Makefile to resursively compile a folder tree

Hi!

I'm looking for a Makefile to compile a tree of source files to a destination tree. I'm only familiar with the basics of make, and a few auto-magic targets, but that's now enough to compile a folder resursively. How can I do that?

(I don't intent to use automake for this project, it concerns my website. it's written in xml, and converted to html with an xslt sheet using sablotron)

Code:

do:
        for i in `find . -type d`; do make e "D=$$i"; done

e:
        cd "$(D)"; echo "making: $(D)##"

...replace the "making:" part with whatever you want to do in those directorys.

But if you want actual dependancies checking in all those directories you'll have to put a Makefile inside each directory.
maybe use "include ../Makefile" so you don't have to rewrite stuff.

niknah,
Thanks for your Makefile help. The 'find' trick was definitely a nice pointer.

I did came up with something completely different in my next version, having read some more online Make books/tutorials.

Code:

# Build list of files
DIRS  = $(shell find . -type d)
FILES = $(subst .xml,.html,$(foreach DIR,$(DIRS),$(wildcard $(DIR)/*.xml)))

# default target, build all dependencies
all: $(FILES)

# other target, remove all files
clean:
    rm -f $(FILES)

# automatic target using pattern matching
%.html: %.xml
    @#echo "Compile $< to $@"
    sabcmd "resources/xslt/codingdomain.xsl" $< $@

# explicitly declare a target phony,
# so it still works if a file called "all" is created
.PHONY: all clean

There is one thing I'm wondering about.. is it possible to support a different "build" directory? (or know what the "source" and "destination" folders are?)

try...

sabcmd "resources/xslt/codingdomain.xsl" $< builddir/$(notdir @)

change builddir to whatever.

Er.. doesn't that give problems with subfolders in the source tree?
Sorry for asking.

builddir should be the full dir, like /xxx/yyy

you set get it with...
TOPDIR=$(shell pwd)
