Hi John, Thanks for your fast reply! > I'm CC-ing the mod_cplusplus users list (we can take it off users@httpd > if you like). I can help out later today on this, in the mean time can yo= u > send me the version of apache and mod_cplusplus you are using (from cvs?)= . Ok. I sent the mail to the httpd list because I saw little activity on the mod_cplusplus, sorry... But now modcpluspus-users seems more appropriate (and I subscribed). I'm using apache 2.0.40, the latest available version (I think so) from www.apache.org. mod_cplusplus is version 1.0.2 ("Apache2_GA4"), from your page at SourceForge. There are more details about my system in the first message below. Now that you have been so kind to answer, I'll send you more specific information about my efforts, hope I don't bore you :) This are the lines I added to httpd.conf to test my module and your samples: ---begin LoadModule cplusplus_module modules/libmod_cplusplus.so LoadCPPHandler hello_world modules/libmod_HelloWorld.so LoadCPPHandler test_handler modules/libtest_handler.so LoadCPPHandler test_input_filter modules/libtest_input.so <Location /hello-world> SetHandler hello-world AddCPPHandler hello_world </Location> <Location /test-handler> SetHandler test-handler AddCPPHandler test_handler </Location> AddCPPConnectionInputFilter test_input_filter <Location /test-input> SetHandler cpp-handler AddCPPHandler test_input_filter </Location> ---end I think they are correct (?), as I said, because everything works with "-X". I tried only some of them, as I explained (only one c++ module at a time), and the result is the same. Loading only mod_cplusplus.so works fine, but I can't do any AddCPPHandler. My module is VERY simple: ---begin #include "apache_handler.h" class mod_HelloWorld : public ApacheHandler { public: mod_HelloWorld( void ); ~mod_HelloWorld( void ); int handler( ApacheRequestRec *pRequest ); }; extern "C" cpp_factory_t hello_world; mod_HelloWorld::mod_HelloWorld() : ApacheHandler() { fprintf(stderr, "foo\n"); // or whatever... } mod_HelloWorld::~mod_HelloWorld() { fprintf(stderr, "bar\n"); } int mod_HelloWorld::handler( ApacheRequestRec *pRequest ) { pRequest->content_type( "text/html" ); pRequest->rputs( "<HTML>\n" ); pRequest->rputs( "<TITLE>M=F3dulo Hello World</TITLE>\n" ); pRequest->rputs( "<H1>HELLO WORLD</H1>\n" ); pRequest->rputs("</BODY></HTML>\n"); return OK; } ApacheHandler* instanciate_HelloWorld() { return new mod_HelloWorld(); } cpp_factory_t hello_world =3D { instanciate_HelloWorld, NULL, NULL, NULL, }; --end I compiled it by hand (-fPIC, -shared to gcc...) and by modifying the Makefiles in your samples. In both ways the result was the same :( Everything works and I can see the "Hello World" with -X, as I said. Any hint? Thank you very much again for your help. Pachi. PS: It's late now here, so I'm afraid I won't be able to respond very quickly if you need any other information... I'll check mail early tomorrow. > >-- Original Message -- > >Subject: httpd crash at startup with custom c++ (mod_cplusplus) module > >From: Pachi Sucunza <pa...@sc...> > >To: us...@ht..., jo...@st... > >Date: 26 Aug 2002 16:45:38 +0200 > > > > > >Hi everyone > > > >I have written an Apache module in C++ (using mod_cplusplus... > >http://modcplusplus.sourceforge.net/ ) > >The problem is that I can't get any C++ module working, the httpd proces= s > >dies right after initialization, without any complaint or message (in st= dout > >or any of the log files). > > > >I'll try to explain more thoroughly the situation: > >- I'm running Linux - Debian 2.2 (potato), kernel 2.2.19-smp on a 2x1GHz > > Intel Pentium III.
