[Emc-developers] Building a new C++ kinematics module

[Frank T. <fr...@fr...>]

I'm trying to add a new C++ kinematics module.  If I just put my .cc file in
the src/emc/kinematics directory, nothing happens.

 

I looked in src/Makefile and found these lines (I'm building the simulator
at the moment).

 

$(sort $(RTOBJS)) : objects/rt%.o : %.c

    $(ECHO) Compiling realtime $<

    @mkdir -p $(dir $@)

    $(Q)$(CC) -c $(OPT) $(DEBUG) -DSIM -DSIMULATOR -DRTAPI $(EXTRA_CFLAGS)
$< -o $@

 

 

Firstly, I've never seen a make line with 3 colons, so I'm not really sure
what this does.  If I duplicate the block and change the rule to look for
.cc and run the CXX compiler, like this.

 

 

$(sort $(RTOBJS)) : objects/rt%.o : %.cc

    $(ECHO) Compiling realtime $<

    @mkdir -p $(dir $@)

    $(Q)$(CXX) -c $(OPT) $(DEBUG) -DSIM -DSIMULATOR -DRTAPI $(EXTRA_CFLAGS)
$< -o $@

 

 

I get this repeated for all objects/rt* but still no build.

 

Makefile:880: warning: overriding commands for target
`objects/rtobjects/hal/components/xor2.o'

Makefile:875: warning: ignoring old commands for target
`objects/rtobjects/hal/components/xor2.o

 

It appears the .c and .cc rules are the same.  I using the 2.5.3 source.
Any ideas?
