fedora 31 error with arachne-pnr #3

Closed oystercatcher closed 3 years ago

oystercatcher commented 5 years ago

I have been testing icozip with fedora 31 , fedora 30 and rpi buster. This error appears on fedora 31 but not fedora 30.
Not sure if this has anything to do with icozip but asking for advice.

2.46. Executing BLIF backend.

The design should build with nextpnr, not arachnepnr. arachnepnr is no longer maintained, whereas nextpnr gets better performance. The fact that the makefile's are still using arachnepnr is a bug that needs to be fixed.

ok   thanks. I didn't have  nextpnr on the system when I ran make, so that explains the problem.     Fedora doesn't package  nextpnr  quite yet.I have been trying to build zipcpu  using just theprebuilt packages  as it will be much easier todocument the process for other users. I will give  nextpnr  from git a try. On Wednesday, November 27, 2019, 7:05:40 PM PST, Dan Gisselquist notifications@github.com wrote:

This was fixed in 8b7a4a65, and should've been closed long ago.
