Hi,

    I am working on gcc version 3.4.4. I successfully compiled all the
source files and able to build .exe and .dll. I am able to debug the
code properly using gdb/ddd. But while I tried to simulate the code, I
am facing problems. It is not able to simulate. .dll is not even
loading  into simulator. What might be the problem.

Here is the makefile.mk I am using,

########Makefile.mk
