Failed to proper download the package

[lia2790]

Dear all,

I have tried to download the repo through the following command

git clone --recursive https://github.com/roboptim/roboptim-core.git

as suggested due to the presence of submodules.

But I obtain the following errors

liana@liana-MS-7820:~/catkin_ws/src/iit-relax-ros-pkg (new_version_devel)$ git clone --recursive https://github.com/roboptim/roboptim-core.git

sorry for the Italian but basically it fails in downloading the submodules

• git://github.com/jrl-umi3218/jrl-travis.git
• git://github.com/jrl-umi3218/jrl-cmakemodules.git
• git://github.com/roboptim/roboptim-shared-tests.git

In fact, if I try to install it, I obtain the following errors

liana@liana-MS-7820:~/catkin_ws/src/iit-relax-ros-pkg/roboptim-core/build (master)$ cmake ..
CMake Warning (dev) in CMakeLists.txt:
  No project() command is present.  The top-level CMakeLists.txt file must
  contain a literal, direct call to the project() command.  Add a line of
  code such as

    project(ProjectName)

  near the top of the file, but after cmake_minimum_required().

  CMake is pretending there is a "project(Project)" command on the first
  line.
This warning is for project developers.  Use -Wno-dev to suppress it.

See also "/home/liana/catkin_ws/src/iit-relax-ros-pkg/roboptim-core/build/CMakeFiles/CMakeOutput.log".

I have also to download the package via direct download (.zip file) and run git submodule init && git submodule update, but I obtain the same error during the installation.

How could I solve it?

thank you in advance

Hi @lia2790

GitHub has removed access through the git protocol so you have to use https instead:

git config --global url."https://github".insteadOf git://github

Then you can re-run git submodule update --init to fetch the submodules and the build should work

See #124 for another possible issue down the line.
