Compiling Hello.c
The package CD contains several example programs. Here we use
Hello.c
as an example to show
you how to compile and run your applications. Type the following commands from your PC to
copy the files used for this example from the CD to your computer’s hard drive:
# cd /tmp/
# mkdir example
# cp –r /mnt/cdrom/example/* /tmp/example
To compile the program, go to the
Hello
subdirectory and issue the following commands:
#cd example/hello #make
You should receive the following response:
[root@localhost hello]# make
/usr/local/mxscaleb/bin/mxscaleb-gcc –o hello-release hello.c
/usr/local/mxscaleb/bin/mxscaleb-strip –s hello-release
/usr/local/mxscaleb/bin/mxscaleb-gcc –ggdb -o hello-debug hello.c
[root@localhost hello]# _
Next, execute the
hello.exe
file to generate
hello-release
and
hello-debug
, which are described
below:
hello-release
—an IXP platform execution file (created specifically to run on the DA-660)
hello-debug
—an IXP platform GDB debug server execution file (see Chapter 5 for details about
the GDB debug tool).
NOTE
Be sure to type the
#make
command from within the
/tmp/example/hello
directory, since UC’s
tool chain places a specially designed
Makefile
in that directory. This special Makefile uses the
mxscale-gcc compiler to compile the hello.c source code for the Xscale environment. If you type
the
#make
command from any other directory, Linux will use the x86 compiler (for example, cc or
gcc).
Refer to Chapter 5 to see a Makefile example.
Uploading and Running the “Hello” Program
Use the following commands to upload
hello-release
to the DA-660 via FTP.
1.
From the PC, type:
#ftp 192.168.3.127
2.
Use the
bin
command to set the transfer mode to Binary mode, and the
put
command to
initiate the file transfer:
ftp> bin
ftp> put hello-release
3.
From the DA-660, type:
# chmod +x hello-release
# ./hello-release
The word
Hello
will be printed on the screen.
root@Moxa:~# ./hello-release
Hello
