Hi Jarrett;

This mailing list is for problems with GNU make itself: we cannot debug
build problems for random packages that use GNU make unfortunately:
there are too many and they are too diverse.

This looks like an issue with that particular software package, not with
GNU make (make is basically saying it saw that the linker emitted an
error).

You'll need to find a mailing list dedicated to that particular software
package (QT Creator Embedded) and ask on that list about these problems.
Usually you can find information in a text file in the source kit named
something like README, or INSTALL, or BUGS, or similar.  Otherwise you
can search Google etc.

Good luck!
