[openamq-dev] Using the static OpenAMQ libraries in a sharedlibrary seems impossible, except on i386 platforms...

[Jacobus Geluk]

FreeBSD, as a BSD based operating system, seems to be a bit different in
this area than Linux, since I can't get it to work, yet. :-)

Using -fPIC seems to have a 5% performance overhead anyway (source: apache
web site), so it would be a good idea if the OpenAMQ build procedure could
generate multiple versions of the libraries, not only
singlethreaded/multithreaded and release/debug but also static/shared and
static+-fPIC-for-use-in-other-shared-libraries. Different names for each
version of the library, like boost does, would make it possible to have
multiple versions installed like libamq_wireapi_mt_debug_pic.a.

I keep digging, but I am also trying to create a workaround, since I expect
more problems anyway, since both Apache and OpenAMQ are based on their own
versions of APR. The workaround would be to have the apache module
"mod_amqp" talk via shared memory and/or socket and/or pipe with a companion
daemon that does the actual work (and can be build in C++).
