Hi,

that worked. Now that needs to go into the official sources...

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++).

I don't want to miss an opportunity to agree with Henri...

At present, our standard Linux build environment for Linux is Debian 
Squeeze, gcc 4.6.  That's what we'll build the packages for. We 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).


You are of course welcome to use what you want for your builds, but we 
won't be making changes to the packages we provide in order to support that.

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.

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

[Lance Corrimal]

Well, my build environment for this kind of stuff in fact *is* a debian 
squeeze 6.0.10 running on KVM, and the gcc available for it is 4.4.5, not 
4.6.x:

debian-build-6-2:~$ cat /etc/debian_version 
6.0.10
debian-build-6-2:~$ g++ --version
g++ (Debian 4.4.5-8) 4.4.5

There is no newer gcc available for that version, so I dunno what the lab is 
doing there. It might help if the "official linux build environment asccording 
to LL" was properly documented somewhere on the wiki.

Cheers
LC
