I'm building the book's code using cygwin and ran across a bug that chewed up a considerable amount of my time. As a newbie, perhaps I'm doing something wrong. On the chance that this is a bug, I hope I can save others from grief.

Chapter 4 is where I discovered the problem. It turns out to be inside the makefile.

The problem is that the Makefile contains the statement 'TMP=tmpnam'. The build fails after the program builds a file $(TMP). Apparently, the local tmpnam.exe file that gets built gets called when make attempts to build the remaining files. (Is there a way to disable the pwd to test this?) I've verified this problem on two out of three machines.

Does anybody know about this bug? Can someone please confirm what I'm experiencing?

Here's a simple test to confirm:

Makefile
--------
TMP=tmpnam

all: $(TMP) program
    gcc -c program.c
--------------------------

create two identical files tmpnam.c and program.c with the following code:
--------------------------
#include <stdio.h>

int main()
{
    printf("Hello World!");
}
--------------------------

Type make. This is what I get:

C:\Temp\Chap04\>make
gcc tmpnam.c -o tmpnam
gcc program.c -o program
make: *** [program] Aborted (core dumped)

C:\Temp\Chap04\>ls
Makefile gcc.exe.stackdump program.c tmpnam.c tmpnam.exe

------------

Any ideas?

HTH someone else.

U should try using knoppix, it's alot more stable and reliable. i tried using cygwin and had an enormous amount of hassles. knoppix allows u to hijack any computer, where i have had problems getting by the restrictions the administrators put on our installing stuff.

try using knoppix, i had nothing but headaches with cygwin. knoppix also allows u to hijack any computer that will boot from a CD-rom. it bypasses those annoying administrators that put restrictions on a user installing stuff.;)

The new DVD version of Knoppix is incredible. Just about every applicaion you could want in a distribution and it is a liveDVD. Give it a try. I purchased my copy from LinuxCentral.
