C++ 使用Eigen运行CTest时出错

我已尝试从

http://eigen.tuxfamily.org/

安装文件说明了如何使用cmake进行安装

  cd build_dir
  cmake source_dir
  make install

在

makeinstall

之后，我尝试了

maketest

，但所有651个示例都失败了

Errors while running CTest

如何解决这个问题？我在Ubuntu 14.04上

这只是所有示例的一部分，但都失败了。

您应该按照描述构建测试

进行构建测试

这不是很有用。你必须提供更多的信息。你能让这些测试更详细吗？例如什么？我可以添加cmakelist.txt或…？我认为你需要在运行它们之前构建测试。看看

buildtests.sh

脚本，它在makebuildtests之后工作。
