Why would the "-Wl" option cause problems?

[Marcus Leon <Ma...@baltimore.com>]

We've isolated the code in the linking command that causes our Apache 2 C++
modules from loading correctly.  

Bad: gcc -shared -Wl,-soname -Wl,mod_enforcer.so -o .libs/mod_enforcer.so
Good: gcc -shared -o .libs/mod_enforcer.so mod_enforcer.o

Why does the -Wl option cause problems?

Why is everything OK with .c files but not with .cpp files?

Is anyone able to build C++ modules using the Apache 2 tools?

The -Wl option is in libtool.  For various reasons we do not want to edit
this script.  It appears that this option is hard coded in libtool and there
are no switches that can remove it.

Thanks

Subject: Problems building C++ modules for Apache 2.0

Hello, we modified our apxs to build C++ modules but we get an error when we
start Apache.  The peculiar thing is that this file builds and runs fine
when you give it a .c extension.  It's only the c++ file that causes
troubles.  Does anyone have any suggestions?

The error is:
Syntax error on line 232 of /home/mleon/apache2/conf/httpd.conf:
Can't locate API module structure `enforcer_module' in file
/home/mleon/apache2/modules/mod_enforcer.so:
/home/mleon/apache2/lib/libapr.so.0: undefined symbol: enforcer_module

Thanks
