minifb: unsupported on wasm/wasm32

[konsumer]

Xmake Version

2.9.5+20241026

Operating System Version and Architecture

Mac Catalina on x86_64

Describe Bug

minifb supports a lot of platforms, including wasm:

• Windows
• MacOS X
• X11 (FreeBSD, Linux, *nix)
• Wayland (Linux) [there are some issues]
• iOS (beta)
• Android (beta)
• Web (WASM) (beta)

I noticed miniaudio does not specify supported platforms, which may be a better approach here?

Expected Behavior

I expect it to build for wasm platform.

Project Configuration

add_rules("mode.debug", "mode.release")
add_requires("minifb")
target("null0")
    set_kind("binary")
    add_files("host/src/*.c")
    add_packages("minifb")

Additional Information and Error Logs

I am still getting the same error:

Try xrepo update-repo

[konsumer]

That seemed to update things, but did not install:

The default find emsdk detection based on source . /emsdk_env.sh after setting the EMSDK environment variable, currently the brew emsdk is not supported.

It is recommended to try the official emsdk installation first.

./emsdk install latest
./emsdk activate latest
source ./emsdk_env.sh

Hmm, I wonder if it might be better to detect using emcc in path? As you can see in output above, I have it installed. Also, a fresh project works fine like this. If I add minifb, it fails.

Additionally, I performed same test on linux box, with emscripten installed from SDK (from git) and got same results. It builds emscripten programs fine, as long as I leave out minifb. WIth it in, it warned it wasn't supported, but seemed to install & use it on build.

I uninstalled brew emscripten, and installed from git, and it seems to work ok:

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false
