compile a file written by C++ into apache
Hi,
I write a module by C++ supporting the generation of SAML assertion, so in my module I called the OpenSAML Library.The question is how I compile this source file written by c++ language into my apache server.
Please help me.Thanks a lot at first!
Regards,
Jia

Hi, Noordhui,
Thank you for your reply.
Because OpenSAML which I called is a set of open source C++ & Java libraries and large ,so I want to write a module with c++ ，in which I can call the library-function directly.Can you give me some help how I compile module written by c++ into apache DSO file.I used apxs tool but it failed.This tool can't compiling c++ source file？？？If using g++,is my directive correct??(g++ -fPIC -shared -o mod_validate.so mod_validate.cpp -I/usr/include/httpd -I/usr/include/apr-1 -I/opt/opensaml/include) .
Because I am just studying apache module development, I hope get more help.Thanks for your concern!
Regards,
Jia

Ohahaha,
Eric Covener,Thank you!
You are right ! I download 30-Nov-2010 apache source code. Indeed It is modified in trunk .

I believe this was reported and fixed in trunk over the last month or so.

new is a C++ keyword. Three solutions.
1. Rename the parameter in http_config.h to new_conf. Bad.
2. At the top of your source file add "#define new new_". Bad.
3. Make your module C only. Split off the C++ code into a separate file. Good.

Thank you for your replay,
In Apache2.2, I compile a c++ source file with g++ as below：
g++ -fPIC -shared -o mod_validate.so mod_validate.cpp -I/usr/include/httpd -I/usr/include/apr-1 -I/opt/opensaml/include
After it , I copy mod_calidate.so into apache module location ,and this module work well.
But now,in apache2.3,I compile this file in the same way.it accurs the following error,
/apache2.3/include/http_config.h:989:error:expected ","or "..." before ‘new’
(In headers file ,The 989th line is:
AP_DECLARE(void) ap_merge_log_config(const struct ap_logconf *old,
struct ap_logconf *new);
)
I think there are not errors in this line ,but why can i compile it successfullly?
Thank you,
Jia

Like you compile any mixed project: define a function in your C++ code
with C linkage[1] and call it from your C code. Compile .c and .cc
files to object files, then link them into a shared object.
apxs2 probably won't be much help here, it doesn't seem to handle C++
source files (at least, it never does in my projects).
[1] extern "C" void entrypoint(void *data) { /* ... */ }
