building on windows

[kingspride]

Hello, when building on windows with MSVC and under EPICS 7, I end up with a bunch of errors ...

is this a known phenomenon or is reccaster client incompatible with windows somehow?

thanks, W.

Looks like a missing #include <shareLib.h>

[kingspride]

I narrowed it down to an incompatibility between POSIX / Windows. reccaster client uses a lot of ssize_t which is not directly available on Windows (there its SSIZE_T), but can be added via

#if defined(_MSC_VER)
    #include <BaseTsd.h>
    typedef SSIZE_T ssize_t;
#endif

adding it to sockhelpers.h and caster.h brought me here....

[kingspride]

ok it compiles now. I had to add reccaster_SYS_LIBS_WIN32 += ws2_32 to the src Makefile aswell to have it load windows' winsock2 library...

can we create a PR with these changes?

[shroffk]

Please go ahead and make a PR

[kingspride]

its already there: #63

[kingspride]
