Does anyone know why when I try and compile some C code on the bloodshed compiler under windows using the MQ 6.0 headers I get the following message:
2287 C:\Dev-Cpp\include\cmqc.h syntax error before "MQINT64"
2287 C:\Dev-Cpp\include\cmqc.h [Warning] data definition has no type or storage class
I'm a bit of dev novice so if this obvious apologies in advance...
Thanks

Unsupported compiler?
Mixing 32 & 64 bit compilation options?
Mixing 32 & 64 bit header files?
One or more of the above in combination?
Please post platform & option details

Hi,
I think unsupported compiler might be the case - I could compile simple code in 5.3 OK maybe things have changed for 6.0.
Platform is Windows XP - no options specified. Compiler is Bloodshed shareware compiler.
Looks like the compiler is objecting to the following line (amongst others)from cmqc.h :
typedef _int64 MQINT64
I'll try with Visual C++ |

Looks like this is a case of mixing 64 bit and 32 bit libraries...

Nothing to do with libraries. Looks like a compiler that does not have an inbuilt 64-bit datatype. Which is needed for some applications EVEN IF it's a 32-bit program (eg some of the PCF attributes are 64-bit integers). |

Hi,
I'm pretty sure I've posted this here before. Add the following to the top of your code before your MQ includes.
| Code: |
#ifndef _int64
#define _int64 long long
#endif |
Lets see:
- WinXP is a 32-bit OS
- WMQ for Windows is 32-bit
- Compiler on 32-bit OS is generating defines for 32-bit applications
I'm just surprised that IBM made an assumption that '_int64' would be present on a 32-bit OS for a 32-bit compiler. It would have been so easy to put the code above at the top of cmqc.h header file.
Note: Users should not put the code above in the cmqc.h header file as the next time you apply a CSD or RefreshPack, the changes will be lost.

IBM doesn't want to make things too seemless on non-IBM systems. After all, they do sell hardware too, you know!
