Using a C++ class in C source file

[Laszlo]

Hi all,

I created a C1.hpp and C1.cpp, compiled and linked into a C1.a
file. I did copy the C1.a file into /usr/local/apache2/lib and
C1.hpp into /usr/local/apache2/include. This class provides
some usefull methods to process a request.

OK. Now I would like to use it in my module mod_xyz.
Entering the command

/usr/local/apache2/bin/apxs -c -i -a mod_xyz.c

returns these lines:

/usr/local/apache2/build/libtool --silent --mode=compile gcc3
-prefer-pic
-DAP_HAVE_DESIGNATED_INITIALIZER -DLINUX=2 -D_REENTRANT
-D_XOPEN_SOURCE=500 -D_BSD_SOURCE

-I/usr/local/apache2/include
-I/usr/local/apache2/include -I/usr/local/apache2/include -c -o
mod_xyz.lo mod_xyz.c && touch
mod_xyz.slo

..

How can I fix it?

You cannot have a C++ class in a C source file. Just rename the .c file
to
..cpp and compile again.

Also need to be careful about sharing globals between C and C++. Use
extern "C" in C++ code for any variables that are shared with C code.
