Subject: [PATCH 2/2] edid-decode: add build rule for emscripten output
Date: Sun,  9 Feb 2020 12:49:37 -0500	[thread overview]
Message-ID: <20200209174937.22844-3-imirkin@alum.mit.edu> (raw)
In-Reply-To: <20200209174937.22844-1-imirkin@alum.mit.edu>

All I can really say is that this works in my current setup. This
current setup was not the first setup I tried, with lots of random
flailing around emscripten and binaryen versions to be compatible with
my LLVM version. Perhaps later emscripten needs slightly different flags
to export functions, who knows.
