# This patch applies C++ name mangling to all of OpenAL Soft's functions so that they don't conflict with the functions in Emscripten's OpenAL implementation.
|
||||
# Otherwise, the Emscripten build crashes on startup because the Emscripten version of RetroArch also depends on OpenAL, and it will incorrectly try to use our OpenAL implementation instead of Emscripten's.
