Please use the Preformatted Text button (the one with 101010 on it) next time when copying console text into your question. It makes things much easier to read. Thanks.

ok, i'm sorry, first time to make a question.

rchml ( 2016-11-14 11:11:56 -0600 )edit

This is most likely an issue with your CMakeLists.txt. Please update question and add that file. I haven't used nlopt much, but I was able to compile an example I had lying around with CMake by specifically appending path to SO file like the following:

oh, let me end my problem.(get help from labmate) int the cmakelists.txt , focus on the last line. the project_namemeans my findnlopt.cmake works no results. you can change it with ${NLOPT_LIBRARIES} now, it works well. or in the terminal: 5.catkin_make clean and. rm -Rf devel/ build/

which also works. it's just a demo to show the related problems. thanks upfloor guy.

 ## Declare a cpp library
    add_library(${PROJECT_NAME} 
    src/dubins_z_state_space.cpp 
    src/curvature_bvp_solver.cpp 
    src/clothoid_state_space.cpp 
    src/dubins_feasible_path_generator.cpp 
    src/clothoid_z_state_space.cpp
    src/glideslope_bvp_solver.cpp)
    target_link_libraries(${PROJECT_NAME} ${catkin_LIBRARIES} ${NLOPT_LIBRARIES})

    ## Declare a cpp executable
    add_executable(${PROJECT_NAME}_example_dubins_z_path examples/example_dubins_z_path.cpp)
    target_link_libraries(${PROJECT_NAME}_example_dubins_z_path ${PROJECT_NAME} ${catkin_LIBRARIES})

On my system, the nlopt version from apt-get has its headers and libs automatically installed to directories where CMake can find them. Therefore I can get away without using find_package at all and instead directly use target_link_libraries. This isn't very portable, but it will likely solve your issue. In general, you'd likely be better off writing a FindNLOPT.cmake file, but this might also require writing a NLOPTConfig.cmake file (I'm no expert on writing those files, but it seems complicated to get versions that work well on all systems). The following CMakeLists.txt file builds a simple nlopt demo for me.

cmake_minimum_required (VERSION 2.6)

project(nlopt_test)

add_executable(demo example.cpp)
target_link_libraries(demo nlopt)

Perhaps that will help you sort out your errors.

Thanks for converting this to an answer.... I went ahead and edited it to make it more useful as an answer.

i found a findnlopt.cmake file, but do not know how to use it. maybe i should to contact to the project writer.

Thanks! It really works!
