Compiling for Android

[kb1]

Egon,
In my OpenCPN root directory there's a file called VERSION.cmake.

This contains:
SET(VERSION_MAJOR "4")
SET(VERSION_MINOR "5")
SET(VERSION_PATCH "0")
SET(VERSION_DATE "2016-07-19")

When I used the wxqt branch it had:
SET(VERSION_MAJOR "3")
SET(VERSION_MINOR "3")
SET(VERSION_PATCH "2118")
SET(VERSION_DATE "2014-09-18")

Let me know what you find
Keith

Just hit your problem with the plugins!
commented out the hard coded stuff - building libopencpn.so comes later
and presumably so does:
${NDK_Base}/sources/cxx-stl/gnu-libstdc++/4.8/libs/armeabi-v7a/libgnustl_shared.so

Can you simply comment the add_directory line in CMakeLists.txt to build without plugins first?

Did you build with success using wxqt on linux? You also might be interested in my latest work on wxqt:

https://github.com/wxWidgets/wxWidgets/pull/319

which should also improve things and afaik dave hasn't pulled yet.

Hi boat_alexandra,
Are you seandepagnier?

Finally got it compiled and almost working!
Been too busy to look at your wxqt mods.

But I now have a SIGSEGV crash

In chart1.cpp at about line 2076
gFrame->Show( TRUE );

seems to cause this crash (from logcat):
F/libc ( 5832): Fatal signal 11 (SIGSEGV), code 2, fault addr 0xa27d2fe0 in tid 5859 (Thread-529)

I configured wxqt --with-opengl
I think that the fault is due to the qt version of toplevel.cpp being used in the build.
wxTopLevelWindowQt::Show doesn't exist! (Not very much seems to exist!)
But it exists in the gtk and gtk1 versions

So I commented out line 2076, but then got another similar crash.
Probably from another missing function.

Any ideas?
What config should I be using? OpenCPN seems to need --with-opengl.
How does toplevel.cpp get into the make?
I tried changing the qt version, but it didn't re-compile when I ran make.

Regards,
Keith
