Common issues

Compilation Errors

If you have more than one compiler installed i.e g++ & clang++. The make system might pick up the former. You can explicitly force usage of clang++ by finding the path and passing it in the variable below.

`which clang++`  
cmake .. -DCMAKE_CXX_COMPILER=<path to clang++ from above>

Submodule management

Git maintains a few places where submodule details are cached. Sometimes updates do not come through. ex: Deletion , updating a url of a previously checked out submodule.It is advisable to check these locations for remains or try a new checkout.

• .gitmodules
• .git/config
• .git/modules/*
