===== GRASS Makefile writing =====
PGM must be set before including Module.make.
In general, the point at which variables get defined doesn't matter if they are only used in commands, but it matters if they are used in the dependency line. Essentially, dependency lines get expanded at the point they are read, while commands are expanded at the point they are executed.
The list of variables where the order is significant is:
        PGM
        LIB_NAME
        SUBDIRS
        CMD_OBJS
        LIB_OBJS
        LOCAL_HEADERS
        EXTRA_HEADERS
        DEPENDENCIES
The "documentation" for writing Makefiles boils down to: try to find
something similar in the main GRASS tree and use its Makefile as a
reference; if there isn't one, or if that doesn't work, ask on the
developers' list.
Writing documentation for this will result in either wasted effort
(from describing situations which never actually happen) or inadequate
documentation (from failing to describe situations which actually
happen) or (most likely) both.
A couple of points about wx.metadata specifically:
1. Using "parsubdirs" won't work as, because mdlib (presumably) needs
to be built before any of the modules.
2. Files should not be installed using "cp"; use $(INSTALL) for
anything which should be installed with execute permission or
$(INSTALL_DATA) for anything without it.
3. Directories shouldn't be copied with "cp -r". Rather, the
individual destination files should be listed as pre-requisites, so
that "building" the target "builds" the destination files (typically
via pattern rules).


* [[Compile and Install]] hints
wx.metadata/Makefile should probably include "templates" and "config"
in $(SUBDIRS). These would have their own Makefiles; e.g. for
templates/Makefile, something like:


===== CVS =====
        include $(MODULE_TOPDIR)/include/Make/Other.make
* Main [http://grass.ibiblio.org/devel/cvs.php CVS server] help page
 
* Live [http://freegis.org/cgi-bin/viewcvs.cgi/ GRASS WebCVS interface] browsable source code repository
        DSTDIR = $(ETC)/mdlib/templates
* Hints for [[Working with CVS]]
 
        SRCFILES := $(wildcard *.xml)
        DSTFILES := $(patsubst %.xml,$(DSTDIR)/%.xml,$(SRCFILES))
 
        default: $(DSTFILES)
 
        $(DSTDIR)/%.xml: %.xml:
                $(INSTALL_DATA) $< $@


===== QA =====
This should allow wx.metadata/Makefile to be a simple "directory"

GRASS Makefile writing

PGM must be set before including Module.make.

In general, the point at which variables get defined doesn't matter if they are only used in commands, but it matters if they are used in the dependency line. Essentially, dependency lines get expanded at the point they are read, while commands are expanded at the point they are executed.

The list of variables where the order is significant is:

       PGM
       LIB_NAME
       SUBDIRS
       CMD_OBJS
       LIB_OBJS
       LOCAL_HEADERS
       EXTRA_HEADERS
       DEPENDENCIES


The "documentation" for writing Makefiles boils down to: try to find something similar in the main GRASS tree and use its Makefile as a reference; if there isn't one, or if that doesn't work, ask on the developers' list.

Writing documentation for this will result in either wasted effort (from describing situations which never actually happen) or inadequate documentation (from failing to describe situations which actually happen) or (most likely) both.

A couple of points about wx.metadata specifically:

1. Using "parsubdirs" won't work as, because mdlib (presumably) needs to be built before any of the modules.

2. Files should not be installed using "cp"; use $(INSTALL) for anything which should be installed with execute permission or $(INSTALL_DATA) for anything without it.

3. Directories shouldn't be copied with "cp -r". Rather, the individual destination files should be listed as pre-requisites, so that "building" the target "builds" the destination files (typically via pattern rules).

wx.metadata/Makefile should probably include "templates" and "config" in $(SUBDIRS). These would have their own Makefiles; e.g. for templates/Makefile, something like:

       include $(MODULE_TOPDIR)/include/Make/Other.make
 
       DSTDIR = $(ETC)/mdlib/templates
 
       SRCFILES := $(wildcard *.xml)
       DSTFILES := $(patsubst %.xml,$(DSTDIR)/%.xml,$(SRCFILES))
 
       default: $(DSTFILES)
 
       $(DSTDIR)/%.xml: %.xml:
               $(INSTALL_DATA) $< $@

This should allow wx.metadata/Makefile to be a simple "directory" Makefile (i.e. set SUBDIRS, include Dir.make, "default: subdirs").
