# This script gets my preferred and the latest CXX compiler path available
# My compiler priority list: clang++, g++
# I don't use others CXX compilers (icc, icx, ...)

# To simplify things, i assume that whereis sorts entries and tac reverses
# the order, which respects my installations path priority to search.

# Clang candidate installations path, sorted by priority:
# /usr/local/llvm-dev/bin
# /usr/local/llvm/bin
# /usr/local/bin
# /usr/bin
clang_path=$(whereis clang++ | sed 's/\s\+/\n/g' | grep '/bin' | tac | head -n 1)

# GCC candidate installations path, sorted by priority:
# /usr/local/bin
# /usr/bin
gcc_path=$(whereis g++ | sed 's/\s\+/\n/g' | grep '/bin' | tac | head -n 1)
