Here is some information on debugging Makefiles:
showing symbol values, and showing file dependencies
There's a good Dr. Dobbs article on this topic, by John Graham-Cumming, at:
or printable, all-in-one page, at http://www.embedded.com/columns/technicalinsights/197003517?printable=true
This article describes some macros you can put in your Makefiles to show you the values of symbols, and to show the dependencies that led to a particular target being built. This is handy if you have a complex Makefile that you are trying to debug.
Makefile Debugger
John has also written a Makefile Debugger.
The following articles describe the debugger and how to use it:
The following resources are needed to use the debugger:
- Download gmsl (a library of gnu make stuff), from http://gmsl.sf.net/
- Download gmd (the debugger itself), from http://gmd.sf.net/
Expand the tarballs from these, and place __gmsl, gmsl and gmd in the directory with the Makefile you wish to debug.
Add the following lines to your Makefile:
include gdm
and
all: $(__BREAKPOINT)
