Hi, Sorin
Thanks for quick reply.
Here are mod_test.c and Makefile
********************** mod_test.c ****************************************
#include "httpd.h"
#include "http_config.h"
#include "http_protocol.h"
#include "ap_config.h"
#include "my_test.h"
/* The sample content handler */
static int test_handler(request_rec *r)
{
if (strcmp(r->handler, "test")) {
return DECLINED;
}
r->content_type = "text/html";
printf("test_handler is called\n");
if (!r->header_only){
ap_rputs("The sample page from mod_test.c\n", r);
printf("%d\n", add_test(10,20)); // <--- HERE !!!
}
return OK;
}
static void test_register_hooks(apr_pool_t *p)
{
ap_hook_handler(test_handler, NULL, NULL, APR_HOOK_MIDDLE);
}
/* Dispatch list for API hooks */
module AP_MODULE_DECLARE_DATA test_module = {
STANDARD20_MODULE_STUFF,
NULL, /* create per-dir config structures */
NULL, /* merge per-dir config structures */
NULL, /* create per-server config structures */
NULL, /* merge per-server config structures */
NULL, /* table of config file commands */
test_register_hooks /* register hooks */
};
-------------------------------------------------------------------------------------------
********************** Makefile ****************************************
##
## Makefile -- Build procedure for sample test Apache module
## Autogenerated via ``apxs -n test -g''.
##
builddir=.
top_srcdir=/usr/local/apache
top_builddir=/usr/local/apache
include /usr/local/apache/build/special.mk
# the used tools
APXS=apxs
APACHECTL=apachectl
# additional defines, includes and libraries
#DEFS=-Dmy_define=my_value
#INCLUDES=-Imy/include/dir
#LIBS=-Lmy/lib/dir -lmylib
# the default target
all: local-shared-build
# install the shared object file into Apache
install: install-modules-yes
# cleanup
clean:
-rm -f mod_test.o mod_test.lo mod_test.slo mod_test.la
# simple test
test: reload
lynx -mime_header http://localhost/test
# install and activate shared object by reloading Apache to
# force a reload of the shared object file
reload: install restart
# the general Apache start/restart/stop
# procedures
start:
$(APACHECTL) start
restart:
$(APACHECTL) restart
stop:
$(APACHECTL) stop
----------------------------------------------------------------------------------
And I have one more file, modules.mk. it was created when I did
"/usr/local/apache/bin/apxs -g -n test".
I have no idea what it is. ( I didn't modify this file at all )
*************************** modules.mk ***********************
mod_test.la: mod_test.slo
$(SH_LINK) -rpath $(libexecdir) -module -avoid-version mod_test.lo
DISTCLEAN_TARGETS = modules.mk
shared = mod_test.la
-----------------------------------------------------------------------------------
I built the module as follows
$ make
and to install
$ make install
I know I should do something at the "all" target like making
my_test.c's object file and link it to mod_test but don't know how to
specify at all...
Thanks in advance.
