Documentation about building libxmp-lite #137

Open mmontag opened 5 years ago

mmontag commented 5 years ago

I'm trying to build libxmp-lite static/shared library (not an executable) with Emscripten and my understanding of GNU Make is not good enough to prevail. I am very confused.

Can you provide some documentation about how to build libxmp-lite static/shared library (compatible with Emscripten)?

To target Emscripten LLVM bitcode, you are supposed to invoke ./configure and make with Emscripten prefix: emconfigure ./configure and emmake make (this sets emcc as the C compiler, among other things). This requirement seems to break things when I try building libxmp-lite in various ways.

Hi Matt,

Try the following parameters:

$ emconfigure ./configure --enable-static --disable-shared $ emmake make

Here it resulted in:

... CC src/loaders/s3m_load.o CC src/loaders/it_load.o AR lib/libxmp-lite.a /usr/bin/llvm-ar: creating lib/libxmp-lite.a /usr/share/emscripten/emranlib lib/libxmp-lite.a

I don't know much about emscripten so I didn't really test the resulting library to see if it works, but please let me know if you have more problems.

Hi Matt,

I check that and report back ASAP.

Quick question, where do I run these commands?

Oh oops, sorry, I think the other email slipped under my radar. These are simply directories used by the source tree, you can't really run those.

You may want to have a look at this: https://github.com/wothke/libxmp-4.4.1 (It's an emscripten port of an older version of libxmp).

Best regards, Claudio

I've partially documented my experience here: https://github.com/mmontag/chip-player-js/#subproject-libxmp-lite
