Hi,

I have an application compiled using gcc under DB2 v8 for Windows
Fixpak 12. It works fine for this fixpak.

However, if I move the application to a different DB2 fixpak (on
Windows), it does not run. (Basically it complains that "Procedure
entry point can not be found", in some place, say sqlasetdata.)  If  I
upgrade db2 on Windows to the same Fixpak, it works.

However, the same application works for DB2 UDB on AIX, HP-UX, Solaris
& Linux, regardless of DB2 versions (as long as it is V6 or later) and
fixpak levels.

The compilation script on Windows (with Cygwin) is as follows:

       ## Compile (but without link: -c) each component:

       gcc -mno-cygwin  -I$DB2PATH/include -c md5.c
       gcc -mno-cygwin  -I$DB2PATH/include -c hash.c
       ......
       gcc -mno-cygwin  -I$DB2PATH/include -c $APPNAME.c

       ## Link all objects to form the application:
       gcc -mno-cygwin -o ${APPNAME}       \
              ${APPNAME}.o                          \
              md5.o                                        \
              hash.o                                       \
              ......                                           \
           $DB2PATH/lib/db2api.lib -L$DB2PATH/lib

Have I missed something during the compilation? How to make the
application work for all fixpaks lower than Fixpak 12 on Windows?

Thanks a lot!
