This makefile has been built in 2 halves. 'makfile.generic' which contains things you should change, and 'makefile' which contains thing that can probably be left unchanged.
+
This makefile relies on 4 files:
 +
{|
 +
| <code>makefile</code> || the makefile
 +
|-
 +
| <code>libconfig.mk</code> || configuration for the library - source list, version, output name, system headers, release files, etc...
 +
|-
 +
| <code>buildconfig.mk</code> || configuration for the build environment - output directory and other internal configuration
 +
|-
 +
| <code>config.mk</code> || system / user configuration - install directory, toolchain, compile options, library options
 +
|}
  
−
==makefile.generic==
+
It is also recommended that you have <code>ver.c</code> (see below)
−
<source lang="text">
+
−
### libxbee configuration options:
+
−
 
+
−
### system install directories
+
−
SYS_LIBDIR:=    /usr/lib
+
−
SYS_INCDIR:=    /usr/include
+
−
 
+
−
### setup a cross-compile toolchain (either here, or in the environment)
+
−
#CROSS_COMPILE:=
+
−
 
+
−
### add build 'OPTIONS', these will be passed as -D<name> to gcc etc
+
−
 
+
−
### example from libxbee: un-comment to remove ALL logging (smaller & faster binary)
+
−
#OPTIONS+=      XBEE_DISABLE_LOGGING

This makefile relies on 4 files:

makefile the makefile
libconfig.mk configuration for the library - source list, version, output name, system headers, release files, etc...
buildconfig.mk configuration for the build environment - output directory and other internal configuration
config.mk system / user configuration - install directory, toolchain, compile options, library options

It is also recommended that you have ver.c (see below)
