ubuntu - Libigl 示例 102 测试错误

Question

我尝试在 Ubuntu 16.4 上使用 libigl，但在构建示例 102 时遇到了一些错误。

首先，我将 Eigen 安装在/usr/local/include/Eigen/中。

然后，我按照以下命令下载了 libigl 代码:
git clone --recursive https://github.com/libigl/libigl.git
接下来，我尝试构建示例 102。根据这个建议。
The examples can also be built independently using the CMakeLists.txt inside each example folder.
所以下载源代码后，我直接构建示例 102，而不是通过位于/libigl/tutorial/的相应 CMakeLists.txt 构建整个教程。

我喜欢这样:
(1) cd 到文件夹:..../libigl/tutorial/102_DrawMesh

(2) mkdir 构建

(3) 光盘构建

(4) cmake ../

在 cmake ../之后，我收到以下错误，似乎找不到位于 ..../libigl/tutorial/102_DrawMesh 中的 CMakeLists.txt 中指定的所需链接库。

以下是错误:

Can someone give me some advice?

谢谢。

Answer 1

不知道你有没有整理出来。但在 cmake 之后，它们可以独立构建。与其他一切，构建/make程序可以独立完成。

请按照说明执行常规步骤。

cd libigl/tutorial
mkdir build
cd build
cmake ../

您可以修改 CMakeLists.txt在 tutorial只创建您想要的目录，或使用 ccmake ../临时做某事。
