There should not be a comma immediately after subst. wrong: $(subst,\\,\\\\,$(shell cygpath -w $<)) right: $(subst \\,\\\\,$(shell cygpath -w $<)) Scott Carter -----Original Message----- From: Chad Loder [mailto:cloder AT acm DOT org] Sent: Tuesday, October 03, 2000 06:55 PM To: cygwin AT sourceware DOT cygnus DOT com Subject: Cygpath, backslashes, and sh.exe Hi all. Thanks for your help with cygpath (I *did* look in the FAQ, I just didn't know what to look for). :) cygpath *seems* to be doing the right thing (it's hard to tell), but there is some sort of problem with backslashes. I have a rule like this: %.obj : %.cpp $(CC) $(CPPFLAGS) $(shell cygpath -w $<) The idea is that this will invoke sh.exe with something like: /c/VC98/bin/cl.exe /Fo:globref.obj c:\r7\jni\src\globref.cpp But instead it seems to do: /c/VC98/bin/cl.exe /Fo:globref.obj c:r7jnisrcglobref.cpp which causes the compiler to bomb out with: fatal error C1083: Cannot open source file: 'c:r7jnisrcglobref.cpp': No such file or directory I figured I need to escape the backslashes before passing them to a shell command. So I tried things like: %.obj : %.cpp $(CC) $(CPPFLAGS) $(subst,\\,\\\\,$(shell cygpath -w $<)) but the subst function seems to just return an empty string (this happens even when I use something without backslashes, like $(subst,a,b,whatever). Has anyone run into this? Thanks, c c At 05:50 PM 10/3/2000 -0500, you wrote: >Chad: > > Hey, no problem. Let me know if you run into other problems.
