在 Ubuntu 14.04 中安装 aruco lib 时遇到了一些麻烦，我没有任何 sudo 权限，也无法访问 /usr/...

我下载了 .zip aruco lib 并执行了以下操作：

mkdir build
cd build
cmake .. (gives me: -- Build files have been written to: software/aruco-2.0.19/build
make  (gives me some warning msg but nothing critical)
make install (gives an error)

make install 给了我：

-- Install configuration: "Debug"
CMake Error at cmake_install.cmake:36 (FILE):
  file cannot create directory: /usr/local/lib/cmake.  Maybe need
  administrative privileges.

现在简单的问题：

如何在构建文件夹的Makefile文件中设置本地安装lib的路径

好吧，我想将此库与 ros 一起使用，并将其包含在 CMakeLists.txt 中的 cpp 包中，如下所示：

cmake_minimum_required(VERSION 2.8.3)
PROJECT(ros_aruco)

## Find catkin macros and libraries
## if COMPONENTS list like find_package(catkin REQUIRED COMPONENTS xyz)
## is used, also find other catkin packages
FIND_PACKAGE(catkin REQUIRED COMPONENTS roscpp tf std_msgs sensor_msgs geometry_msgs message_generation genmsg cv_bridge image_transport)

#INCLUDE_DIRECTORIES("/hri/localdisk/markus/software/aruco-2.0.19/src")
SET(ARUCO_INCLUDE_DIRS "/hri/localdisk/markus/software/aruco-2.0.19/src") ## headers!
SET(CMAKE_MODULE_PATH "/hri/localdisk/markus/software/aruco-2.0.19/build") ## path to Findaruco.cmake

#SET(CMAKE_MODULE_PATH ${ARUCO_PATH}/lib/cmake)
#SET(ARUCO_INCLUDE_DIRS ${ARUCO_PATH}/include/aruco)

## System dependencies are found with CMake's conventions
FIND_PACKAGE(aruco REQUIRED)
FIND_PACKAGE(OpenCV REQUIRED)

INCLUDE(FindPkgConfig)

SET(ROS_BUILD_TYPE Release)
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11 -march=core-avx-i -O2")

## Specify additional locations of header files
## Your package locations should be listed before other locations
include_directories(
    ${catkin_INCLUDE_DIRS}
    ${ARUCO_INCLUDE_DIRS}
)

add_executable(ros_aruco
    src/ros_aruco.cpp 
)

add_dependencies(ros_aruco ${catkin_EXPORTED_TARGETS})

# give .so librarys:
target_link_libraries(ros_aruco 
    ${catkin_LIBRARIES}
    ${OpenCV_LIBS}
        "/hri/localdisk/markus/software/aruco-2.0.19/build/src"
)

使用该代码进行编译时，我得到了这个我非常想解决的错误：

CMakeFiles/ros_aruco.dir/src/ros_aruco.cpp.o: In function `main':
ros_aruco.cpp:(.text.startup+0x18d): undefined reference to `aruco::CameraParameters::readFromXMLFile(std::string)'

您在编译时遇到的问题是 U 找不到.soaruco 库的共享对象（）

在target_link_libraries你需要添加路径到你的 *.so 由 aruco 构建，我认为你也需要删除FIND_PACKAGE(aruco REQUIRED)

也找到了这个链接。

所以首先，你没有sudo权限，你不能将你的库安装到你的系统默认值/usr/local/lib等等usr/lib。这意味着find_package()不会给你反馈。您可以做的是自己构建所有 aruco 库，add_library()并自己编写link_directories() include_directories() link_library()等。

但是，您也可以修改安装目标。
