Ubuntu Compilation

[kogut]

In order to build the fast downward binary in Ubuntu 20.04, I had to append this line to the CMakeLists.txt in fd_copy/src:

target_link_libraries(downward lapack64 bz2 z)

This is for a "release64" build.

This may be related to a broken libcoin package in Ubuntu, and not necessarily an issue with this repository. Just providing the info here in case others run into the same issue.

Thanks @kogut,

I have tried to reproduce your problem in Ubuntu 20.04 but I haven't been able to do so (it compiles fine): I have both tried my usual installation as well as a new installation in a virtual machine. I'm thinking of adding your workaround to a section in the README called "Troubleshooting" or similar. If you have any thoughts on what could be causing this error, let us know and we will add these details in the README.

Thanks again.
