>Description:
Given a module with a configuration like this, APACI configuration finds that it
does need to link the additional libraries:
* MODULE-DEFINITION-START
* Name: mysql_auth_module
* ConfigStart
MYSQL_LIB="-L/usr/local/lib/mysql -lmysqlclient -lm"
if [ "X$MYSQL_LIB" != "X" ]; then
LIBS="$LIBS $MYSQL_LIB"
echo " + using $MYSQL_LIB for MySQL support"
fi
* ConfigEnd
* MODULE-DEFINITION-END
This works fine when this module is compiled statically. However, if you make
this module --enable-shared during the config, then the resulting .so file does
not
have the additional libraries linked, but those libraries are referenced for
linking
when building httpd.
I believe that the libraries found to be linked for specific modules this way
should
be used when building the .so file, not when linking httpd if that module is
marked
to be shared.
>How-To-Repeat:
Configure apache with a dynamic module that needs extra libraries as specified
above.
>Fix:
Don't configure such modules during the initial build, but afterwards, using
apxs.
