develonepi3Hello All, Trying to update (icestorm c49586 nextpnr 4419c3 yosys d6d5c2) icestorm built ok when trying to build nextpr "cmake -DARCH=ice40 ." -- Using iCE40 chipdb: /home/devel/nextpnr/ice40/chipdb -- Configuring incomplete, errors occurred! Does anyone know what is the fix?18:33

develonepi3tnt: I did a clone of my repo and the added upstream and fetch then merge. Is this not the correct steps?20:02
tntthere are submodules now. They need to be checked out.   git submodule init && git submodule update20:04
develonepi3tnt: in which repo icestorm or nextpnr or both?20:05
tntnextpnr20:10
develonepi3tnt Thanks!20:10

mwkdevelonepi3: congrats you found a bug21:42
mwknow let's figure out what exactly is going on here21:42
develonepi3mwk: this is line 758 log_assert(ifdef_already_satisfied);21:43
mwkI figured21:43
mwk... why does this code even work21:54
mwkhilarious21:55
mwkI found an unrelated bug in this area of code, but still see no way to trigger that assert21:56
mwkdevelonepi3: what code does this trigger on?22:05
*** chipb_ is now known as chipb22:22
develonepi3mwk: This is https://github.com/develone/catzip.git which was created from a version of icozip.  catzip connect to a parallel RPi3. It has sdram instead of sram.22:24
develonepi3I was trying to create a blif & json file.22:25
develonepi3I use zipcpu & autofpga to create the toplevl.v & main.v22:27
develonepi3mwk will the simple.log help. I can push to gist if you want.22:29
develonepi3mwk: It was very early Parsing `main.v' using frontend `verilog' following toplevel.v22:31
develonepi3mwk: The version of yosys is 03/24/21.22:36
develonepi3mwk: Yosys shows 3 updates since my version. Would these be the fix.22:42
mwk... well that's a very simple reproducer23:00
mwkdevelonepi3: thanks for the report, it'll be taken care of23:01
mwkhttps://github.com/YosysHQ/yosys/issues/271123:02
mwk... oh gods how is this code this dumb23:04
