I managed to compile a Matlab DLL from the command prompt succesfully
on Windows Vista for profiling. I compiled the __profile.asm file
prior to calling lcclnk.
Now I believe the lcc-generated profiling function
__profile_write_my_engine() did not get triggered when I invoke my DLL
file from Matlab. Everything worked, except that there is no profiler
output.
The entry point for my Matlab DLL is mexFunction(). But if I specify
this in lcclnk using the -entry option, my machine crashes if I
attempt to run invoke the DLL.
Many thanks in advance for your thoughts!
