Error: ISO C + + does not allow the initialization of a very static member within a class
starting today to learn C + + primer, when involved in the sales_item.h header file, there are some problems (and c++11 new features related), the current compiler version is gcc/g++ 4.6.3, so need to upgrade. You can use the PPA to upgrade to 4.8.1, as follows:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update; sudo apt-get install gcc-4.8 g++-4.8
sudo update-alternatives--remove-all gccsudo update-alternatives--remove-all g++
sudo update-alternatives--install/usr/bin/gcc gcc/usr/bin/gcc-4.8sudo update-alternatives--install/usr/bin/g++ g++/usr/bin/g++-4.8
sudo update-alternatives--config gccsudo update-alternatives--config g++
g++--version
