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.

Install the ILE C++ for IBM i compiler as directed in the Read Me first! manual that accompanies the product.
Ensure that the QCXXN library is in your library list.
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)
```
