[ECOS] Running hello.c on i386

[Philip Teng <tcheewan@dso.org.sg>]

I tried to make hello.c using the Makefile given in the /examples.

bash.exe-2.04$ make hello.o
i386-elf-gcc                                     -c -o hello.o -g -Wall
-I//c/us
ers/philip/ecos/stub1_install/include -ffunction-sections
-fdata-sections hello.
c
hello.c:2: stdio.h: No such file or directory
make: *** [hello.o] Error 1

I encountered some errors and I fixed it by adding one more include
path...

bash.exe-2.04$ make hello.o
i386-elf-gcc                                     -c -o hello.o -g -Wall
-I//c/us
ers/philip/ecos/stub1_install/include -I/usr/include -ffunction-sections
-fdata-
sections hello.c
bash.exe-2.04$

The compilation was successful.  The target I used is a PIII machine,
host is Windows NT.  I started up the i386 target using the gdb stub
floppy and run the following:

bash.exe-2.04$ i386-elf-gdb -nw hello.o

Anyone has any idea why the program hit a stop?
