I'm not doing anything special, just the regular emscripten build instructions:

$ ./autogen.sh
$ emconfigure ./configure --prefix=/tmp --enable-fixed-point
$ emmake make

How do I check the targets?

The output from configure and make can be found here:


There is an archive download link on the right.

Again, properly fixing this is one thing, just creating a work-around
to at least get it to build is another. For example, just skipping the
tests altogether when building under emscripten. It's a minor
improvement over the status quo, but an improvement nonetheless. And
probably worthwile.

What do you think?

If I knew anything about autotools I'd submit a patch myself, but alas.
