Apache Module + PB

[Mauro]

Hi,

I'm running Mac OS Tiger (powerpc-apple-darwin8-gcc-4.0.0) and new to C
++ and PB.

I'm developing an Apache module that should generate a response for a
given request, both encoded with Protocol Buffers.

I wrote an example.proto and compiled it into example.pb.h using
protoc. Then I included this example.pb.h in my mod_example.c file.

The matter comes when attemping to make:

make check
source='mod_example.c' object='mod_example.lo' libtool=yes \
depfile='.deps/mod_example.Plo' tmpdepfile='.deps/mod_example.TPlo' \

I tried to change the include paths from /usr/include/gcc/darwin/4.0
to /usr/include/gcc/darwin/3.1 and some other versions available in my
system with same result.

I would really appreciate your help.

Cheers,

Mauro.

It looks like you're running gcc on a .c file, so it's trying to compile as C, not C++. You can either invoke g++ or name your file with one of the recognized extensions: http://gcc.gnu.org/onlinedocs/gcc/Invoking-G_002b_002b.html#Invoking-G_002b_002b

Is there anything you include before realtime-bidding.pb.h in
mod_example.c that might be a broken include ?
Like it contains a declaration of a class that does not have a
semicolon after the final '}' ?

I've never done Apache module stuff in C++ (C only) but I'd guess
thats a good place to look first. I believe there are a few libraries
out there that take some of the pain out of doing Apache modules in
C++, so you might google around for those.

Haha, Jason was right!

I might be getting older... Like I always say. If you write some code,
compile it with the right compiler.

I'll do some research.

Cheers!

Mauro.

modcplusplus is right solution for voiding such headaches.

I've no problem with modcpluplus + ( C++ Module ) + any c++ shared objects except PB.

I explained my problem recently in this group.
