hi zzh

don't give up, try this simple example :

************* html code : index.html******************

<FORM method="get" ACTION="mult.cgi" >

Please specify the multiplicands:

<INPUT NAME="m" SIZE="5">

<INPUT NAME="n" SIZE="5">

<INPUT TYPE="SUBMIT" VALUE="Multiply!">

</FORM>

****************************************

************** cgi code : mult.c******************

# include <stdio.h># include <stdlib.h>

int main(void)

{

char *data;

long m,n;

printf("%s%c%c\n",

"Content-Type:text/html;charset=iso-8859-1",13,10);

printf("<TITLE>Multiplication results</TITLE>\n");

printf("<H3>Multiplication results</H3>\n");

data = getenv("QUERY_STRING");

if(data == NULL)

printf("

Error! Error in passing data from form to script.");

else if(sscanf(data,"m=%ld&n=%ld",&m,&n)!=2)

printf("

Error! Invalid data. Data must be numeric.");

else

printf("

The product of %ld and %ld is %ld.",m,n,m*n);

return 0;

}

******************************************************

******************** Makefile : Makefile***********************# # configurable options# - set DEBUG = 1 to turn on debugging support#

DEBUG = 1

PROJ_NAME = mult

INSTALL_DIR =

PROGS := $(PROJ_NAME).exe

CFLAGS +=

# # You should not need to modify anything beyond this point#

TOPDIR = .

include ./Rules.mak

ifeq &#39;$(DEBUG)&#39; &#39;1&#39;

PROGS += $(PROGS:.exe=.gdb)

endif

all: $(PROGS)

.PHONY: clean

clean:

-rm -f *.[oad] *.elf *.gdb *.bin *.exe

.PHONY: install

install: all

ifeq "$(INSTALL_DIR)" ""

$(error No installation directory specified)

endif

mkdir -p $(INSTALL_DIR)/bin

install -v $(filter %.exe, $(PROGS)) $(INSTALL_DIR)/bin

***************************************************************

steps to follow :

--> create a new uclinux application

--> add "mult.c" and "Makefile" to project

--> right click on project :

-- creat make target --> yes

-- build make target

--> if compilation success it will create a multi.exe

--> add "index.html" and "mult.exe" to httpd derictory on file system

--> rename "mult.exe" by "mult.cgi"
