# rabbitmq-c on OpenVMS

This rabbitmq-c has been tested and appears to work on OpenVMS v8.3 on the
Alpha platform, with HP TCP/IP services v5.5
running.  There is no reason to believe it won't work on OpenVMS v8.3 on
IA-64 (Itanium, a.k.a., Integrety) with an equivalent version of TCP/IP.
Or an older version of either of these pieces of software.

NOTE: the maintainers of rabbitmq-c do not have access to an OpenVMS box to
regularly build and test rabbitmq-c, so this code may not build out of the box
and if it does it may not work correctly. However, the build system should
serve as a good starting point for getting something that does work.

# Pre-reqs for building:
- HP C compiler

# Instructions for building
1. Extract this package somewhere where you have space.
2. Run mms or mmk to run the build
3. The result of the build are a library and header files:
  [.librabbitmq]rabbitmq.OLB for the library
  [.librabbitmq]amqp.h and [.librabbitmq]amqp_framing.h for the header files.
To build against the library put these in a place where your compiler/linker can find them

# Other notes about the build:
- The library is built using IEEE float with denormals enabled. This can be
  adjusted by editing the OPTFLAGS line in [.vms]include.mms

  NOTE: the library takes no special care to translate vax-floats into IEEE-floats
   so if you plan on compiling the library with vax-floats enabled you'll need
   to make some changes

- The library is built using /NAMES=(UPPER,TRUNC). Adjust OPTFLAGS line in [.vms]include.mms
  as necessary to get the desired naming scheme.

- The library is built using /POINTER=SHORT. Adjust OPTFLAGS line in [.vms]include.mms as
  necessary to get the desired pointer size
