[yjz...@mail.ustc.edu.cn]

hello,when i'm learning ceres,I have encountered some problems.something like this.there is my source file and CMakeLists.txt below,and i also attached them. thank you!!!

the source file is:

#include <ceres/ceres.h>

int main(int argc, char **argv)

{

  ceres::Problem problem;

 return 0;

}

 

the CMakeLists.txt is:

cmake_minimum_required(VERSION 2.8.0)

set(CMAKE_CXX_FLAGS -std=c++11)

project(ceres_curve_fitting)

find_package(Ceres REQUIRED)

include_directories(${CERES_INCLUDE_DIRS})

add_executable(main main.cpp)

target_link_libraries(main ${CERES_LIBS})

the error is:

CMakeFiles/main.dir/main.cpp.o: In function `main':

main.cpp:(.text+0x18): undefined reference to `ceres::Problem::Problem()'

main.cpp:(.text+0x29): undefined reference to `ceres::Problem::~Problem()'

collect2: error: ld returned 1 exit status

make[2]: *** [main] Error 1

make[1]: *** [CMakeFiles/main.dir/all] Error 2

make: *** [all] Error 2

You need CERES_LIBRARIES not CERES_LIBS in your target_link_libraries() call.
