Hello there,

I'm using a developement board that has its own libraries. I have installed ROS on it and now I need to use publish/subscribe by including its libraries to the CMakeLists.txt of the package. I have to also note that I use Eclipse for compilation, so the CMakeLists.txt is in that form. Here is the Makefile of hardware library that I want to use in CMakeLists.txt:

DIR=$(shell pwd)/../

INCS = -I.\
        -I$(DIR) \
        -I$(DIR)/hardware \
        -I$(DIR)/hardware/environment \
        -I$(DIR)/hardware/environment/cores \
        -I$(DIR)/hardware/environment/cores/environment \
        -I$(DIR)/hardware/environment/variants \
        -I$(DIR)/hardware/environment/variants/sunxi \
        -I$(DIR)/libraries \
        -I$(DIR)/libraries/Serial \
        -I$(DIR)/libraries/SPI \
    -I$(DIR)/libraries/Wire \
    -I$(DIR)/libraries/LiquidCrystal \

OBJS = BasibosAnaProgram

    @mkdir -p $(TARGET)
    for i in $(OBJS); do echo "$(CXX) $(INCS) $$i.cpp -o $(TARGET)/$$i $(LIBS)"; done
    @for i in $(OBJS); do $(CXX) $(INCS) $$i.cpp -o $(TARGET)/$$i $(LIBS); done

    @for i in $(OBJS); do rm -f $(TARGET)/$$i; done

And here is the example CMakeLists.txt that Makefile should be included:

cmake_minimum_required(VERSION 2.4.6)



rosbuild_add_library(${PROJECT_NAME} src/Basibos.cpp)
rosbuild_add_library(${PROJECT_NAME} src/HedefeGitme.cpp)
rosbuild_add_library(${PROJECT_NAME} src/Konum.cpp)
rosbuild_add_library(${PROJECT_NAME} src/Robot.cpp)
rosbuild_add_library(${PROJECT_NAME} src/Sonar.cpp)
rosbuild_add_library(${PROJECT_NAME} src/Zaman.cpp)
rosbuild_add_library(${PROJECT_NAME} src/XMLAyiklayici.cpp)

rosbuild_add_executable(srctest RobotKontrol.cpp)

target_link_libraries(srctest ${PROJECT_NAME})

I'm stuck and can't go forward without help. Any help will be greately appreciated. Thanks in advance

the CMakeLists.txt is not influenced by eclipse

you should be able to build the library (libenvironment.a if I see correctly) with the makefile that you have, and then use find_package(YOUR_LIB) in your CMakeLists.txt (there is no need to build the library every time you build your project)

see cmake help on how to include libraries

I will try that and get back to you. Thanks

How can I use libenvironment.a file in find_package function?

you probably need to write your own find module. don't worry, it's not a big deal. everything is described in the help page i linked to. to sketch the outline: create FindLIBENVIRONMENT.cmake and put it in a dir in ur package inside of the file use FIND_PATH to find the dir with the library's header file add the dir path to CMAKE_MODULE_PATH

that describes finding a library from header files, but I have .a extensioned file. I presume it is like .so

There is too many arguments that will probably not be useful. Can you help me writing this module and attach to your answer. for example the lib is located at ~/libenvironment.a

sorry, u have the figure that one by yourself... I've got work of my own, you see.

okay I've written a FindEnvironment.cmake and moved it to /usr/share/cmake-2.8/Modules/ and now that file cannot be found and it suggests me to make a config.cmake file. (which indicates that Find<>.cmake is not found) What should I do?
