Getting Error while installing titan.core

Question

While installing the Titan (Repository taken form the site https://gitlab.eclipse.org/eclipse/titan/titan.core), getting the error as below

Solved the Makefile issue in my previous question(make: *** No rule to make target '-', needed by 'TTCN3_DIR'. Stop), Thanks @user:939557

Error Details:
