Debugging a Trusted Plugin

In some cases it can be useful to develop/port your Native Client module using a two-step process, first as a non-portable trusted Pepper plugin for Windows, Mac, or Linux, then porting to Native Client. In particular this approach allows you to use the standard debuggers and tools from your preferred desktop operating system during trusted plugin development.

Developers should be mindful of the following potential issues when planning this course of development:

• Some libraries commonly used with Native Client will not build easily on all operating systems.
• Threading models differ between trusted Pepper and untrusted Pepper implementations.
• Extra effort may be required to get source to compile with multiple different compilers, for example GCC vs. MS Visual Studio.
• Certain operations such as platform-specific library calls and system calls may succeed during trusted development but fail in Native Client.

With this in mind, these sub-pages provide some tips on working with trusted Pepper plugins on Windows, Mac and Linux.
