Overview
Each target library is created separately as a shared library in the modules folder. This allows NIDs generation at build time and a clean code separation.
The Emulator loads the libraries on demand and resolves the symbols etc. A library does only communicate with the emulator. If it should need information/calls from other libraries, a separate top class should be used. The library can link against it and access the interface.
Planned is a core library for such cases and for the interfaces currently in the emulator.
Create a new module
- duplicate the template folder
- replace the folder with the identical name of the target library.
- inside CMakeLists.txt, replace template in "set(libName template)" with the library name
- inside entry.cpp, replace "libSce" both in LOG_DEFINE_MODULE() and MODULE_NAME = ""
All exported function are placed inside the provided extern "C" scope and should start with "EXPORT SYSV_ABI", since those functions are called directly by the emulated application (Linux).
After a new CMake config, the new library should be picked up and built.
Build: dll2Nids may print an error. Just add a dummy function with a long name (11 + extra space).
Normally, only names starting with sce or _sce are converted. Use one of the following macro, defined in common.h, for everything else:
__NID(func) : converts the function name
__NID_HEX(hexId) : If the function name is unknown, use the hexId instead
