Patched GNU Make 4.1 sources to add improved error reporting, tracing, target listing, and a debugger. See the remake-3-82 branch for a patched GNU Make 3.82.
Although there's a full debugger here, most of the time I can get by using no options since normal output is a little more verbose and detailed. When that isn't enough, I use the --trace or -x option, e.g:
remake -x <other make options>
But if you want the full debugger, use --debugger or -X:
remake -X <other make options>
To enter the debugger from inside a Makefile, use the built-in function $(debugger). For example here is a Makefile:
all: $(debugger 'arg not used') echo Nothing here, move along
When GNU Make is inside the all target, it will make a call to the debugger. The string after debugger is not used, but seems to be needed to get parsing right.
If there is project that you want a list of "interesting" Makefile targets, try:
If the project has commented its Makefile using remake-friendly comments you may get output like this:
ChangeLog # create ChangeLog fom git log via git2cl build # Do what it takes to build software locally check # Run all tests clean # Remove OS- and platform-specific derived files. dist # Create source and binary distribution distclean # Remove all derived files. Like "clean" on steroids. install # Install package test # Same as check
To get a list of all targets, interesting or not, use --targets instead of --tasks.
$ autoreconf -i $ ./configure $ make update $ make && make check && sudo make install
