Hi, I have a problem. I have downloaded Apache 1.3.14, Mod_perl 1.24_01, PHP 4.0.3pl1, mod_fastcgi 2.2.8, and untarred all of them. I configured Apache with mod_so enabled, installed it, then installed all the three modules as DSO with apxs. Then I found that I cannot access any Mod_perl, PHP, or FastCGI programs, if I try, I will get an error, and the error.log of Apache will have a line like: "[...][notice] child pid xxxxx exit signal Segmentation Fault(11)" If I comment out the "LoadModule perl_module libexec/libperl.so" line from httpd.conf, then I can access FastCGI and PHP programs, but if I include it, then I will not be able to access any of them, nor am I able to access Mod_perl programs. Then I compiled Mod_perl as a static module of Apache, and installed it, then installed mod_fastcgi and PHP as DSO. This time, Mod_perl programs and FastCGI programs can be accessed, but PHP programs will produce the same errors as above. So it seems that Mod_perl is conflicting with these two other modules, especially PHP. Can anybody give me some help and advice on this? Thanks a lot! Di, Yu 11.13
