApple never bothered making the ProjectBuilder pb_makefile system work with soft
links on Windows. A case in point: they'd have used soft links when building a
framework so that Name.framework/Name pointed to Name.framework/Versions/Current/Name
, which in turn pointed to Name.framework/Versions/{ExplicitLatestVersion}/Name .
Which would have been useless on Windows anyway as versioned frameworks wouldn't work,
because the dll loading mechanism is going to find the current Name.dll , whatever
that may be, in .../Library/Tools rather than the appropriate versioned dll from
within .../Library/Frameworks/Name.framework.
Lately I have been trying to build stuff, notably ProjectCenter 0.4.0 on
WindowsXP/MinGW/GNUstep base 1.10.0 and getting all sorts of build-related grief.
Recent revisions to $GNUSTEP_SYSTEM_ROOT/Library/Makefiles/config.make have introduced
a make macro LN_S . By setting that to 'echo no ln -s' on MinGW, and adding similar
macros for rm -f and rm -rf , and setting RM_F to be rm -rf on MinGW, and editing all
project makefiles and all standard makefiles to use these macros: 'make' and 'make
clean' appear to work a lot better. Watch out for rm -[Rr]f when editing.

after investigating I found that it is because obj and Current are 'symlinks' to
actual directories. That is, they are created with $(LN_S).
well, in config.make I found that LN_S = ln -s. This is because 'ln -s' *does* exist
in msys but what it does is a 'cp -r'. This explains the error message in windows.
the workaround i used was to replace any
'rm -f linkdir; $(LN_S) realdir linkdir'
(which fails with message: 'linkdir is a directory')
with
'$(LN_S) -f realdir linkdir'
(ln -s -f forces the remove and the copy of the new dir)
impacted files were:
rules.make
Instance/framework.make
but of course obj and Current remain useless, and i live with it.
