Compliation Error when Qt use Mqueue

[houmingc]

Headers and cpp files that compiles successfully is extracted from codeSourcery and inserted into Qt creator IDE. I am using message queue (MQueue)

Compiler error is as below:
make: *** No rule to make target CMsgQ.cc', needed byCMsgQ.o'. Stop.

CMsgQ.o: undefined reference to symbol 'mq_send@@GLIBC_2.3.4'
error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

Hi,

Can you show your project pro file ?

[houmingc]

QT += core gui
QT += widgets
QT += network
QT +=gui
QT +=gui declarative
QT += xml
---------------------------------------------------------.cc file -----------------
#include <stdio.h>
#include <stdlib.h>
#include <strings.h>
#include <errno.h>

error:
strerror was not declared in this scope
memcpy was not declared in this scope

No SOURCE += CMsgQ.cc ?

[houmingc]

HEADER and SOURCE file is correct, else it will not compile.
I change CMsgQ.cc to CMsgQ.cpp
did a qmake -config serialport.pro

Are you linking to librt ?

[houmingc]

can give an example, how to link and compile
