OpenCPN on Raspberry Pi2

@JM...

Sounds like it is blowing up on out-of-memory situation.

Try this..

Reduce the allocated GPU texture size in OCPN config file.

GPUTextureMemSize=64

Try smaller numbers, like 64 or 32.

Good Luck
Dave

Tried 32, no difference.

Try single chart mode (F9).

Same SIGKILL.

I am using WxWidgets 3.0.0 on this system, I was not able to get 3.0.2 to build. Could that be a problem? What version are you using?

No problems in other modes, just OpenGL=on, caching=off, RNC charts.
It's not really a mode I would use, but should work.

Cheers,
JM.

Faced with your issue, I would try ddd, run the simplest configuration until a crash, and look at the backtrace.

I can do that, but isn't ddd just a frontend for GDB?

I already tried GDB.

What am I missing here?

Thanks,
JM.

Does gdb break cleanly on a crash (SIGKILL)? What does a backtrace look like at that point?

See post #86 this thread.

No backtrace is available.

I'm not sure how to debug it.

Hi Sean,

I see you have pushed a lot of fixes for ARM Linux.

Are all your fixes in now ? Let me know and I'll give it a try.

Thanks,
JM.

I still think it is a memory problem.

Please edit glTexCache.cpp, Line 1322, and enable OCPN memory inventory printf reports.

#if 1
    if((m_ticks % 4/*120*/) == 0){
    
    // inventory
    int mem_total, mem_used;
    GetMemoryStatus(&mem_total, &mem_used);
    
    size_t map_size = 0;
    size_t comp_size = 0;
    size_t compcomp_size = 0;
    for(int i=0 ; i < m_ntex ; i++){
        glTextureDescriptor *ptd = m_td_array[i];
        if(ptd){
            map_size += ptd->GetMapArrayAlloc();
            comp_size += ptd->GetCompArrayAlloc();
            compcomp_size += ptd->GetCompCompArrayAlloc();
        }
    }

    size_t m1 = 1024 * 1024;
    printf("%6d %6ld Map: %6d  Comp:%6d  CompComp: %10d  %s\n", mem_used/1024, g_tex_mem_used/m1, map_size/m1, comp_size/m1, compcomp_size, m_ChartPath.mb_str().data());
  
///    qDebug() << "inv" << map_size/m1 << comp_size/m1 << compcomp_size/m1 << g_tex_mem_used/m1 << mem_used/1024;
    }
#endif

Build, and run the app from a cli box, so that the printf is visible. Lets see what happens here.

@JM....

Sean's fix for the blurring on GLES is in master now. Looking forward to your test report.

He has a branch with changes to glChartCanvas:rawQuiting()
Removing glPolygonStipple because it is not supported in GLes.

It has not been included yet ? Maybe abandoned ?

Cheers,
JM.

I'm not sure what's so funny about DrawQuitting ?

Cheers,
JM.

@JM...

Yes, hilarious....

Patch is maybe abandoned. I don't recall seeing this as a Pull Request. Does it have any effect on your GLES system if this code is in or out?
