GetWorldPos error

[freakfs]

I'm very interested in your project. What's your current progress?

I ran your project and found the card in CV:: mat worldpos = points [i] - > getworldpos();

The console then prints the following error

RuntimeError: Aborted(segmentation fault)

Can you tell me something about the progress of debugging

Hi @freakfs glad you are interested!

The project will not do a lot just yet, besides print out the position of any tracked points.

In terms of my progress, there is still an unaligned memory access error I need to diagnose. However the main issue for the moment is that I am having some problems initialising the tracking on my device (even with custom camera parameters which I obtained with a calibration tool). Need to work on this but have had little time recently. Did you manage to get tracking started?

There's some info about Emscripten debugging here: https://emscripten.org/docs/porting/Debugging.html

[freakfs]

I try to run in debug mode. At present, I can output some information

However, running more times will cause the browser to get stuck, which may be related to "pthread"

Like this:

@nickw1 sorry i may have wasted your time
Can you provide the parameters of your EMCC instruction
For example, emcc xxx xxxx.a -I xxx?

I have linked many static libraries, but have been unable to debug. Now I can only debug after packaging

@freakfs did you build with the cmake file provided?

That includes all the options, libraries, etc.

emcmake cmake .
emmake make

That "blocking on the main thread" doesn't actually seem to cause any problems for me, at least not yet. It's using the pthread provision of Emscripten.

@nickw1
Yes.with
emcmake cmake . -DCMAKE_BUILD_TYPE=DEBUG emmake make -j

but Emmake again after each change
so i need the parameters of your EMCC instruction

@freakfs these are all detailed in the CMakeLists.txt, look for the add_compile_options() and add_link_options() lines.
