[Modcplusplus-devel] Apache segfaults w/mod_cplusplus-1.4.3

[Michael S. <ms...@ca...>]

Hi

I managed to compile mod_cplusplus-1.4.3 on Gentoo.

./autogen.sh --with-apxs=/usr/sbin/apxs2
./autogen.sh --with-apxs=/usr/sbin/apxs2
make
cp src/.libs/libmod_cplusplus.* /usr/lib/apache2/modules/
cp include/* /usr/include/apache2/

Apache segfaults when it loads the module.

The end of my apache startup log:

Hi Michael -

couple of questions:

1) have you run 'make check'?  It runs the test cases against your apache
install with the built in config file.  I'd be curious if that segfaults,
too.
2) What MPM are you running (prefork?)
3) Can you send your config file over?  I'll try to reproduce.

Thanks -

John

Re: [Modcplusplus-devel] Apache segfaults w/mod_cplusplus-1.4.3

[Michael S. <ms...@ca...>]

Thanks John

by looking at 'make check' I saw that the problem seems to be the 
CPPHandler that gets loaded by mod_cplusplus. mod_cplusplus loads just 
fine with the 'make check' config.

will now look into the CPPHandler issue. It has been written for 
mod_cplusplus-1.2 and confirmed to work in 1.3, but not 1.4.

Interesting.  Feel free to send the code along, if you'd like - i'll 
have a look.

[Michael S. <mic...@ca...>]

Hi

compilation of 1.4.3 now works fine on my Gentoo system. I created a 
beta quality ebuild for mod_cplusplus-1.4.3 (tested on 4 x86 machines). 
I'm using mod_cplusplus together with SIPfoundry.org's sipXpbx, a 
software PBX for the SIP protocol.

Instructions on how to use my ebuild can be found here: 
http://wiki.calivia.com/index.php/SIPfoundry.org_sipX_Ebuilds_for_Gentoo_Linux

Anyone to test the ebuild and give feedback is more than welcome.
Mike

Re: [Modcplusplus-devel] Apache segfaults w/mod_cplusplus-1.4.3

[John S. <jo...@st...>]

Hi Mike -

The links at http://wiki.calivia.com/index.php/Mod_cplusplus seem to be  
broken - although I find a single patch file at  
http://wiki.calivia.com/svn/sipx-ebuilds/www-apache/mod_cplusplus/ 
files/1.4.3.patch that contains both patches.

I've applied the test_auth.cpp portion (thanks).  For the configure.in  
patch - it would be best to find a more portable way to determine the  
shared library suffix instead of patching it.  On gentoo is libc.so  
somewhere other than /usr/lib?  I can fix configure to look in other  
places for it.

Also, does make install not work for you?  I notice your instructions  
manually copy things in, I will fix that if its not working.

Thanks - Send me the above info and the patches should be applied in  
the next release.  I look forward to more patches!

John

Re: [Modcplusplus-devel] Apache segfaults w/mod_cplusplus-1.4.3

[Michael S. <ms...@ca...>]

Hi John

thanks for pointing out the broken link in the wiki; it's fixed now.

The patch to configure.in solves the issue where libmod_cplusplus.so 
gets built, but make install tries to install libmod_cplusplus.5.

config.log:
configure:19091: checking what the shared library extension is
configure:19094: result: 5
configure:19098: checking for apxs
configure:19115: result: found /usr/sbin/apxs2


 >>> Install mod_cplusplus-1.4.3 into 
/var/tmp/portage/mod_cplusplus-1.4.3/image/ category www-apache
  * Installing libmod_cplusplus into /usr/lib/apache2/modules...
...installing module.......
cp src/.libs/libmod_cplusplus.5 /usr/lib/apache2/modules
cp: cannot stat `src/.libs/libmod_cplusplus.5': No such file or directory
make: *** [install] Error 1

I saw that you fixed the other issue in CVS - thanks.

Mike
