[Ardour-Dev] g++ version and -std=c++11 ?

:-) Hey Paul
thanks for the quick response.
ok cool.. Yes, vers 3.5.403 is what's "current" in Gentoo (fyi).
When a user runs "emerge ardour" that's what installs.
vers 4.7 is the reason i'm looking to fork from github & compile instead.
For what it's worth, I could not successfully compile on linux.
As per my previous post, it dies at:
[ 47/811] cxx: libs/lua/luastate.cc -> build/libs/lua/luastate.cc.1.o
However! this following hack got it Ardour to compile:
$ git diff wscript
diff --git a/wscript b/wscript
index 926e6fe..fef8b18 100644
--- a/wscript
+++ b/wscript
@@ -438,6 +438,13 @@ int main() { return 0; }''',
# determine processor flags via /proc/cpuinfo
#
+ #
+ # HACK
+ # add cxx_flags.append('-std=c++11') anyway
+ # [ben 20Apr16]
+ ## cxx_flags.append('-std=c++11')
+ compiler_flags.append('-std=c++11')
+
if conf.env['build_target'] != 'i386':
flag_line = os.popen ("cat /proc/cpuinfo | grep '^flags'").read()[:-1]
I won't be checking this in. It's just a HACK. I just wanted to see if it would
produce a successful compile. It did. It simply added the compile flag '-std=c++11'.
hope that's useful info?
cheers,
ben.

Oh, and please don't ever use the 3.5.403 version. We're at 4.7 for a reason (or many, many reasons to be more precise).

Ardour is *not* written in C++11. We use a variety of compilers (gcc4, gcc5, clang, apple gcc).

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

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.
