[Ovmsdev] Scripting: Duktape update to version 2.5.0

[Craig Leres]

Hum... I haven't tried to build for a week or so and am now getting a 
error from the new duktape:

     ice 840 % gmake
     Toolchain path: /home/ice/u0/leres/bin/xtensa-esp32-elf-gcc
     Toolchain version: crosstool-ng-1.22.0-80-g6c4433a5

     gmake: *** [/home/ice/u0/leres/esp/esp-idf/make/project.mk:552: 
component-duktape-build] Error 2

I looked at the code and don't see the problem:

                 /* XXX: native funcptr could come out of call setup. */
                 if (func) {
                         rc = ((duk_hnatfunc *) func)->func(thr); // 2268
                 } else {
                         duk_tval *tv_func;

My guess is my toolchain is too old? I'm using 1.22.0-80-g6c4433a5. 
Looking here:

     https://github.com/espressif/crosstool-NG

Should I switch to the esp-1.23.x branch? Or am I just SOL because 
you're all using a binary release toolchain and espressif hasn't 
released the source to the crosstool-NG they're using to build it?
