Linker and build errors on Android

[Slick]

I was able to build some libraries for Android but had to build for double precision to avoid build errors. I don't want or need double precision.

Could this be causing link errors to my app that just uses floats and not doubles? I can't work out yet why I have linker errors.

[Slick]

I am trying to just make it simple and not use double precision. So I removed -D_NEWTON_USE_DOUBLE and went back to just build Newton with floats.

Line 413 of dgVectorScalar.h:

Code: Select all

DG_INLINE dgVector ShiftRight() const
   {
      return dgBigVector (m_w, m_x, m_y, m_z);
   }

Why is this returning a dgBigVector. I am not using -D_NEWTON_USE_DOUBLE and am using -DDG_SCALAR_VECTOR_CLASS.

This is the actual error that I am getting:

Code: Select all

In file included from ../sdk/dgCore/dgMatrix.cpp:23:
In file included from ../sdk/dgCore/./dgMatrix.h:28:
In file included from ../sdk/dgCore/./dgVector.h:33:

                       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I just noticed that there was a commit for this last month after I updated from GIT.

I was going to make the change in my code and test but it looks like it was fixed.

Onward and let's see what is next.

Hi Slick,

In the project options menu you can see a proc flag about NEON but it is not use with this project.
In the project the DG_USE_THREAD_EMULATION flag is define enabled.

Great thanks for the help. I did get something built yesterday but was having problems getting the debugger to work. Finally I worked it out and found that I am hitting an assert in resettimer. Hopefully it is just a define issue. I'll try and look today and also will look at your links.

Updated Android Newton Projects VS_2017:

I have fix many things.
I have fix the projects options for 32bits & 64bits and I have enable the multithreads.
I don't use the neon version because the demo is build with the 32bits version for my old android device.
The 32bits libs & demo build working good on 32bits and 64bits devices.
The project is ready to use with 64bits version for enable the neon mode on a 64bits demo project.
I have fix the demo scene refresh too, If you open a other app over the demo and if you back to the demo it don't crash and it is correctly updated.
You can find more informations in the help.txt file in the zip.
