Tips and tricks
You can use these tips to help resolve some of the issues that you might encounter as you port your apps to BlackBerry 10.
- Some standard C++ libraries include a bug where types that are defined by the library are imported into the global namespace. This bug can make porting difficult if you try to link against a standard library implementation, such as Dinkum (the default for the Native SDK), which doesn’t have that bug.
- Including a C++ library header file may promote external names declared in the std namespace into the global namespace as well, with individual using declarations for each name.
- In some environments, the C standard header files include no namespace declarations, declaring all names directly in the global namespace. This practice is in violation of the C++ standard.
Using older code
There are some older variants of C++ code out there, so you can choose to switch the runtime to C++ Dinkum (which the Native SDK uses) or use the compiler switch -Y_gpp to tell the compiler that the app is nonconformant.
