Hi Rallaz,

Wow. Thank you. It is pretty far over my head unfortunately.

Can you do a devtoolset-1.1 which has g++ and which accepts -std=c++11?

http://ftp.scientificlinux.org/linux/scientific/6rolling/x86_64/external_products/devtoolset/

To fire it up, you have to do a
scl enable devtoolset-2 'bash'
In your command window.

I got this far and had to give up:

# rpmbuild --rebuild librecad-2.0.4-1.fc19.src.rpm
...
lib/filters/rs_filterdxfrw.cpp: In member function 'virtual void
RS_FilterDXFRW::writeHeader(DRW_Header&)':
lib/filters/rs_filterdxfrw.cpp:1479:22: error: 'class DRW_Header' has no
member named 'addInt'
data.addInt(it.key().toStdString(),
it.value().getInt(), it.value().getCode());

Others told me I need a newer libdxfrw

Many thanks,
