Lepsie ako upravovat hlavickove subory by bolo upravit prezeranie ciest
includov. prepinace -I a -I-

skontrolujte pomocou gcc -print-search-dirs

$ gcc -print-search-dirs
install: /usr/lib/gcc-lib/i386-linux/2.95.4/
programs:
/usr/lib/gcc-lib/i386-linux/2.95.4/:/usr/lib/gcc-lib/i386-linux/:/usr/lib/gcc/i386-linux/2.95.4/:/usr/lib/gcc/i386-linux/:/usr/i386-linux/bin/i386-linux/2.95.4/:/usr/i386-linux/bin/
libraries:
/usr/lib/gcc-lib/i386-linux/2.95.4/:/usr/lib/gcc/i386-linux/2.95.4/:/usr/i386-linux/lib/i386-linux/2.95.4/:/usr/i386-linux/lib/:/usr/lib/i386-linux/2.95.4/:/usr/lib/:/lib/i386-linux/2.95.4/:/lib/:/usr/lib/i386-linux/2.95.4/:/usr/lib/

Pripadne sa to da este upravit pomocou -B

gcc --help
man gcc

              ^^^^^
Podstatna je tato chyba. Nenasiel definiciu DIR, tak prepoklada, ze je
to premenna a tvrdi, ze nie je definovana. Ostatne chyby su len
nabalovane. Treba zistit, kde ma byt definovane DIR a preco ho nenasiel.
Prepokladam, ze to bude zlym poradim ciest v gcc.
