Problems building C++ modules for Apache 2.0

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

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

my first thought is that by changing the extension, you affect how the 
compiler treats the file. the file is either a C module or a C++ module 
depending on its extension. if this is the case (it may or may not be, 
depending on your compiler), you've probably affected the linkage, and 
this symbol isn't linked properly. is this symbol surrounded by #ifdef 
_CPP or 'extern' linkage specificiers?

what platform/ compiler/ etc..

cheers,
andy
