Hi, When I run 'cmake -H. -Bbuild', and get much error log like 'CMake Error at modules/mola-common/mola_cmake_functions.cmake:98 (target_compile_features): target_compile_features specified unknown feature "cxx_std_17" for target "dbow2". Call Stack (most recent call first): modules/mola-common/mola_cmake_functions.cmake:112 (mola_set_target_cxx17) modules/mola-common/mola_cmake_functions.cmake:253 (mola_set_target_build_options) externals/DBoW2/CMakeLists.txt:38 (mola_add_library)' And I'm sure I have installed all dependency, can you help me? Thank you.

Hi @Osborn28 ,

What's your OS and OS version? What's your compiler? CMake version?

You can get all these running: 

lsb_release -a
c++ --version
cmake --version

PS: It seems you use a version of CMake older than those we test manually and on CircleCI, so it will be good to know what's your system to see if a fix can be published.

Hi @jlblancoc , Thank you for your help. And I have solved my issue. In order to help others who have the same issue, I will summarize the issues I have encountered.

  1. Install gcc7. url (Thank you again @jlblancoc )
  2. much error log like 'CMake Error at modules/mola-common/mola_cmake_functions.cmake:98 (target_compile_features): target_compile_features specified unknown feature "cxx_std_17" for target "dbow2". The version of CMake is old and should update. Run 'cmake --version' to check it. My version is 3.5.1, and update to 3.9.1 to slove this issue. https://cmake.org/files/v3.9/cmake-3.9.1-Linux-x86_64.tar.gz
  3. '/usr/include/gtsam/base/Vector.h:72:1: error: static assertion failed: Error: GTSAM was built against a different version of Eigen'. GTSAM depends on Eigen3.3., and you can check your Eigen version by to see "/usr/include/eigen3/Eigen/src/Core/util/Macros.h" or "/usr/local/include/eigen3/Eigen/src/Core/util/Macros.h". You can download Eigen 3.3. from http://eigen.tuxfamily.org/index.php?title=Main_Page.

Closing, since the problem was fixed. Hopefully Google will still redirect people here when searching for those exact errors ;-)
