IE9 support about viz-js HOT 10 CLOSED

Assuming the absence of Int32Array is the only problem with running on IE 9, it might work to set Emscripten's USE_TYPED_ARRAYS setting to 0.

See "Emscripten Options" in the Emscripten tutorial: https://github.com/kripken/emscripten/wiki/Tutorial
Also, settings.js in Emscripten: https://github.com/kripken/emscripten/blob/master/src/settings.js

thanks for the suggestion, I'm attempting to try this however I'm having a hard time building viz.js, I get the following:

In file included from ./render.h:40:
./types.h:49:10: fatal error: 'cgraph.h' file not found
#include <cgraph.h>
         ^
1 error generated.
ERROR    emcc: compiler frontend failed to generate LLVM bitcode, halting
make: *** [graphviz-src/lib/common/libcommon-em.bc] Error 1

Any ideas what I have wrong?

It looks like the Makefile in master was mistakenly downloading Graphviz 2.30.1 rather than 2.28.0. (Further work is needed to support the newer version.) This is now fixed, but unfortunately I couldn't get the latest Emscripten to build a working Viz.js with the USE_TYPED_ARRAYS=0 setting. There may be some combination of options which allows this though, I'll have a look.

Thanks for your efforts, depending on the impact on performance it might not work well anyway. I can look at generating the svg on the server side for IE9 instead perhaps.

Yes, it might be better to do that. Also note that Viz.js isn't entirely reliable -- one of the examples in examples.html fails for me intermittently. It works most of the time, but I wouldn't claim it can be trusted as far as using Graphviz on the server.

Thanks for your awesome work. I have something working quite well with ie10 but I am stuck with ie8 within the organisation I work for at the moment. Would it be impossible to make this work with ie8? Any thoughts would be appreciated.

I am not able to run VIz.js using java 6 scripting engine oer Rhino.I am getting following exception

Any clues?

Any one got it running for IE 9 ? If so , then please share the viz.js for this.

Yes, emscriptem typed arrays support seems to be broken in newer versions, I meant to trace which version broke it but never got around to it... and it seems that nobody cares as only prehistoric browsers have this problem. I did manage to build a version which worked quite well on ie9 but that was against graphviz 2.28, so there's no home for that viz.js now as I see its now being built against 2.3x
