Thank you - Jeff.
I did normal (not Makefile) project for Portable server in MVC.

Hello again Liyu,

>From here it appears that you have two options:

1) Use a "makefile" project in visual C++ and build using the EPICS
build
system to create your server. With this approach you don't need to be
intimately familiar with the MS compiler's build options.

2) Otherwise, you can run the EPICS build, observe what options are
being
used, and then configure your visual C++ project to use the same
options.
You will need to translate between the menu options you see in the
visual
C++ GUI and the low level options used by the compiler.

This might occur because the build options you are using are not
compatible
with the libraries created when building EPICS base. In particular, you
will
need to specify options for thread safe library interfaces, the same
debugging options, and the same DLL vs object library choices for the
basic
runtime support as were used to build EPICS base. Alternatively, simply
omitting the gdd library from the link line could be the sole cause of
trouble.
