c++ - 单眼Total Capture编译过程错误: Makefile:83: recipe for target 'CMakeFiles/mylib.dir/all' failed

我正在尝试使用此仓库:

https://github.com/CMU-Perceptual-Computing-Lab/MonocularTotalCapture

这些是我已经安装的软件包:

ffmpeg
Python 2.7.12 (with TensorFlow 1.5.0, OpenCV, Matplotlib, packages installed with pip3)
openCV 4.2.0
cmake = 3.5.1
OpenCV 2.4.13 (compiled from source with CUDA 9.0, CUDNN 7.0)
Ceres-Solver 1.13.0 (with SuiteSparse)
OpenGL, GLUT, GLEW
libigl https://github.com/libigl/libigl
wget
OpenPose
eigen3, version 3.3.7
Boost version: 1.58.0
GNU 5.4.0

不幸的是，我最后得到一个错误，并且我不知道如何解决。

最佳答案

开始在评论中输入对此的回复，但时间太长...所以我只想回答。

您所拥有的显然是2条警告，但失败却有2条错误。那就是-Werror所做的。现在，您对-Wno-error所做的操作应该可以正常工作，但是如果后面跟随-Werror，则可以将其覆盖。例如，如果我使用gcc构建一个简单的程序，如下所示:

gcc -Wno-error -Werror test.c

-Werror命令已覆盖-Wno-error命令。我只是查看了该项目中的CMakeLists.txt文件，但没有看到-Werror的任何提及。由于默认情况下处于关闭状态，因此它必须在某个位置。这是该项目的CMakeLists.txt文件的摘录:

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wpedantic -Wall -Wextra")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")

我认为可以为-Werror或${OpenMP_C_FLAGS}设置${OpenMP_CXX_Flags}。要对此进行测试，可以使用cmake的message函数。在CMAKE_CXX_FLAGS分配之后添加以下行:

message("CFlags: ${CMAKE_C_FLAGS} CXXFlags: ${CMAKE_CXX_FLAGS}")

我的理论是，您将在某处找到-Werror。如果是这种情况，只需在CMakeLists.txt的这两行(8和10)的末尾添加-Wno-error:

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS} -Wno-error")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS} -Wno-error")

尾随的-Wno-error将覆盖其中的所有-Werror。也许可以使用更纯净的cmake解决方案来解决此问题，但我不是cmake专家。
