Re: [gem5-users] execution problem hello.c in architecture armv8 big.LITTLE
Sorry, those images are undocumented and I don't know how they are generated + parsec is highly unmaintained and not made with cross compilation in mind. The best advice I can give at the moment is: use my setup: https://github.com/cirosantilli/linux-kernel-module-cheat/tree/16de55dd2f89ae44c1ee0fee1c39d23ee2b36b13#parsec-benchmark which I understand and have clearly documented what works and what does not. In the future I might try to understand the state of the current images and contribute better ones / documentation.

Re: [gem5-users] execution problem hello.c in architecture armv8 big.LITTLE
Hi, The important line is this one: / tmp / script: line 3: cd: / home / root / parsec: No such file or directory No way you can get the binary running if you cannot cd to the directory where the binary is located. That has no relation with how the binary was compiled. My intuition is that the directory is in fact "/root/parsec". It's just a guess based on the absence of home directory for root user in my Ubuntu (although I don't know which image you're using). To be sure just add an ls to show the directory at each point like this: PARSEC_DIR = "/ home / root / parsec" ls cd /home/ ls cd root ls cd parse ls On 01/06/18 08:45, Ciro Santilli wrote: This is not required, the best thing to do is to find what is the proper compatible cross compiler for the image: https://stackoverflow.com/questions/31929092/trying-to-run-a-cross-compiled-executable-on-target-device-fails-with-no-such-f/49993116#49993116 On Fri, Jun 1, 2018 at 6:34 AM, Tung Hoang wrote: You may need “-static” for arm cross-compiling. /T On Thu, May 31, 2018 at 3:19 PM commerce _com wrote: Hi ciro, I'm sure the binary of the compilation is in the image on the path: / home / root / parsec but I did not understand how to solve this problem; Please. com_. 2018-05-31 23:02 GMT+02:00 Ciro Santilli : Likely incompatible compiler using wrong dynamic loader, do "file hello", see "interpreter /some/path", and check if "/some/path" is present on guest.
