Running seq on WSL2
RenzoTale88 opened this issue · 4 comments
Hi,
I've installed seq using the command line specified on the website. However, when I run it I come across an Illegal instruction error:
~/.seq/bin/seqc --help
Illegal instruction
I've seen the issue #229 and I've checked the cpu info, which are as follow:
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 30
model name : Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz

address sizes : 36 bits physical, 48 bits virtual
power management:
The cpu is admittedly old, but it does support sse4.2. Is there any other reason why it should not work?
Thank you in advance for your help,
Andrea
Hi @RenzoTale88 — would it be possible to run seqc in gdb to see what instruction causes the issue (e.g. as described here)? Then we can fix it on our end in the next release.
@arshajii just tried it now. After running gdb, I get the following:

[New LWP 268]
Core was generated by `./seqc'.
Program terminated with signal SIGILL, Illegal instruction.
#0 0x7f53dfb9b609 in ?? ()
However, when running the memory layout it just tells me that it cannot access the memory at the address:
core LWP 282 In: L?? PC: 0x7f53dfb9b609
Cannot access memory at address 0x7f53dfb9b609
(gdb)
It also opens a split terminal showing the message [ No Assembly Available ].
Not sure can be of help.

FYI we think we know what's causing this, and should be fixed in the next release in a few days.
This should be fixed in 0.10.3 (released yesterday). Feel free to reopen if the issue persists.
