Hi,
Firstly, i thank Dave K. for helping me.
I don't understand all functionnalities of VPATH, but i think that i don't
used it.
You can find below a minimal test case that demonstrates the problem.
I wish to make it clear that directories name with letter '_' seem maybe to
be the source of problem !
You can find sources files below.
Thanks,
Seb.
Directory tree is :
Test_pb_path

+-- ver_100
|
+---- c : files root.c and foo.c
|
+---- s : file init.S

root.c :
extern int foo(void);
int root(void);
/* root function */
int root(void)
{
int i=0, j;
while(1) {
i++;
j = foo();
}
}
foo.c :
/* foo function */
int foo(void) {
return(55);
}

.globl _start

Then you've typed something wrong. Cygwin make has no problem with that
format. I use it all the time successfully.

Most likely something's wrong in your makefile. Are you using a hardcoded
VPATH that makes it work on your C drive but not any other? Can you strip
down your makefile to a minimal test case that demonstrates the problem
using just a single .c file and %.d:%.c rule?
cheers,
