Building C++ programs on IBM i

Build IBM MQ C++ programs on IBM i using the ILE C++ compiler.

IBM ILE C++ for IBM i is a native compiler for C++ programs. The following instructions describe how to use this compiler to create IBM MQ C++ applications using the Hello World! IBM MQ sample program as an example.

1. Install the ILE C++ for IBM i compiler as directed in the Read Me first! manual that accompanies the product.
2. Ensure that the QCXXN library is in your library list.
3. Create the HELLO WORLD sample program:
   1. Create a module:

      CRTCPPMOD MODULE(MYLIB/IMQWRLD) +
      SRCSTMF('/QIBM/ProdData/mqm/samp/imqwrld.cpp') +
      INCDIR('/QIBM/ProdData/mqm/inc') DFTCHAR(*SIGNED) +
      TERASPACE(*YES)
      

      The source for the C++ sample programs can be found in /QIBM/ProdData/mqm/samp and the include files in /QIBM/ProdData/mqm/inc.

      Alternatively, the source can be found in library SRCFILE(QCPPSRC/LIB) SRCMBR(IMQWRLD).

   2. Bind this with IBM MQ-supplied service programs to produce a program object:

      CRTPGM PGM(MYLIB/IMQWRLD) MODULE(MYLIB/IMQWRLD) +
      BNDSRVPGM(QMQM/IMQB23I4 QMQM/IMQS23I4)
      

      To build a threaded application use the re-entrant service programs:

      CRTPGM PGM(MYLIB/IMQWRLD) MODULE(MYLIB/IMQWRLD) +
      BNDSRVPGM(QMQM/IMQB23I4[_R] QMQM/IMQS23I4[_R])
      

   3. Execute the HELLO WORLD sample program, using SYSTEM.DEFAULT.LOCAL.QUEUE:

      CALL PGM(MYLIB/IMQWRLD)
