Command: cmake -DWT_WRASTERIMAGE_IMPLEMENTATION=GraphicsMagick
-DBOOST_SIGNALS_NO_DEPRECATION_WARNING=-Wcpp -DWT_CPP_11_MODE=-std=c
++11 ..;make
Note the std level of c++11 and c++0x, I tried both of them, to avoid
confusion the value does not matter, as long as std is set to true, see
below.
I Verified these two version of Wt Examples compiles with cmake and g++
fine under Manjaro Archlinux, so I do not think its a problem with the
Code under some environments, but it is in these.
I have two Ubuntu 12.04 servers both with slightly different specs:
Wt Version: 3.3.2 and 3.3.3 from
http://kent.dl.sourceforge.net/sourceforge/witty/
OS x86_64:
Machine 1: Ubuntu 12.04 LTS #40~precise1-Ubuntu SMP Wed Jun 4
22:06:36 UTC 201
Machine 2: Ubuntu 12.04 LTS #1 SMP Wed Jan 16 18:54:05 MSK 2013
QT: 5.0.2+dfsg1-7ubuntu12~precise1~test4 - qt-default and 5.0.2
+dfsg1-3ubuntu1~precise1~test2 - qt-default
versions: qt4 and qt5 (5.02)
ppa:ubuntu-sdk-team/ppa
Kernels:
1. localhost Archlinux Manjaro virtualbox (VM) Ubuntu 12.04 Desktop
with server
Kernel: Machine 1 = 3.11.0-23-generic
2. myhosting.com Virtuozzo (VM) Ubuntu 12.04 LTS server
Kernel: Machine 2 = 2.6.32-042stab072.10 (requiring
BOOST_SIGNALS_NO_DEPRECATION_WARNING=-Wcpp)
gcc (Ubuntu 4.8.1-2ubuntu1~12.04) 4.8.1 using
ppa:ubuntu-toolchain-r/test
cmake version 2.8.9
BOOST LIB VERSION: 1_55 using ppa:boost-latest/ppa
GNU Make 3.81
Note: Machine 1 and 2 both fail for Same error with g++ (blog), even
though Machine 2 cmake fails at a different point also, they both fail.
g++ command:
g++ -o blog.wt model/BlogSession.C model/BlogUserDatabase.C model/Post.C

Same things to both servers, I did upgrade gcc, if I do not I get the
error: cc1plus: error: unrecognized command line option ‘-std=c++11’,
so it is a moot point about the upgrade, since you can not even compile
it without the switch:
ELSE(HAS_CXX11) MESSAGE("*** Not building widget gallery; C++11
required (gcc > 4.6 + set WT_CPP_11_MODE=-std=c++0x or MSVS >= 2012)")
so I see it requires the WT_CPP_11_MODE=-std=c++0x, where as this works
with c++0x and c++11 in Manjaro Archlinux,
I might point out its a little confusing asking for -std=c++11, yet
requiring -std=c++0x,
and this is the only reason I even mention the version number of std,
but that is a moot point with the error that plagues these two Ubuntu
12.04 servers.
# BOOST_SIGNALS_NO_DEPRECATION_WARNING=-Wcpp why is it that I still get
these warnings even if I define this?
Command for both machines:
cmake -DWT_WRASTERIMAGE_IMPLEMENTATION=GraphicsMagick
-DBOOST_SIGNALS_NO_DEPRECATION_WARNING=-Wcpp -DWT_CPP_11_MODE=-std=c
++11 ..

on Machine 1 I get these errors:

on Machine 2 I get this error during cmake:
c++: internal compiler error: Killed (program cc1plus) Please submit a
full bug report,

I read somewhere that I need to increase my RAM, I have 3 GB, I have
Apache running on this server also, I read they had to increase it to 5
GB, is this True?

Conclusion: The only real difference in Ubuntu servers is the VM's and
kernals
Has anyone ever seen this error?
Does anyone know how to fix this error?
I am stuck at this point, I can not upgrade Ubuntu to 14 its a hosting
service, and my app is based on the Wt-home and blog project and its
failing to compile, as does my app for the same reason.
Thanks
