I had a quick look, but I find no indication of that in configure.in or any of our m4 files. I wonder how that comes into play. Maybe something autoomatically triggered by the libtool used or by the gcc self-report. I must admit: Currently no idea. But Mladen is of course right: no use for gcc during make and we should be able to remove the need from the configure script, only that I have no idea how.

I don't think C can parse that.

I've taken another look and it seems that the places where extern C is used are all in the PCRE package and already have #ifdef __cplusplus surrounding them. -chris signature.asc Description: OpenPGP digital signature

I did some quick checking and it doesn't look like mod_jk requires a c++ compiler for any actual compilation -- that is, everything is declared as extern C and no obvious c++ features in use. httpd advertises requirements for autoconf, libtool, and an ANSI-C compiler (not C++). I didn't actually try to build httpd without having c++ available. Is this simply an oversight in the configure script? Are we stupidly requiring a C++ compiler, or is there a reason that it is required? I was just able to build mod_jk on Amazon Linux (roughly RHEL) by: 1. Installing http-devel and gcc-c++ packages 2. Running configure 3. Removing gcc-c++ and gcc46-c++ packages (this removes the C++ compiler) 4. Running make This resulted in a .so file that I have not actually tried running (in httpd), but have every reason to believe would work just fine. I think this is just an erroneous requirement of configure. Can anyone give me some pointers for how to modify the capabilities-scanning that configure does? -chris signature.asc Description: OpenPGP digital signature
