I'm extending our project [1] with some native extensions. Our code is
written (currently) all in C++, and we use Swig to provide Ruby
bindings.
For the extconf.rb file previous I've just had:
---8<[snip]---
require 'mkmf'
create_makefile('nonblockio')
---8<[snip]---
However, now I'd like to customize the file a little more in order to
support both Ruby 1.8 and 1.9. Between those two versions of Ruby we
have a different set of header files that are required. So, anyway,
I've added the following the check for headers:
Tried it but no joy. In the mkmf.log I'm not seeing where it's using
g++ instead:
have_header: checking for qpid/messaging/exceptions.h... -------------------- no
"gcc -E -I. -I/usr/lib64/ruby/1.8/x86_64-linux
-I../../../../ext/nonblockio -DRUBY18 -O2 -g -pipe -Wall
-Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector
--param=ssp-buffer-size=4 -m64 -mtune=generic -fno-strict-aliasing
-fPIC conftest.c -o conftest.i"
In file included from /usr/local/include/qpid/messaging/exceptions.h:26:0,
from conftest.c:1:
/usr/local/include/qpid/types/Exception.h:25:18: fatal error: string:

compilation terminated.
checked program was:
/* begin */
1: #include <qpid/messaging/exceptions.h>
/* end */

There was an error, but it turns out that additional error was my own
fault; i.e., I had created a copy of conftest.c to play with some
commandline arguments and then forgot to delete it from the extension
directory. I'm now good to go.

and it got further than before.
Still sounds as if you have an error?
