I am trying to install CARLA on ubuntu 19.04, but it requires clang-7 package. I tried to install clang-7 with
sudo apt install clang-7
But I got the error:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
clang-7 : Depends: libstdc++-5-dev but it is not installable
Depends: libgcc-5-dev but it is not installable
Depends: libobjc-5-dev but it is not installable
Recommends: llvm-7-dev but it is not going to be installed
Recommends: libomp-7-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I tried correcting broken packages by referring to solution_1 and solution_2, but did not solve the issue.
Finally I installed aptitude by referring to this answer, and tried to install clang by:
sudo aptitude install clang-7
But got the the following output:
The following NEW packages will be installed:
clang-7{b} libclang-common-7-dev{a} libclang1-7{a} libomp-7-dev{ab} libomp5-7{ab} llvm-7{a} llvm-7-dev{a} llvm-7-runtime{a}
