Hi everyone, the documentation explicitly states that empty elements in CPATH and other variables that control header search path can appear at thebeginning or end of a list. https://gcc.gnu.org/onlinedocs/cpp/Environment-Variables.html But in reality nothing stops you from putting empty element anywhere in the list. export CPATH="$HOME/include::$HOME/project/include" cpp -nostdinc /dev/null -o /dev/null -v 2>&1 | awk '/#include/,/End/' #include "..." search starts here: #include <...> search starts here: /root/include . /root/project/include End of search list. In general I would not consider it to be a bug, but the accent on the beginning and end of the list makes me wonder it it is a bug or a bad description. Thanks, Andrii
