File access errors in web version using Emscripten 2.0.25

[tech234a]

Hi!

I can't seem to compile a functional version of Boxedwine for Emscripten... every time I try and launch it I get a bunch of file access errors ultimately leading to Javascript exception in console.

I've tried compiling the Emscripten version of this project using Emscripten 2.0.26 and 2.0.25 (in case #27 was the cause of my issue, compiling with the lower version gave me different error messages but still failed to initialize).

Console output from the 2.0.25 build:

Unable to delete:/lib/wine/wineboot.exe.so error:Error: ENOENT: No such file or directory., '/lib/wine/wineboot.exe.so'
creating: root/base/opt/wine/lib/libwine.so.1.link
FATAL ERROR: Error: FS error
FATAL ERROR: Error: EEXIST: File exists., '/'
FATAL ERROR: Error: Error: EEXIST: File exists., '/'

I've been trying to launch Boxedwine HTML using an instance hosted on a local HTTP server using http://localhost:8000/boxedwine.html?root=debian10.zip&overlay=Wine-5.0.zip.

What am I doing wrong?

The issue appears to be with the overlays feature, combining the overlays into a single ZIP filesystem seems to solve the problem as described in #25 (comment). I'll keep this issue open for now just to ensure that my understanding that the overlay feature is broken is correct.

Hi,
Good to hear you were able to combine the debian + wine files together and it worked.
Previously they were published as a merged filesystem, since then the desktop version has matured greatly.

The overlay feature is designed for replacing WINE DLLs, adding fonts, game saves etc. That works fine in my testing.
