Error in ExpressionDetector.cpp when building

[tkoenig1]

I'm getting an error trying to compile cvise

tkoenig@gcc188:~/cvise-build> make

Simply removing the offending override with

+++ b/clang_delta/ExpressionDetector.cpp
@@ -75,7 +75,7 @@ public:

where I don't know how to proceed.

If you want to look at my setup, it's on gcc188, in /home/tkoenig , there's nothing secret there.

Please use a newer GCC compiler (I know GCC 11 works fine with LLVM 9), GCC 7 is probably too old.
