Question

我已经在我的ubuntu 12.04 LTS上安装了boost以及Cassandra cpp driver所需的其他依赖项。当我尝试在下面运行命令时，最终会出现两个错误。我找了解决方案，但找不到任何解决方案。有人说通过添加我尝试的选项-lboost_system链接libboost_system，但没有用。

这是cmd：cmake。＆安培;＆安培;制造＆amp;＆amp; make cql_demo＆amp;＆amp; make cql_test＆amp;＆amp;进行测试＆amp;＆amp; make install -lboost_system

我想做的就是从驱动程序运行演示并与cassandra数据库进行通信！

错误：

Answer 1

以下错误：

/usr/bin/ld: warning: libboost_thread.so.1.55.0, needed by /usr/local/lib/libboost_log.so, may conflict with libboost_thread.so.1.46.1

基本上是说你安装了两个版本的Boost：

自定义版本/usr/local/lib/，可能是版本1.55.0。
系统目录中的另一个，可能是版本1.46.1。

当它们都链接到您的二进制版本时1.46.1获胜。

您需要查看CMake调用的所有完整命令行，以便准确说明问题所在。

未定义引用符号'boost :: future_category（）'
