How to build .so, .dylib, .dll at one machine?

[wiedymi]

Hello! Is it possible to build the library into three platform format on Mac? so, .dylib, .dll
Also I would like to have those files built in different platform architecture, so .dylib should universal, not only arm64.

Is it possible to build the library into three platform format on Mac?

If there are suitable cross-compiler available on macOS, likely yes.

Building libass works the same as any other Autotools (here: Autoconf, Automake & libtool) project.

To build for your current macOS machine, run ./configure and then run make. Then if you want to install it in /usr/local, run make install.
To cross-build for other platforms, you probably need to tell configure what platform you’re targeting with --host and what compilers to use etc.

Nothing about cross-compiling or “universal dylibs” is libass-specific and you'll likely have more luck finding useful info with a web search for macOS cross-compiling and universal dylibs than on this issue tracker.

I see, I've tried to use --host, but I still get .dylib instead of .so built.

Command I run:

./configure --host=x86_64-linux
./make -B

Ok, I've built it, but there's missing libass.so.9.1.4
