libprotobuf.a : error adding symbols : Files in wrong format

[Scriabing]

After insmoding opendla.ko correctly , I compile umd by using command as follow. root@xilinx-zcu102-2018_3:/media/umd# make TOOLCHAIN_PREFIX=/usr/bin

when i readelf sw/umd/core/src/compiler/libprotobuf.a ,the file is related with x86. However, I use Xilinx's board named zcu102 with a53.

I compile protobuf-2.5.0 source code with this board's cross compiler named aarch64-linux-gnu-gcc . But a header file named platform_macro.h in source code reports that Host architecture was not detected as supported by protobuf.

which version of protobuf should I choose? How to get libprotobuf based on arm64? Is this file related with board?

When you look at your error, you are able to see that the error occurred while you were trying to build the compiler

The compiler is supposed to be executed at a desktop machine with a x86 or x86_64 processor inside. This means you need to compile it for x86 not for arm64

Hello, i have the same issue, did you fix it? @MaxS1996 so what is yur suggestion, to make a cross-compiler form the PC ?

Hi @AndiNNT, It has been some time since I worked with this, but just do not build the compiler for ARM and you should be fine.

I cannot remember how to only build the other components, but it should be possible.

The Compiler itself is also quite limited, it only supports Caffe as input format, which is outdated and is limited in the supported networks.
