NOTE: we have the policy to always support current Debian/stable
amd at least one Ubuntu LTS release, unless hard dependency problems prevent that.
Currently, Ubuntu/Trusty is already a bit dated, but the only problematic dependency
could be libboost (1.54 in Trusty, 1.55 in Jessie).
GCC-4.8 can be replaced by GCC-4.9 in Trusty without problems
It is always a bit tricky to find out the precise lower boundary,
so we try to upgrade these requirements as our platform progresses.
For now we have used the level available on Ubuntu/Trusty to set
the lower constraints for most libraries
This means we have rather tight compiler requirements now.
Beyond that, we expect no serious impact; the most notable
C++14 feature we're likely to use soon is type inference
on lambda arguments.
the corresponding requirements are already reflected in the
SCons build, see Platform.py
NOTE: the current debian package is still based on the preview
Release 0.2.pre from last year. It will be upgraded probably after
the transition to Jessie as reference system
The XV-Viewer widget in our GUI uses four direct calls
to the X-Lib. This was discovered by strict dependency checking,
as mandated by new Debian policy
Note: this drops some backwards compatibility. We're targeting now
roughly the range between Ubuntu-Precise (LTS) and Debian/testing,
with Debian/stable as the reference system.
The naming scheme for Boost-Libraries was adjusted with Boost-1.42
for Unix-Platforms. Now the '-mt' suffix isn't included any more, but
the libraries available through the usual packaging mechanisms can be
assumed to be thread safe.
