[opensource-dev] Building the viewer after the latest commits

[Nicky Perian]

Yes. I agree, It does cause problems for older distros. I have been balancing the old / new distro support for some time. If I provide the old then the new users complain about every time I start libxxx.so library is missing. In some cases I provide a newer libxxx.so in the viewer package but that causes problems to as the next distro upgrade may have deprecated or removed support for libxxx.so and some distros (opensuse) nag about it.  

For a while I was building on gcc-4.6.5 on squeeze for release and then gcc-4.7 for test version in order to cover both old and new. I suspect I'll go back to that soon.

>>Hopefully not !... The current Linux builds of the viewer and pre-built libraries are
compiled with gcc 4.6, which also imposes a minimal requirement on
the target systems' libstdc++ version (6.0.16). If LL were to provide pre-built libraries compiled with gcc v4.7,
then the "old" (like 2 years old *only*) Linux distributions would
become incapable of running the resulting viewer. You should instead keep a partition (or a VirtualBox virtual machine)
with a build-system matching LL's one (i.e. using gcc 4.6.4 and its
associated libstdc++). Henri.

    expect to start a toolchain update for Windows (to VS 2013) and Mac
    OSX (to Xcode 5, clang) shortly, but don't plan to change Linux (it
    was updated much more recently than the other platforms as part of
    the Sunshine project).
