Problem with compiling mod_perl

[Craig Vincent]

I must have now installed mod_perl a dozen times on a dozen machines and this is the first time I've come across this problem and I can't seem to solve it...nor have I had any luck through FAQs, DejaNews or even newsgroup postings :(   I have an RH Linux 6.1 box.  I currently have Apache 1.3.9 running on the server.  My problem is when I attempt to compile mod_perl...this is what I get...   <snip> SSL_BASE=/usr/local perl Makefile.PL EVERYTHING=1 DO_HTTPD=1 Appending mod_perl to src/Configuration Using config file: /usr/home/sysadm/mod_perl-1.21/src/Configuration Creating Makefile  + configured for Linux platform  + setting C pre-processor to gcc -E  + checking for system header files  + adding selected modules     o ssl_module uses ConfigStart/End       + SSL interface: mod_ssl/2.4.9       + SSL interface build type: OBJ       + SSL interface compatibility: disabled       + SSL interface experimental code: disabled       + SSL interface vendor extensions: disabled       + SSL interface plugin: Configured DBM (-ldbm)       + SSL library path: /usr/local       + SSL library version: OpenSSL 0.9.4 09 Aug 1999       + SSL library type: installed package (stand-alone)       + SSL library plugin mode: none  + enabling Extended API (EAPI)  + checking sizeof various data types  + doing sanity check on compiler and options ** A test compilation with your Makefile configuration ** failed. This is most likely because your C compiler ** is not ANSI. Apache requires an ANSI C Compiler, such ** as gcc. The above error message from your compiler ** will also provide a clue. </snip>   This DOES NOT happen if I attempt to compile Apache on it's own...this error only occurs when I attempt to do an HTTPD build through mod_perl.  Now the one thing I have discovered is 95% of the time the test compilation error is not because of the compiler not supporting ANSI (I'm using the latest gcc btw) but is just something failed in the compiling whether it be a configuration error, problem running a function etc...  The main problem is that I don't receive any additional error messages so I don't know what the real problem is.  I have also tried using gcc with the -ansi switch as well just to be on the safe side but that didn't help either.   Has anyone ever encountered anything like this before?  Or have any ideas on what may be causing this error?   Sincerely,   Craig Vincent
