Thanks for trying the software and reporting the issue.
I succeeded to reproduce the problem, and I guess there are something wrong with bytestring-encoding package.

[msakai]

It was indeed the problem of bytestring-encoding and I uploaded the new version bytestring-encoding-0.1.1.0 to Hackage.
The problem will be fixed if you re-build toysolver using the new bytestring-encoding package.

Hi,
thank you for trying to fix it. Unfortunately new installation failed.

$>sudo apt install zlib1g-dev
$> cabal install toysolver
ok now

I've tested .lp works now but opb not.

./toyconvert Sudoku.lp -o Sudoku.opb
~/.cabal/bin$ ./toysolver --pb Sudoku.opb
toysolver: ParseError "endOfInput"

.toysat the same "endOfInput" error.

[msakai]

This is caused by an empty objective function min: ; which is not allowed in the OPB file grammar.
And I filed an issue msakai/pseudo-boolean#4 .

As a workaround, please remove the min: ; line from the Sudoku.opb file.

[msakai]

I released pseudo-boolean-0.1.10.0 which allow parsing min: ; (and other occurrences of empty <sum >expression) although it does not conform to the OPB file grammar define in http://www.cril.univ-artois.fr/PB11/format.pdf .

Hi Masahiro, very appreciate that you fixed that. I'm trying to evaluate different encodings of PB constraints into SAT. Would you be able to help with another issue with PYPBLIB? rjungbeck/pypblib#1 It's library in python but nobody is maintaining that project I guess and there should be all encodings available according to documentation. Thank you Best regards Vlasta st 12. 5. 2021 v 2:21 odesílatel Masahiro Sakai ***@***.***> napsal:
