How to include a singe external source file into a QNX project?   
I have a project that needs to reference a single source file in an external directory containing many source files.  I 
cant use the "extra source path" attribute of the project because that will try to build all the source files under that
 directory.  I used the native Eclipse link mechanism to reference this one file in the project but that caused 
dependency checking problems.  It seems that QNX projects do not like linked files.  Is there another mechanism for 
adding a single external source file to a QNX project?

Hi, Robert,

The QNX Project uses make to build, and because make runs outside of the
Eclipse context, it has no idea about linked resources.

To add a single external file your project, you can edit the common.mk to
add something like this after the "include $(MKFILES_ROOT)/qmacros.mk":

    vpath %.c $(PROJECT_ROOT)/../path/to/external/sources
    SRCS+=extra.c

This will add the folder containing the extra source file to your vpath,
which EXTRA_SRCVPATH does, but doesn't additionally add all of the sources
in that folder.  In this example, the "extra.c" file is assumed to be in the
../path/to/external/sources folder relative to the current project root
folder.

HTH,

Christian

This helps somewhat but I dislike having to hardcode filenames into common.mk.  Why can't the QNX plugin to Eclipse look
 for linked resources and modify its make files accordingly?

Hi, Robert,

I think your suggestion is a good idea.  I've entered it into our database
for consideration in a future release.  I expect we'll have to think
carefully about how to encode paths in the makefile as relative to the
project root, etc.  There will be several use cases to account for.

Thanks!

Christian
