Could you help me with??

I`m using pop os 21.04 as OS.

Thanks.

Hey @viniciuscurti, for Pop!_OS, you'll need to build the OR-Tools C++ library from source, then run:

bundle config build.or-tools --with-or-tools-dir=/path/to/or-tools

Hi @ankane !

Thanks for the help, but i still facing a problem.

After done the or-tools instaltion from source, done the bundle config build to the correct path an then run bundle again to install the gem is now getting this error message:

Any suggestion with what i might do to solve?

Thanks again for the usefull tip to install.

And now i`m facing this error after taking a suggetion from another issue to install or-tools on usr/lib than run ldconfig -v.

Try the following:

1. Use the latest version of the gem (0.5.2)
2. Use the latest version of the C++ library (9.0)
3. Paste the output of find /path/to/or-tools/lib and find /path/to/or-tools/include (after compiling the C++ library)
