Application vs. Toolkit platforms: Compiler support
For products which are C++ toolkits, the compiler is an important aspect of the platform. Typically the compiler used by the customer must correspond precisely with the compiler used to build the toolkit. As with application platform support, the goals remain the same: to effectively support software users in a dependable way, balancing commercial and technical issues.
Similarly, toolkits wrapped for use with Python, Java, or other languages will require specificity in the installed development environment.
Due to the use of C++, and the lack or instability of a standardized C++ ABIs on many operating systems, versions of the toolkits are provided for different compilers, and even different compiler versions. Typically, toolkits are available for the system's native C++ compiler, and also for a more current GNU g++ version.
