Strengthening a building with OpenVM
I'm hoping to port my app to open vms with HP C ++ 7.3, but just try some examples for a minute to see if this is a potential path, but got a bit stuck. Being brand new to open vms is very fun so far.
Firstly, I don't have a very big building growth in general, after some googling I found a few mentions of people having dcl scripts to create an incentive, but no real scripts. I don't think anyone has or can pint me to someone. I only need asio and threading.
I am currently just trying to compile the asio chat examples. And since I said Im brand new to VMS and the compiler, I was able to get a few things to compile, but now I get "could not open source file sys / select.h", a little search suggests I might need the porting library installed HP or maybe Im just not specifying the prepocessor directive to include the correct code, don't I see anything obvious in socket_types.hpp to install?
Any pointers in the right general direction would be greatly appreciated.

There are no answers, as questio is too open and in an area that I know little about. Just some thoughts.
The choice can be provided by OpenVMS TCPIP (aka UCX) services or another TCP stack. On dcl command line try: $ HELP TCPIP_Services Programming_Interfaces Socket_API
Asynchronous programming in OpenVMS is usually "event driven". Google for SYS $ QIO and AST
There is an open source OpenVMS that contains "NOTES FILES" (tentative index to web forums) Try TELNET for EISNER.DECUS.ORG and you will receive instructions to register. Once you are at the PORTING_TO_VMS conference Once at the NOTES conference you can send the command DIRECTORY or DIR / TIT = xxx Unfortunately there is no topic to select, but you can find interesting reading with NOTES> SEARCH "select (" followed by repeated commands SEARCH) ($ NOTES ... OPEN PORT ... SEARCH "select (" ... SEARCH [] ... SEARCH ...)
The PERL folks have done a wonderful job of making OpenVMS work.
Good luck!
