Re: Problem generating dependency files

[nature]

Thanks for the suggestions Philip!

I got away with the problem by making use of the compiler switch "-MD" to
get the dependency files during compilation itself .
When i included this .d files, make takes lot of time to build (its almost
hung).
Even before this change ,build was slow, but after this change its worst.
I run make in the debug mode to find out where the problem is and was
surprised to see the log message.
Inspite of using VPATH to find for the source files, make searches it
elsewhere and at the end it looks into the path specified in the VPATH .

What is going wrong here? any suggestions please??

Attached is the part of my makefile and the log files.
