C++11 在C+中使用libpqxx构建+；11关于Kdevelop 我试图建立一个C++程序，它需要LIPQXX函数。我在Ubuntu上，我正在尝试使用Kdevelop

我用Code:：Blocks成功地实现了这一点，但我正试图找到一个更好的IDE

现在，我对Kdevelop做了些什么。 我创建了一个简单的示例：

#include <pqxx/pqxx>

int main(int argc, char **argv) {
    pqxx::connection c("dbname=xx host=localhost user=xx password=xx");
    return 0;
}

此时，构建过程可以正常工作

但是我需要做些别的事情，我想在C++11中工作。 因此，我添加了一个-std=c++11选项，右键单击我的项目，打开配置>Cmake>高级值>Cmake\U CXX\U标志

我得到以下错误：

您需要libpqxx-4.0.1。下载以下软件包：





下一步：

检查包：md5sum-c libpqxx-4.0.1.tar.gz.md5sum
如果可以：tar-xzvf libpqxx-4.0.1.tar.gz
cd-libpqxx-4.0.1
./configure--prefix=/usr/local--enable shared
您可以选择除“/usr/local”以外的路径。将安装libpqxx

澄清
制造
安装
现在您应该在/usr/local/include中有头文件，在/usr/local/lib中有libpqxx.a、libpqxx.so。如果一切正常，请在IDE中链接库。我不知道，如何在IDE中实现这一点，但这通常是相同的，但属性位于不同的位置。例如，在Eclipse CDT中：

项目/属性/ C+C++ BuID/St/GCC C++编译器/包含/包含路径类型：/Ur/Prime/I/<
在GCC C++链接器/库/库搜索路径类型中：LI>：/Ur/Prime/LIB 
在GCC C++链接器/库/库类型中的LI>：PQXX
项目中：#包括
现在尝试编译。如果可以，试着运行程序。如果你在15号岗位上遇到问题

转到/etc/ld.so.conf.d/，在那里创建一个名为libpqxx-4.0.1.conf的新文件，然后打开文件并在那里键入/usr/local/lib
然后发出ldconfig命令
在我的例子中，使用libpqxx和C++11连接PostgreSQL就是一切。祝你好运
