how to compile WebSphere MQ ".c" code ?

[Sebastia Altemir]

I am trying to use IBM WebSphere MQ "c" code (sample follows).

The header file "cmqc.h" is located in c:\mq\tools\c\include",
and the "librariy" file correponding to "cmqc.h" header is "mqm.lib" (server) or "mqic32.lib" (client),
located at "c:\mq\tools\lib" and also "c:\mq\tools\lib64"

Can someone provide me the syntax for compiling from command line ?

The CMD file I have until now is

===
c:\"Program Files (x86)"\Dev-Cpp\MinGW64\bin\gcc prova.c
-I"c:\mq\tools\c\include"
-L"c:\mq\tools\Lib\mqm.lib"
-o prova.exe

Thanks. Sebastian.

pd.- my code :

===
// fix for MinGW

ifndef _int64

define _int64 long long

endif

include < stdio.h >

include < stdlib.h >

include < string.h >

include < cmqc.h >

MQCHAR QMName [49] = "" ; / default QMgr name /

int main ( int argc, char ** argv )
{
printf ( ">>> MQCONN(). QMN [%s].\n", QMgrName ) ;

MQCONN ( QMgrName, / queue manager /
& Hcon, / connection handle /
& CompCode, / completion code /
& CReason ) ; / reason code /

}

Error : MQM.LIB is not found (or not correct format ...)

The complete error is this one :

I have read that MQM.LIB is not completely "standard" ...

It compiles OK with Microsoft "CL" compiler,
... but using Borland BCC32 I have this error :

Error: 'C:\MQ\Tools\Lib\MQM.LIB' contains invalid OMF record, type 0x21 (possibly COFF)

Any clue ?

[Sebastia Altemir]

I'd say I fixed it, by using this compilation command :

===
c:\"Program Files (x86)"\Dev-Cpp\MinGW64\bin\gcc amqsecha.c -I"c:\mq\tools\c\include" -L"c:\mq\tools\Lib64" -o AMQSECHA.EXE -lmqm
===

Sebastian, running few tests.

[Sebastia Altemir]

Compilation ends OK, but MQCONN() fails with no explanation.
So, "gcc" is not compatible with "mqm.lib" ?
What is that COFF stuff ?
Sebastian.
