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/arm-linux/bin/arm-linux-gcc –o hello-release hello.c
/usr/local/arm-linux/bin/arm-linux-strip –s hello-release
/usr/local/arm-linux/bin/arm-linux-gcc –ggdb -o hello-debug hello.c
[root@localhost hello]# _
Next, execute make to generate hello-release and hello-debug, which are described below:
hello-release—an ARM platform execution file (created specifically to run on the UC-7112-LX
Plus)
hello-debug—an ARM platform GDB debug server execution file (see Chapter 5 for details about
the GDB debug tool).
NOTE Since Moxa’s tool chain places a specially designed Makefile in the directory
/tmp/example
/UC-7112-LX_Plus /hello, be sure to type the #make command from within that
directory. This special Makefile uses the arm-linux-gcc compiler to compile the hello.c source
code for the Moxa ART environment. If you type the #make command from within any other
directory, Linux will use the x86 compiler (for example, cc or gcc).
Uploading and Running the “Hello” Program
Use the following commands to upload hello-release to the UC-7112-LX Plus by 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 then use the put command
to initiate the file transfer:
ftp> bin
ftp> put hello-release
3. From the UC-7112-LX Plus, type:
# chmod +x hello-release
# ./hello-release
The word Hello will be printed on the screen.
root@Moxa:~# ./hello-release
Hello
