Building Linux newer version gcc c++11 [Solved]

[zarnce]

I am currently trying to build Poco (Foundation and Net) on Linux (Ubuntu 12.04). I am using a newer version of gcc (4.7.2) that is located in /opt. I copied the build/config/Linux, changed the gcc and g++ paths and then added '-std=c++11' to CXXFLAGS. I then build with the following commands:

./configure --config=Ubuntu --prefix=$(pwd)/package --omit=Data,XML,Util --no-tests --no-samples
make -j 22

I then get the following error:

** Compiling src/RefCountedObject.cpp (debug, shared)

When I build with the built in compiler 4.6.3 it compiles cleanly.

Any ideas?

Thanks

Funny thing that Google - turns out, someone has already figured it out.

Thanks. My searches didn't find that post.

Yet it seems to be a weird answer as I can successfully build with gcc 4.6.3 and '-std=c++0x'. As using gcc 4.7.2 and '-std=c++11' does not work.

Solution:

1) in the Foundation/src/NumberParser.cpp and Foundation/src/NumberFormatter.cpp you need to change "164_FMT" with " I64_FMT". (Place a space after the first double quote)
2) int the build/rules/global file delete $(BINEXT)
3) when using ./configure pass one of the following arguments '--cflags=-std=c++11', '--cflags=-std=c++0x' or '--cflags=-std=gnu++11'

Note: There have been reports of freezing if you use the -j switch.
