I've been working on some PHP extensions that were written in C++ for a while now. I wrote the original stuff a while back, and since I have no great desire to re-write them in C, I decided to just go ahead and use the C++ instead. PHP and Apache are both written in C, so there are going to be some obvious pains involved in getting C++ to work properly with the C base. (extern "C"'s, linkage problems, etc.) I managed to get everything to work eventually, but not without a fair amount of hair pulling and whimpering. In the end, this is the procedure I came up with: -- take the library I wrote in C++. Extern "C" a lot of stuff so C code can see it properly. -- use ext_skel to make the extension skeleton. -- write a wrapper for the C++ in C with the stuff the ext_skel produced. -- modify the config.m4 file ext_skel produces by adding a PHP_REQUIRE_CXX line. Now, for some reason, adding PHP_REQUIRE_CXX doesn't seem to do much, so I'm probably not using it correctly. Even after adding it, I still need to manually edit config_vars.mk so that it reads: CXX = g++ CXXFLAGS = -g -O2 I don't know why. -- modify the Makefile/Makefile.in files to see the new library that's about to be created by adding LTLIBRARY_OBJECTS_X = whatever.lo -- compile PHP, compile Apache. Compiling PHP is fine, as the C++ files are done with g++ (or C++ compiler X) and the C files with gcc (or whatever C compiler). Apache starts to compile fine, but when it hits PHP, it starts complaining about invalid function prototypes and such, especially if I use the STL or anything of that sort. At this point, I have to continue compiling Apache with a C++ compiler, which is easy enough. (I usually just change the compiler in the apache_path/src/Makefile file by changing "CC=gcc" to "CC=g++".) Unfortunately, I can't seem to automate this. So my question is: is there an easier way? I don't mind having to do all of this stuff now, but if I have to do it a bunch of times, it's going to start sucking. Thanks. J Smith pseudo "code, dba and linux guy" Tutorbuddy Inc.
