I don't know if there is such a list, but I'd be glad to add several externals I've been able to compile with my machine, and comment about how it has been done, then pdx maintainers could had them to the build farm. The problem is that most pdx externals building use a single Makefile for compilation that resides in externals, so it makes tricky patch submiting, because it's a lot easier to use the Makefile provided by the dev in most cases (that's happening with unauthorized externals for example). I sometimes submit dll's to the list, but it's not really a good thing. if one is interested I've built these ones lately: exciter filterbank formant pianoroll probalizer samplebox sonogram speex spigot~ most just need -liberty in linker flags -- Patrice Colet ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

(a) Awesome! Would you mind telling us more about your project? it was just to test out libpd embed in a C++ application. by using Gem i was almost sure it was the most complicated external to run. to make it work, i had to compiled my program with: /-Wl,–export-dynamic -Wl,–whole-archive ./libpd.a -Wl,–no-whole-archive/ there's a small GUI example here (end of the page): http://www.workinprogress.ca/libpd/ (b) Every once in a while I find myself tempted to port Gem to Android, but then I wonder whether this would actually make sense. Essentially, the way I see it, Gem maps a subset of OpenGL into Pd and controls graphics with Pd messages. With libpd, you can use OpenGL directly in your client code and still exchange messages with Pd, and chances are that it'll be easier to do the math for OpenGL outside of Pd. Any thoughts? like matju said, Gem is more than just OpenGL, so i like the fact that i don't need to know OpenGL to make simple stuff (even some basic GUI) :) Peter thanks again for libpd! ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

A slightly longer answer is that your operating system determines how externals work. If dlopen is available (e.g., on Android), then you can load externals as needed, the way Pd does it. If dlopen is not available (e.g., on iOS), then you need to decide in advance which externals you want to use and compile them into your code.
