[mod_backhand-users] mod_backhand and Raven

Hello,

I am currently trying to add mod_backhand in to my standard install of
Raven - 1.5.2, as a dso, and am getting errors on startup.

Here is what I have done so far (I have included output in case someone
notices something in the make or .configure process)...
- untar mod_backhnad, .configure, make, copy files (*.h and
libbackhand.so) to locations...., edit httpsd.conf

I get the following error on
LoadModule backhand_module libexec/libbackhand.so .....

bash-2.03$ apache-configtest
Syntax error on line 62 of /usr/local/apache/conf/httpsd.conf:
Cannot load /usr/local/apache/libexec/libbackhand.so into server:
ld.so.1: /usr/local/apache/bin/httpsd: fatal: relocation error: file
/usr/local/apache/libexec/libbackhand.so: symbol kstat_read: referenced
symbol not found

Could somone give lend a helping hand on this one?

OK, just a warning: loadable candidacy functions do not work correctly on
Solaris when mod_backhand itself is a dso. If you don't need them, it
shouldn't matter.

Hmm... the configure script isn't robust enough to handle Solaris. You need
top establish link requirement when you build the libbackhand.so dso;
specifically: -lkstat -ldl -lm

So on the compile line (whatever the VERY LAST thing that apxs does to make
libbackhand.so) you need to append -lkstat -ldl -lm and reissue that command.
Then Solaris should automagically load kstat, dl and m upon loading
libbackhand.so.

The command line you are interested in will start something like:

gcc -shared -o libbackhand.so .... -lkstat -ldl -lm

OR

ld -G -z text -o libbackhand.so ..... -lkstat -dl -lm

(The last three tags YOU need to add on).

Try that out :)

Please bear with me for a second....
Are you saying I need to edit apxs or configure to include -lkstat -ldl -lm ??

Yup, I will try to make it a runtime option for configure for a later release,
but I am not to slick with autoconf :)

For now, just change the following line in configure

BUILD_IT="\$(APXS) -o \$(BINNAME) -c \$(SOURCES)"

to:

BUILD_IT="\$(APXS) -o \$(BINNAME) -c \$(SOURCES) -lkstat -ldl -lm"

Then rerun configure --with-apxs=/path/to/apxs
