Hi guys, I've just created this repository on github: https://github.com/luismreis/node-openvg
I'm attempting to create bindings for OpenVG to get access to hardware acceleration. DirectFB seems slow at higher resolutions, and initial tests with SDL (using node-sdl) weren't very conclusive. I'm facing this problem: I can call broadcom's init function, but, as soon as I call the EGL (bindings between window system and OpenVG/Open GL ES) apis, I get stuck on an internal V8 function. The stack trace for my main thread is: #0 0x002a719c in v8::internal::JSReceiver::LocalLookup(v8::internal::String*, v8::internal::LookupResult*) () #1 0x002a7ce4 in v8::internal::JSReceiver::Lookup(v8::internal::String*, v8::internal::LookupResult*) () #2 0x003d9614 in v8::internal::LookupForRead(v8::internal::Handle<v8::internal::Object>, v8::internal::Handle<v8::internal::String>, v8::internal::LookupResult*) [clone .constprop.66] () #3 0x003db7ec in v8::internal::LoadIC::Load(v8::internal::InlineCacheState, v8::internal::Handle<v8::internal::Object>, v8::internal::Handle<v8::internal::String>) () #4 0x003dbe80 in v8::internal::LoadIC_Miss(v8::internal::Arguments, v8::internal::Isolate*) () #5 0x2d30a09c in ?? () #6 0x2d30a09c in ?? () The output of my hello.js app is: Waiting 4 seconds Calling init. Calling eglGetDisplay... eglGetDisplay returned: 0x00000001. vgInit done! openvg::Init done! If this didn't halt that output should be followed by something similar to: Got back from init. Waiting 3 seconds Waiting 2 seconds Waiting 1 seconds Calling finish. Got back from finish. "openvg::Init done!" is the last thing executed in my native code. So, my conclusion is that my code runs successfully but it somehow breaks something internal to V8/node. Notice that the waiting function (triggered by a setTimeout) also gets stuck. Broadcom's init function (bcm_host_init()) starts something like 4 or 5 threads related to processing remote control commands and multimedia functions, but, if it's the only thing executed the test script runs fine. Any hints ? Note 1: I'm trying to build node with debug support. With my standard configuration gdb breaks with "Illegal instruction" reading SSL related libraries before running anything. Note 2: This may be of interest to anyone implementing OpenGL ES bindings on the raspberry. I think the same sequence of going through EGL is also required.
