如何在我的项目包中使用c++库gtsam？
提问于 2017-06-06 17:03:02
这是我第一次使用除c++之外的外部OpenCV库。在代码中，我使用了相当多的罗斯功能，但我相信我的问题与ROS无关。我想用GTSAM库构建一个项目。
因此，我将存储库克隆到我的/usr/lib文件夹中，并按照指示进行安装。然后我编写了CMakeLists.txt，在我的.h文件中添加了两个包含，并试图编译。下面显示了我的.h文件的开头、编译错误和CMakeLists.txt。有趣的是，如果我注释掉第二个包含和只包含Pose2.h，编译工作。这意味着编译器至少从库中找到了一些标头，因此正确安装了它。我的cmake代码中应该链接库的部分是从给定这里的示例项目中提取出来的。任何帮助都是非常感谢的。
car_lib.h:
#ifndef CAR_LIB_H
#define CAR_LIB_H
// GTSAM headers
#include <gtsam/geometry/Pose2.h>
#include <gtsam/nonlinear/NonlinearFactorGraph.h>
using namespace gtsam;
// rest of file follows....编译时，我得到以下错误：
...

尝试将## Declare a C++ library下的位替换为
## Declare a C++ library
add_library(car_lib src/car_lib.cpp)
target_link_libraries(car_lib
gtsam
${catkin_LIBRARIES}
)
add_executable(car_node src/car_node)
target_link_libraries(car_node
car_lib
gtsam
${catkin_LIBRARIES}

对于那些试图使用makefile做同样事情的人，下面是解决方案。注意，这是针对没有ROS的简单c++程序的。
all: main.cpp
@g++ main.cpp \
-std=c++11 \
-I /usr/include/eigen3 \
-lboost_system -lboost_filesystem \
-lgtsam \
-o main
