【中文标题】尝试在 Linux Mint 17.1 64 位（未声明/非类型）上“制作”C++ 项目时从 cstdlib 编译错误和类似错误

【英文标题】：Compile Errors from cstdlib and similar when trying to "make" C++-project on Linux Mint 17.1 64bit (not declared/not a type)

【问题描述】：

我有点坚持这一点。 我刚刚安装了一个带有 Linux Mint 的虚拟机，设置了我需要的各种库/包，但在尝试“制作”时遇到错误

由于我的项目需要 OpenCV，因此我按照以下说明进行包安装等： http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html

构建 OpenCV 本身没有任何问题，这就是为什么以下错误代码让我很惊讶......

在项目上使用 cmake 后，我尝试“制作”它并得到以下错误（为了清楚起见，仅选择了几个示例 - 完整的错误日志可在此处找到：http://pastebin.com/Ekn3szTb）：

    /usr/include/x86_64-linux-gnu/bits/mathcalls.h:112:1: error: ‘log10’ was not declared in this scope

     ^

等等……

如果不是所有错误，大多数错误似乎都来自通过“cv.h”（包含在我的头文件中）对标准 c++ 库的调用。

我已经在谷歌上搜索了很长一段时间，几乎尝试了所有与我的问题相关的方法，但没有任何解决方法。

我错过了什么？ 我是 Linux 新手，这就是为什么我不太确定我还需要研究什么.. 我是否缺少某些包裹，还是需要指定其他内容？

/编辑：

这是 cmake 调用：

【问题讨论】：

你可能应该向我们展示你的 cmake

是这么想的，但因为它没有任何意义，所以我没有这样做。秒，编辑它。

显示失败的 gcc 调用，以及所有命令行参数。 （CMAKE_VERBOSE_MAKEFILE 或 --trace）。

@Appuru，因为您在构建时遇到问题，请向我们展示文件，这是您构建的基础——CMakeLists 等。

你也可以编译和运行一个“hello world”c或c++程序吗？

【参考方案1】：

在设置 linux 2 次后，在构建项目的不同阶段仍然出现相同的错误，我找到了它的原因。

jsoncpp 使用名为 features.h 的标头，而标准 c++ 库也包含另一个 features.h。

无论出于何种原因，它对其他所有人都有效，但让我的计算机在构建库时选择了错误的头文件。我之前已经搜索过这个错误，发现它是由 jsoncpp 家伙修复的，但猜测不是所有可能的设置。

我现在使用 jsoncpp 的合并版本，不再与 cmake 链接。

【讨论】：

确实，编译器中没有针对此类错误的检测器。我被困了2天。 （而且不是json，是我自己的项目）。感谢您的帮助。

其实不是文件名有问题，而是include监护人：_FEATURES_H重命名通过。
