undefined symbol: cache_generate_key_default

Hello,

I have a problem to active one module_cache in apache:


1.First i compile the module mod_cache, not error founds:

$/opt/apache2/bin/apxs -c mod_cache.c
/opt/apache2/build/libtool --silent --mode=compile gcc -prefer-pic
-DAP_HAVE_DESIGNATED_INITIALIZER -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE
-g -O2 -pthread -I/opt/apache2/include -I/opt/apache2/include
-I/opt/apache2/include -c -o mod_cache.lo mod_cache.c && touch
mod_cache.slo
/opt/apache2/build/libtool --silent --mode=link gcc -o mod_cache.la
-rpath /opt/apache2/modules -module -avoid-version mod_cache.lo


2.Copy de .so into directory modules of my instalation:

cp ./modules/experimental/.libs/mod_cache.so /opt/apache2/modules

3.When i start the
/etc/init.d/apache start
Syntax error on line 7 of /opt/apache2/conf_common/httpd.cache.conf:
Cannot load /opt/apache2/modules/mod_cache.so into server:
/opt/apache2/modules/mod_cache.so: undefined symbol:
cache_generate_key_default

Thanks.

For more complicated modules, you need to pass it all the source files
that comprise the module, including e.g. cache_storage.c cache_util.c
-- see modules.mk in the cache/ directory.

(which you don't have if you didn't configure with mod_cache, doh!)

mod_cache.la: mod_cache.slo cache_storage.slo cache_util.slo
$(SH_LINK) -rpath $(libexecdir) -module -avoid-version
mod_cache.lo cache_storage.lo cache_util.lo $(MOD_CACHE_LDADD)

Thanks i execute :

/opt/apache2/bin/apxs -i -c mod_cache.c cache_storage.c cache_util.c
and now load the module.

Sorry to hijack the thread guys but just wondered if the same goes with
mod_mem_cache module I mean the additional .c files in the apxs command?

Thanks,
Igor

Yes, see config.m4 in the modules/cache directory which tells the build
which files are needed.

Thanks Dan. I did that but I got the following error when tried to start
apache afterwards:

httpd: Syntax error on line 70 of /usr/local/apache2/conf/httpd.conf: Cannot
load /usr/local/apache2/modules/mod_mem_cache.so into server: ld.so.1:
../bin/httpd: fatal: relocation error: file
/usr/local/apache2/modules/mod_mem_cache.so: symbol cache_find: referenced
symbol not found


It is apache 2.2.12 running on Solaris 9 in chroot.

Thanks,

Igor

Re: Re: undefined symbol: cache_generate_key_default

Hi, i had a similar problem whit deflate module:

Cannot load /opt/apache2/modules/mod_deflate.so into server:
/opt/apache2/modules
/mod_deflate.so: undefined symbol: inflateEnd

I solve the problem using -lz in the link options, probe to pass this
option to the linker with -Wl apxs command.

/opt/apache2/bin/apxs -i -c -Wl,lz mod_cache.c cache_storage.c cache_util.=
c

Hi marcos,

Thanks for your help I tried that but still getting the same error and I
have no idea why is ld complaining. I set up the LD_LIBRARY_PATH before
execution to :/lib:/usr/lib:/usr/local/lib maybe somethinf is wrong with
that.

Any other suggestions guys?

Thanks,

Igor

Hi marcos,

Thanks for your help I tried that but still getting the s=
ame error and I have no idea why is ld complaining. I set up the LD_LIBRARY=
_PATH before execution to=A0 :/lib:/usr/lib:/usr/local/lib maybe somethinf =
is wrong with that.


Any other suggestions guys?

Ok I fixed it. For anyone interested looking in the config.m4 as Dan
suggested gaives this:

dnl # list of object files for mod_mem_cache
mem_cache_objs="dnl
mod_mem_cache.lo dnl
cache_cache.lo dnl
cache_pqueue.lo dnl
cache_hash.lo dnl

so the command I used to build the module:

# /usr/local/apache2/bin/apxs -c -i mod_mem_cache.c cache_cache.c
cache_pqueue.c cache_hash.c


Thanks to all for your help guys.

Cheers,

Igor

Ok I fixed it. For anyone interested looking in the config.m4 as Dan sugges=
ted gaives this:

dnl #=A0 list of object files for mod_mem_cache
=
mem_cache_objs=3D"dnl
mod_mem_cache.lo dnl
cache_cache.lo dnl >
cache_pqueue.lo dnl

so the command I used to bu=
ild the module:

cache_cache.c cache_pqueue.c cache_hash.c


Thanks to all for your=
help guys.
