Environment

OS: Ubuntu 19.10
Kernel: 5.3.0-7625-generic
cmake: 3.13.4
gcc: 9.2.1 20191008 (Ubuntu 9.2.1-9ubuntu2)
All packages updated to latest stable

Steps I followed

Installed ArGOS
by following the commands

git clone https://github.com/ilpincy/argos3.git argos3

sudo apt-get install cmake libfreeimage-dev libfreeimageplus-dev \
  qt5-default freeglut3-dev libxi-dev libxmu-dev liblua5.3-dev \
  lua5.3 doxygen graphviz graphviz-dev asciidoc

 cd argos3
mkdir build_simulator
cd build_simulator
cmake ../src
make
make doc
sudo make install
. setup_env.sh 

Using the same terminal, i.e. keeping env variables from setup_env.sh, tested with argos examples, diffusion_1 and diffusion_10 working properly as expected.

Then starting with installing Buzz,

git clone https://github.com/MISTLab/Buzz.git buzz
cd buzz
mkdir build
cd build
cmake ../src

This place is the problem.

Solution

solution 1

After some trial and testing, following are the steps which solved my issue,

sudo apt install lua5.2 liblua5.2-dev

Getting the file from https://github.com/ilpincy/argos3/blob/b666cadcd0ba103007ced71882bfef5a77e1dc24/src/cmake/FindLua52.cmake
and putting in buzz/src/cmake/FindLua52.cmake solved the issue.

As argos require liblua5.3-dev and buzz has no dependency documented in readme for liblua5.2-dev, I had got stuck. Also tried removing the findLua52 (so lua5.2 and liblua5.2-dev is installed in the system) and trying to update ldconfig. The project can't compile without the file.

As no one else had this issue, maybe I have something wrong/different. Is the cmake line find_package(Lua52 REQUIRED) working without the file ?

solution 2

Diving deeper, got to know, cmake has
https://gitlab.kitware.com/cmake/cmake/blob/master/Modules/FindLua51.cmake to get Lua5.1 but doesn't have "FindLua52.cmake" but instead https://gitlab.kitware.com/cmake/cmake/blob/master/Modules/FindLua.cmake.

So tried changing line at
https://github.com/MISTLab/Buzz/blob/122a0b22c203b78235908afd1453c9a18c0be747/src/cmake/BuzzBuildChecks.cmake#L16

to find_package(Lua REQUIRED)

Which compiled successfully, though it took lua5.3 (installed in the dependency of argos) and not 5.2.

-- Checking for module 'argos3_simulator'
--   Found argos3_simulator, version 3.0.0-beta56
-- Found OpenGL: /usr/lib/x86_64-linux-gnu/libOpenGL.so   
-- Found GLUT: /usr/lib/x86_64-linux-gnu/libglut.so  
-- Found Lua: /usr/lib/x86_64-linux-gnu/liblua5.3.so;/usr/lib/x86_64-linux-gnu/libm.so (found version "5.3.3") 
-- Configuring done

I cannot determine if the lua5.2 is required or lua5.3 as it is compiling with both of the solutions.

Considering Buzz only requires lua when ARGoS is present, and ARGoS is compiled with lua5.3,
changing the line to find_package(Lua REQUIRED) should be the solution I suppose.

Also as shown in https://gitlab.kitware.com/cmake/cmake/blob/master/Modules/FindLua.cmake#L51 any future versions of lua will be auto added, and hence solution 2 will be better.

Please suggest for any future tests required to help in this issue.

This was fixed a while ago in the development repository.
