  I am working on a windows XP system.  I am doing a command line compile and link using a makefile.  It works except for the fact that it cannot find some header files.

  It has been a long time since I have done this sort of build.  I remember that the path a compiler uses to find a header file is determined by the "Path" that you see when you type "path" on the command line.

  How do you add a new path to the "path"on the command line?  Isn't this what we need to do if the compiler cannot find a header file?

  I think it is

  path= 'PATH'+'C:\somedirectory;'

  or something like that or maybe you have to put a dollar sign in front of the path.  I need to do this just right or else I might wipe out the path string.

  You should be able to specify an include directory with a switch to the compiler. For instance, in GCC you can use the -I switch (dash i). Example: "gcc -I. -IC:/programming/inc test.c".

  If you must use the PATH (and I don't recommend it), use "SET PATH=...;%PATH%". It should only modify the path for that command line session (to permanently modify the PATH, go to system properties, then Advanced and then Environment Variables and change the PATH value).

  To add a directory to the PATH environment variable use the following ...

   set PATH=%PATH%;<directory you want to add>
