I'm replicating a program provided by Richard Heathfield in _C 
Unleashed_.  The custom header for this project is in the same directory 
as the source:

dan@dan-desktop:~/source/unleashed/ch11$ ls -l

-rw-r--r-- 1 dan dan  1612 2000-06-08 16:13 strarr.h

dan@dan-desktop:~/source/unleashed/ch11$

When I compile with -v, this is what I see:

#include "..." search starts here:
#include <...> search starts here:
  /usr/local/include
  /usr/lib/gcc/i486-linux-gnu/4.3.3/include
  /usr/lib/gcc/i486-linux-gnu/4.3.3/include-fixed
  /usr/include
End of search list.

On compilation, I get errors that indicate that gcc is not finding the 
header:
dan@dan-desktop:~/source/unleashed/ch11$  gcc -std=c99 -Wall -Wextra 
t1.c -o out/tmp/ccmpPiuM.o: In function `ReadFile':
t1.c:(.text+0x7e): undefined reference to `AllocStrArray'
t1.c:(.text+0x147): undefined reference to `AddRowsToStrArray'
t1.c:(.text+0x187): undefined reference to `ResizeOneString'
t1.c:(.text+0x203): undefined reference to `AddRowsToStrArray'
t1.c:(.text+0x246): undefined reference to `FreeStrArray'
t1.c:(.text+0x269): undefined reference to `ConsolidateStrArray'
/tmp/ccmpPiuM.o: In function `main':
t1.c:(.text+0x322): undefined reference to `FreeStrArray'
collect2: ld returned 1 exit status
dan@dan-desktop:~/source/unleashed/ch11$

So it doesn't find a header in the same directory.  So, I decide to put 
the header where gcc *is* looking, but ubuntu won't let me put a header 
in any of the directories that are included in the search.

Question 1:  Where am I supposed to put home-rolled headers when I 
compile with gcc on ubuntu?

Thanks for your comment.
