在Qt中包含共享内存BOOST库

Question

我安装了BOOST 1.57以允许使用一些新功能，因此我只创建了一个包含根BOOST文件夹的目录/usr/local/boost。

我已经成功地创造出here的示例代码和使用编译：

g++ example.cpp -o example -lrt 

这里是我的.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 

，这里是我的错误：

make: *** [Ph2_ACF] Error 1 

只是要注意以前的所有skipping警告之前都很好，它只是这个最后的'shm_open@@GLIBC_2.2.5'这似乎打破了它。

所有我加的是：

#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 
      ); 

进入我的文件之一。

任何想法是怎么回事？

编辑：

添加：

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

给了我新的错误：

/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

它看起来像您添加-lrt的编译标志，而他们没有被列入在链接阶段。

尝试增加-lrt -lboost_system到LIBS变量（如-lPh2_Description，其余）
