Our makefile use makedepend to implement auto dependencies but makedepend is getting old and it has trouble parsing some
modern source code ( boost ).
I have tested with using gcc as a replacement and it's working fine so far. However currently it's a two step process
qcc -c -E -Wp,MM .. To generated dependencies files
qcc -c ... to compile
I'd like to use -MMD to do it in one stop, but I can't find the right combination of options to use with qcc. I think
this has been answer before but I can't find any reference to it.

If you're passing -W,-MMD you need to specify the file for cc1/cc1plus
to write out the dependencies to.
e.g qcc -Wp,-MMD,hw.d hw.c

Ah! Didn`t try that because the gcc doc says :
-MD is equivalent to -M -MF file, except that -E is not implied. The driver determines file based on whether an -o
option is given. If it is, the driver uses its argument but with a suffix of .d, otherwise it take the basename of the
input file and applies a .d suffix.

Hi, Ryan,
That's exactly what the IDE's "Check Dependencies On/Off" setting
does. :-)
Cheers,
Christian

Yes I remember Alex asking about the options. :) The feature will be
helpful for people using the new IDE. But not everyone posting in
core-dev-tools uses the IDE and/or QNX recursive mkfiles. ;)

Wot's all this, then?!? Not using the IDE? :-P
One trick that I often use when trying to figure out how to do stuff at
a "low level" is to see what some more abstract tool like the IDE does
to accomplish the same. In a case like this, enable the IDE option on a
test project and see what kind of make magic it perpetrates. :-)

Hi, Mario,
Have you tried using the "Check Dependencies On/Off" context menu action
on your projects? The latest maintenance build on IDE 4.6 (available on
the Foundry27 downloads) supports this additionally on multiple project
selection and an container projects. When you change these settings,
you will be prompted to clean the project. Thereafter, the IDE should
take care of all of the details for you.
HTH,
Christian

It`s not a QNX project but a C Project with our own makefile.

I think the "semi-official" answer is that you can in principle include
qdepend.mk from your $QCONF_OVERRIDES. That being said, I personally
use a one step process of my own (see the attachment from the .PHONY
onward). It currently relies on a couple of as-yet uncommitted changes
to qmacros.mk in order to simplify things, but it can fairly easily be
made to work with a stock qmacros.mk.

Oops: I should have said qdepfile.mk not qdepend.
