I have just installed QFlow and its components from source and have run into a problem when following the tutorial (http://opencircuitdesign.com/qflow/ <http://opencircuitdesign.com/qflow/>).
The 'synthesise' stage ran fine, but the ‘place’ stage failed with a parsing error:
$ qflow synthesize place route map9v3

TimberWolfSC terminated abnormally with 1 error[s] and 0 warning[s]
Here’s some relevant parts of my machine configuration:
- QFlow 1.1 (7b65beec4100b60e23245cfbbe18ac8f8fc82fe3)
- Graywolf 0.1.4 (84a6e326b8ece3e0e9663aa6008c3ff9ac5ae4ce)
- Ubuntu 16.04.4 LTS
- gcc 5.4.0
- lex 2.6.0
- bison 3.0.4
This looks like it might be a bug with Graywolf, but I would be interested if anyone has any suggestions if there may be another way to resolve it.
Thanks in advance.
