    changing the gcc standard include search path

    Hi all,

    Is there a way to change where GCC will look for glibc header files ( defult: /usr/include , /usr/local/include ...) ? is there a way to change the spec file and archive this ?
    ( I want to do this without using ENV variables and/or -I switch ).

    Thank you!
    First there was God. He was quite lonely, so he created Dennis.
    Dennis was unimpressed with God.
    So, . . . God created Brian..........Khan Klatt

    Code:
    `-nostdinc'
         Do not search the standard system directories for header files.
         Only the directories you have specified with `-I' options (and the
         directory of the current file, if appropriate) are searched.

    Short of rebuilding your compiler, I don't think you can.

    The switch above allows you to turn off all the standard paths, so you can specify your own. If it worries you that much, write a shell script wrapper around gcc.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
