FATAL error : Simulation process did not launch #1906

Closed j-stephan closed 5 years ago

j-stephan commented 5 years ago

I am seemingly unable to launch any program in hw_emu mode. It doesn't matter which program I try to use, even the SDAccel examples fail. The error message is always the same (full verbosity enabled in sdaccel.ini):

FATAL ERROR : Simulation process did not launch
XRT build version: 2.3.0
Build hash: b8c74d3c679d82c13d8ae1b444891c485b68b52a
Build date: 2019-08-27 17:33:00
Git branch: master
PID: 3250
terminate called without an active exception
UID: 1000

I tested this with the master branch and the 2019.2 branch, both are showing the same behaviour. I can't test the older branches because they are missing patches for the current kernel in Ubuntu 19.04 (5.0.0-25-generic).

I'm using SDAccel 2019.1 and the Alveo U200 shell (xilinx_u200_xdma_201830_2).

A quick Google search shows that this is a rather new phenomenon and that even Xilinx employees are affected:

I'd be thankful for any pointers on how to further debug this issue since a quick glance at the source code didn't reveal anything obvious.

The solution was just posted in the thread linked above: My system was missing the csh shell. After installing it, hw_emu works.
