I managed to get my application to build using emscripten 1.21.0 and the
following steps
* Copy system/lib/libSDL2.a from your fork of Emscripten to my
project's "other_lib" area
* Add -lSDL to AdditonalDependencies
* Add <path to my other_lib area> to AdditionalLibraryDirectories
However nothing is being drawn and no error messages output. The only
output in the console is echoing of the GETs for the .html, .js and
.data files and "pre-main prep time: 45 ms". I will now debug it.
The difference from last week is that I was using emscripten 1.16.0
then. I had changed EMSCRIPTEN_ROOT in ~/.emscripten to my clone of your
fork but had failed to change EMSCRIPTEN in my global environment, which
is what vs-tool uses to select emcc.
