5 years ago The library requires some boilerplate to get initialized:
- Whenever the library needs to log something, it needs a way to know how to do that. So the first thing you should always do is provide a logging function via the
log_initfunction:/* This will be your custom logging function */ static void my_dbg_logger(const char *str) { XPLMDebugString(str); }
PLUGIN_API int XPluginStart(char name, char sig, char desc) { ... /
- Tell libacfutils to use your logging function, and also what
- prefix to use for your plugin name. / log_init(my_dbg_logger, "my_project_name"); / If you want to use the crc64-based fast PRNG, initialize it too */ crc64_init(); crc64_srand(time(NULL)); ... }
PLUGIN_API void XPluginStop(void) { ... / No more libacfutils calls after this! / log_fini(); }
2. That issue with ``__imp____iob_func`` is because VS2015 changed how Microsoft exposes certain stdio pointer definitions (and MinGW still uses the older method). To get this going, you need a bit of glue code in your plugin build on VS. I have provided the glue code in the library here: https://github.com/skiselkov/libacfutils/blob/master/msvc_compat/lacf_msvc_compat.cpp
You will want to include this file in your project to be built into the resulting binary.
3. libacfutils uses a special multi-threaded mod of GLEW (GLEW-MX), which is a bit more complicated to set up on Windows. On Linux & Mac, just calling ``glewInit`` is enough. However, on Windows you will also want to add some ``DllMain`` hooks. The above msvc compat file already contains the necessary code. However, if you already have a ``DllMain`` function in your plugin, you will want to disable that functionality from the compat file. To do so, define the ``_LACF_DISABLE_DLLMAIN`` macro and make sure you replicate the contents of the ``lacf_glew_dllmain_hook`` function inside of your ``DllMain`` (you basically need to call a couple of libacfutils functions on certain events): https://github.com/skiselkov/libacfutils/blob/master/src/glew.c#L46-L60

Hey, I built the dependencies and then build a redist version for Linux with Ubuntu 18.04.After that I put my include directory from acfutils in my include direction for my project and add the libs folder to my library search paths in Visual Studio 2019.When I try to load shaders, xplane just crashes with an abort().I initialized GLEW with glewInit() and after that I tried to load shaders from text with
shader_prog_from_text_v(const char *progname, const char *vert_text, const char *frag_text, const shader_attr_bind_t *binds)but then xp just crashes.Another thing is that when I try to use the log class, visual studio throws the errorunresolved external symbol __imp____iob_funcfor the log_backtrace function.Are their any known solutions for my problems ? :)
