Thanks, but that did not fix it.

It seems to be crashing before the patch you suggested:

Re: OpenCPN Beta test 4.1.602 Release

The Latest OpenCPN from Git crashes in a different way on my ARM system.

Every time I apply changes or click ok in the config menu I get this error:

(gdb)

Further to the new bug: It only happens if no plugins are enabled and I do not enable at least one before closing the config.

Also, the chart selector toolbar is working again !!!

Cheers,
JM.

Good catch, fixed in master now.

Thanks, that fixes it.

So, now I am left with one bug (well one main one at least):

To recap:

If I start OpenCPN with no config file it works correctly (for the most part).
I can configure charts, OpenGL, chart selector rendering is working...

When I shut it down and re-start it I get a Segmentation Fault.
Always at the same spot (see preceding post).
I dont even have to change any config for this to happen:
just delete config file, run opencpn, close without doing anything, run opencpn again and it crashes.

Any Ideas how to debug this ?

Thanks,
JM.

Re: OpenCPN Beta test 4.1.602 Release

JM...
First build a binary without optimizations:
Code:
cmake -DCMAKE_BUILD_TYPE=Debug ..
make
Then run it in gdb and see if the stack trace makes more sense.
If still not, you will probably have to step through the code until the offender is found...

Are the optimizations why I was seeing instructions repeated while stepping ?

Will try the debug build tonight.

Thanks,
JM.

Re: OpenCPN Beta test 4.1.602 Release

JM...
Might be - stepping through code which is -O3 optimized tends to sometimes be a total nightmare, to which extent depends on the code - it might have been completely changed by the compiler or it may be exactly the same as with -O0 and perfectly traceable.
Of course disabling the optimizations and having well debuggable executable comes at the price of it's performance.

The debug build seems to give the same result, unless I'm doing something wrong?

Ok, maybe the code needs to be injected somewhere that is hit earlier. Could you try sticking it somewhere like MyApp::OnInit() ?

Sorry, this is probably something simple, but I'm not sure what m_bsetup is for or how to fix this code:

Code:
libs gtk+-2.0` -o CMakeFiles/opencpn.dir/src/chart1.cpp.o -c /home/aruntu/OpenCPN/src/chart1.cpp
/home/aruntu/OpenCPN/src/chart1.cpp: In member function ‘virtual bool MyApp::OnInit()’:
/home/aruntu/OpenCPN/src/chart1.cpp:1152:10: error: ‘m_bsetup’ was not declared in this scope
     if( !m_bsetup ){
          ^
make[2]: *** [CMakeFiles/opencpn.dir/src/chart1.cpp.o] Error 1
make[2]: Leaving directory `/home/aruntu/OpenCPN/build'
make[1]: *** [CMakeFiles/opencpn.dir/all] Error 2
make[1]: Leaving directory `/home/aruntu/OpenCPN/build'
make: *** [all] Error 2
aruntu@aruntu:~/OpenCPN/build$

Re: OpenCPN Beta test 4.1.602 Release

I added it like this and it fixed the problem:

Code:
bool MyApp::OnInit()
{

    wxStopWatch sw;
    
    if( !wxApp::OnInit() ) return false;

+#if defined(__WXGTK__) && defined(ARMHF) && defined(ocpnUSE_GLES)
+    // There is a race condition between cairo which is used for text rendering
+    // by gtk and EGL which without the below code causes a bus error and the
+    // program aborts before startup
+    // this hack forces cairo to load right now by rendering some text
+ //   if( !m_bsetup ){
+        wxBitmap bmp( 10, 10, -1 );
+        wxMemoryDC dc;
+        dc.SelectObject( bmp );
+        dc.DrawText( _T("X"), 0, 0 );
+ //   }
+#endif
Should this be added to the master ?

I am also altering glChartCanvass.cpp to disable the stencil buffer every time I get a new version. based on this conversation with Dave:
OpenCPN Runs on Embedded ARM
That was to fix a problem with displaying certain features of ENCs. Perhaps that could be added by checking for MALI graphics ?

Thanks,
JM.

There seems to be something wrong with your compiling environment or OCPN sources. There is no "m_bsetup" in chart1.cpp but only in glChartCanvas.cpp and declared in glChartCanvas.h
You may use the grep command for searching?
