pure virtual method called about computelibrary HOT 7 CLOSED

Hi,
Unfortunately I don't have a Raspberry Pi to reproduce this issue.

A few things I would suggest you try:

1. Could you please try to run the binaries we provided here: https://github.com/ARM-software/ComputeLibrary/releases

2. Cross compile instead of building natively (In case it is a problem with the Raspberry Pi toolchain)

3. Try to run the example in GDB to see where it crashes.

We've successfully run this example on a variety of platforms so I'm curious to have more information about the issue you're seeing.

I only just noticed you were running Raspbian: isn't this OS compiled for armv6 ? (i.e no NEON support)

Have you tried using an armv7 hard float image instead ?
Should be faster too.

Hi @AnthonyARM ,
I found that it crashed in std::thread. And it can be solved by removing -march=armv7-a -mthumb in the compiler flags.
Details of my Raspbian:

uname -a
Linux raspberrypi 4.4.50-v7+ #970 SMP Mon Feb 20 19:18:29 GMT 2017 armv7l GNU/Linux

I really want to know what is armv7l and I didn't find it in the -march lists.

Maybe, it is a bug with the toolchain.

from computelibrary.

Yes, like mentioned above: raspbian is compiled for armv6 which is why it works when you remove armv7-a and thumb.

Could you try with a Linux armv7 OS ? ((Like Arch Linux or Ubuntu))

Hi @AnthonyARM ,
Thank you.
I will try Arch Linux and tell you the result later.

from computelibrary.

Yes, it worked on Arch Linux.

uname -a
Linux alarmpi 4.9.19-1-ARCH #1 SMP Thu Mar 30 19:23:11 MDT 2017 armv7l GNU/Linux

Cool, thanks for confirming.
Feel free to re-open the issue or create a new one if you run into more problems
