| Hello Guys,
|
|
|
| I am using ArchLinux and I have been using OpenROAD from an install package from the AUR.
|
| This install does not seem to work anymore (it was working on my setup a couple of weeks ago).
|
|
|
| So I am trying to build from sources but I get the same errors as I get with the AUR package:
|
| ```

|
| Seems to be something related to Swig with TCL. Does anybody know what the problem is?
|
|
|
| Thanks for your help

| ### maliberty |
| What version of TCL and swig do you have installed? |
|
|
| ### maliberty |
| Perhaps something is different in 4.2.1 as with 4.1.0 I don't see any used of Tcl_Size in tclSwig.h. Is it possible for you to downgrade? |
| |
| ### stefanottili |
| Does anybody know how to downgrade swig on MacOS M1 homebrew ?
|
| The current SWIG Version 4.2.1 causes the same error here.
|
| Can be worked around by commenting out the two offending lines, they seem to be in an error path ... |
