In gcc 4.5.2 this option is ignored - gcc does not print any message when non-existing include dir is specified. gcc 4.7.3 prints warning only. gcc (both tested versions) changes this warnings into errors when both -Wmissing-include-dirs -Werror options are used, but this is not an option for be because of other warnings which are in my code. I tested this using following command: g++ -c test.cc -o test.o -I/a -Werror=missing-include-dirs ^ permalink raw reply [flat|nested] 4+ messages in thread
