I have successfully built asyn-4.10 with SHARED_LIBRARIES=YES and STATIC_BUILD=NO on Windows with Visual Studio 2008 and I also ran into those exact problems when I was compiling asyn previously. My solution was rather simple since I wasn't intending to use SNCSEQ I commented out that test app from the makefile.

This will of course not solve your problem if you need the SNCSEQ module. I have noticed that with using the Visual Studio compiler that there are some preprocessor irregularities in how the epicsShareFunc and epicsShareDef etc.. get translated into the proper __declspec() etc.. It is a bit of a hack, but you can try manually defining what you think should be the correct __declspec() for the pasynManager object in the proper header file. I was experimenting with this previously.

John,

That is probably a problem with the epicsShareFunc stuff.  It looks like you are building with SHARED_LIBRARIES=YES and STATIC_BUILD=NO.  I know that it works OK with SHARED_LIBRARIES=NO and STATIC_BUILD=YES.  I like the latter settings, because then you can take your .exe file to any Windows machine without having to also copy dozens of DLLs.

All,

I am building ASYN 4-10 wth EPICS 3.14.10 on a Windows machine using
Visual Studio 2005, Microsoft C/C++ Optimizing Compiller Version
14.00.50727.762 for 80X86, Perl 5.8.9, GNU Make 3.8.1

The testIPServerApp generates the link error reported below.

Any advice appreciated, thanks.
