Profile

If you are using GCC compiler >= 5.1, Conan will set the compiler.libcxx to the old ABI for backwards compatibility. In the context of this getting started example, this is a bad choice though: Recent gcc versions will compile the example by default with the new ABI and linking will fail without further customization of your cmake configuration. You can avoid this with the following commands:

# generates default profile
conan profile new default --detect

# sets libcxx to C++11 ABI
conan profile update settings.compiler.libcxx=libstdc++11 default 
conan profile remove settings.compiler.libcxx default

cat ~/.conan/profiles/default
ls -la ~/.conan/profiles/
