在Qt中包括共享内存增强库

Question

我安装了BOOST 1.57以允许我使用一些新特性，因此我只需在/usr/local/boost上创建一个目录，其中包含根BOOST文件夹。

我已经成功地创建了示例代码(如这里 )，并使用以下方法编译了它：

 g++ example.cpp -o example -lrt

这是我的.pro文件：

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = Ph2_ACF
TEMPLATE = app

CONFIG += c++11 debug

QMAKE_CXXFLAGS += -g -O1 -w -pedantic -fPIC -std=c++11 -lrt `root-config --cflags --evelibs` -Wcpp

LIBS += -L../lib -lPh2_Interface -lPh2_Description -lPh2_System -lPh2_Tools -lPh2_Utils
LIBS += $(LibraryPaths:%=-L%) -uhal `root-config --glibs`

LIBS += -L/usr/lib/ -lqjson
INCLUDEPATH += /usr/include/qjson/
INCLUDEPATH += $(ROOTSYS)/include

INCLUDEPATH += /../../Ph2DAQ_dev/
INCLUDEPATH += /usr/local/boost
LIBS += -L/usr/local/boost/libs

这是我的错误：

请注意，以前所有的skipping警告都很好，只是这个最后的'shm_open@@GLIBC_2.2.5'似乎破坏了它。

我要补充的是：

#include <boost/interprocess/shared_memory_object.hpp>

// SNIP !

using namespace boost::interprocess;

// SNIP !

shared_memory_object shm_obj
        (
            create_only                  //only create
           ,"shared_memory"              //name
           ,read_write                   //read-write mode
           );

我的一份文件。

知道怎么回事吗？

编辑：

增加：

LIBS += -L/usr/local/boost/libs -lrt

给出了新的错误：

/opt/rh/devtoolset-2/root/usr/libexec/gcc/x86_64-redhat-linux/4.8.2/ld: mainview.o: undefined reference to symbol '_ZN5boost6system15system_categoryEv'

Answer 1

看起来您在编译标志中添加了-lrt，并且在链接阶段没有包含它们。

尝试将-lrt -lboost_system添加到LIBS变量(如-lPh2_Description和其他变量)
