Hi,
first timer here. I looked around for about an hour before asking this.
Can't see it discussed anywhere.
What version of gcc is used to build Ardour on linux?
I've just tried compiling a version forked on github today.
This system is: 4.1.12-gentoo
# gcc-config -l
[1] x86_64-pc-linux-gnu-4.9.3 *
It seems the latest source uses C++11, but there's missing "-std=c++11" in
the Makefiles. I believe I have done an "emerge" of media-sound/ardour-3.5.403
on gentoo in the past on another machine, and it built ok with gcc 4.8.4
I just ssh to my old machine and tested ardour3 and see this in the shell.
$ ardour3
bnd txt domain [gtk2_ardour3] to /usr/share/locale
Ardour3.5.403 (built using 3.5-403-gentoo and GCC version 4.8.4)
ardour: [INFO]: Your system is configured to limit Ardour to only 4096 open files
ardour: [INFO]: Loading system configuration file /etc/ardour3/ardour_system.rc
Loading user configuration file /home/ben/.config/ardour3/ardour.rc
No H/W specific optimizations in use
ardour: [INFO]: Loading default ui configuration file /etc/ardour3/ardour3_ui_default.conf
Loading ui configuration file /etc/ardour3/ardour3_ui_dark.rc
Found nothing along /home/ben/.config/ardour3/templates:/usr/share/ardour3/templates
run dialog
Announcement is: Version 4.7 has been released. Update at http://ardour.org/download
So that works. But that was a gentoo emerge.
When i clone my fork on github and run ./waf to build i get this error:

Note the error (marked in bold) at the end regarding -std=c++11
It's tempting to just export CXXFLAGS="-std=c++11", but no doubt that's a bad idea(tm)!
i have a feeling there's something more fundamentally wrong? There's many many warnings
and errors. That was just the first one.
Sorry to ask about gcc version. I see someone on the list did ask it a while ago
and no one answered. (ie. Valerio Orlandini on Fri Jun 4 08:08:10 PDT 2010)
thanks,
ben.
