T773:orkaudio: compile under Ubuntu 18.04 & OpenSuse Leap
-- add conditional support for xerces 3 if we are on an ubuntu
or opensuse system.
xerces2.8 will continue to be used under Centos 6/7 and
windows.
-- in silk codec,cast timestamps to long before computing interval
With GCC 7.3, compiler complains about computing abs(t2-t1) if t2 and
t1 are unsigned ints. In this case we are invoking abs() on an unsigned
int, which is seen to be ambiguous.
Casting "unsigned int" to "long" range extends the unsigned int, so that
a difference can be computed correctly without overflow.
T763: orkaudio: use -fPIC for all components Since -fPIC seems to be recommended for use on all code that uses shared libraries, use it everywhere.. This corrects a shared library load error on Centos6 that is related to the Centos6 version of APR using RTLD_DEEPBIND inside apr_dso_load.
T746:orkaudio: replace ACE cross-platform compatibility layer
The general idea is that ACE is not as popular as APR and is showing
its age. Linux distributions do not package ACE by default, so it has
to be built every time orkaudio is deployed to a new Linux distribution.
ACE functionality is being replaced by native C++11 features, and
by the Apache Runtime library(APR).
APR powers various open source projects such as apache, freeswitch,
log4cxx and subversion.
Features that are being replaced by native C++11:
semaphores
mutexes
threading
file operations
Features that are being replaced by APR:
timers
networking
dynamic shared object loading (loading .dll and .so files)
