ld: undefined reference to `lua_`. I don’t know why ld cannot reference lua even though its there

  arch, c++, ld, lua, manjaro

I’m trying to install the code from this git-repo for a university project and I’m stuck because ld does not seem to be able to link lua properly. I followed the install instructions and compile the code with:

catkin_make -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 -DCMAKE_CXX_STANDARD=14 

which fails with several messages like:

/usr/bin/ld: /home/felixk/catkin_ws/devel/lib/libflatland_lib.so: undefined reference to `lua_toboolean(lua_State*, int)'
/usr/bin/ld: /home/felixk/catkin_ws/devel/lib/libflatland_lib.so: undefined reference to `lua_tonumberx(lua_State*, int, int*)'
...
/usr/bin/ld: /home/felixk/catkin_ws/devel/lib/libflatland_lib.so: undefined reference to `lua_pushstring(lua_State*, char const*)'
/usr/bin/ld: /home/felixk/catkin_ws/devel/lib/libflatland_lib.so: undefined reference to `lua_isstring(lua_State*, int)'
collect2: error: ld returned 1 exit status

The code was tested and works on Ubuntu 18.04 but I’m trying to get it to work on Manjaro. The manual states that liblua5.2-dev is needed and I installed lua52 from the AUR which seems to provide the right libraries.

The output of ldd is:

ldd /home/felixk/catkin_ws/devel/lib/libflatland_lib.so | grep lua
        liblua5.2.so.5.2 => /usr/lib/liblua5.2.so.5.2 (0x00007f23fd51c000)

Then I checked if /usr/lib/liblua5.2.so.5.2 exists and it does. I tried to use readelf to check whether liblua5.2.so.5.2 contains the undefined references:

readelf -s /usr/lib/liblua5.2.so.5.2

It seems like all the undefined references exist in /usr/lib/liblua5.2.so.5.2 and I don’t know how to go on from here.

Other answers on SO suggest to put the #includes of lua into a extern "C" like so:

extern "C"{
    #include <lua5.2/lualib.h>
    #include <lua5.2/lauxlib.h>
    #include <lua5.2/lua.h>
}

But I would rather not change the given code and wouldn’t even know how to find out in which files lua is #included .

Optimally I would only like to change the make command catkin_make -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 -DCMAKE_CXX_STANDARD=14 to help ld to properly link but I don’t know if thats possible. I’m not really familiar with make, cmake or in this case catkin_make and couldn’t find out if it is possible to add linker options in the make command.
