I want to build the module as a DSO. I can get the module to load by using LoadFile to pull in the C++ runtime first; but the constructors on global objects (e.g., cerr) don't get invoked. >How-To-Repeat: Build a module in C++ and have it print messages to cerr. If necessary, I can write you some example code. >Fix: Yes, I have a fix: I added two dummy C++ files to the Apache build (two so that one can call into the other and make the linker think it's being used) and linked httpd with g++ instead of gcc. This worked fine (the module still has to avoid using any global objects with constructors of its own, but that'll have to do).
I have put together a patch to the configuration scripts to add this fix if (and only if) configure is invoked with "--cplusplusmodules". It picks a C++ compiler just the way it normally picks a C compiler. It does not affect the compilation of C files. The patch is available at <http://www.thibault.org/cplusplusmodules.tar.gz>. The tarfile contains: * Output of "diff -r -C3 dist patched" (where dist is the distributed source of 1.3.3, and patched is my modified version) * patched/src/dummy.C * patched/src/dummy.H * patched/src/dummy2.C (where the last 3 are the dummy C++ files used) >Audit-Trail: >Unformatted: [In order for any reply to be added to the PR database, ] [you need to include <[EMAIL PROTECTED]> in the Cc line ] [and leave the subject line UNCHANGED.
