RE: [qemu-hexagon] Error mapping file: Invalid argument
Thanks for pointing me to the toolchain. I'll give it a try to see how it works. However, I'm more interested in being able to use qemu-hexagon as shown in my example below (QuRT). Is it possible? What kind of modifications qemu would require to make it happen?

In order to build Linux userspace binaries, you can use the toolchain in the QEMU container or this one https://github.com/quic/toolchain_for_hexagon/releases/tag/v2021.09.10 -Brian
[qemu-hexagon] Error mapping file: Invalid argument
Hello,
I’m trying to run Hexagon executables in qemu-hexagon. I’m using official
stable version v6.1. Here’s my rather simple program:
➜ ~ cat test.c
#include
int main()
{ printf("Hello Hexagon!");
return 0;
}
I’m using Hexagon SDK 4.0.2 toolchain:
➜ ~ ~/tools/Hexagon4/tools/HEXAGON_Tools/8.4.09/Tools/bin/hexagon-clang -mv67
-o test test.c
Running in qemu produces error somewhere in mmap
➜ ~ qemu-hexagon ./test
qemu-hexagon: ./test: Error mapping file: Invalid argument
Am I doing something naively wrong here?
Here’s are the some details about the executable
➜ ~ ~/tools/Hexagon4/tools/HEXAGON_Tools/8.4.09/Tools/bin/hexagon-llvm-readelf
-h ./test

Could you tell me where the problem is? Is it because I’m compiling for QuRT,
and qemu uses is linux-user? Or is something else?
