Summary0031668: Visualization - WebGL sample doesn't work on Emscripten 1.39
DescriptionBuilding WebGL sample using latest Emscripten release 1.39 switched from fastcomp to upstream (LLVM) toolchain results in numerous errors and non-working input.

First blocking error:
Uncaught (in promise) DOMException: Document.querySelector: '0' is not a valid selector occt-webgl-sample.js:9416


next error specific to eglSetSwapInterval():
emscripten_set_main_loop_timing: Cannot set timing mode for main loop since a main loop does not exist! Call emscripten_set_main_loop first to set one up.


another one related to eglGetProcAddress() for functions required by OpenGL ES 3.0 specs:
TKOpenGl | Type: Error | ID: 0 | Severity: High | Message:
  Error! OpenGL context reports version 3.0 but does not export required functions for 3.0 (glMapBufferRange)
Please report this issue to OpenGL driver vendor 'mozilla'


TagsNo tags attached.
Test case numberNot required

Committer: bugmaster Details Diff		 0031668: Visualization - WebGL sample doesn't work on Emscripten 1.39

OpenGl_Context now skips loading functions related to mapping buffer,
which are required by OpenGL ES 3.0 specs but not provided by WebGL 2.0.
Message_PrinterSystemLog does not use a broken emscripten_log() anymore, which corrupted UNICODE strings.

WasmOcctView::initWindow() - callbacks now set using EMSCRIPTEN_EVENT_TARGET_WINDOW
instead of 0 used by older Emscripten API.

Mouse callbacks now track canvas element and use
EmscriptenMouseEvent::targetX/targetY instead of ::canvasX/canvasY
as the latter was broken.

Added emscripten_set_main_loop() setup to shut up eglSwapInterval() error message.
Fixed missing \0 at the end of string converted by toUtf8Array().		 Affected Issues
