Scons TypeError #28

Closed mabruzzo closed 2 years ago

mabruzzo commented 4 years ago

While building enzo-e on stampede2, I encountered a python error related to scons at the end of the build process. Everything proceeds as normal until the very end of the build process. Right after the newly-built executable is copied to bin/enzo-p, the traceback for a python TypeError is output. However then the build script indicates that the installation succeeds.

This occurs for both choices of compilers. As far as I can tell, this doesn't actually cause any issues and the executable works as it is supposed to. However, I wanted to document this issue.

An excerpt of the output illustrating this issue is provided below. The full log from the same build process can be found here.

This could be due to an older version of python being used. Is the python2 module loaded?

mabruzzo commented 4 years ago

The problem seems to be independent of the python version loaded. I have tried the installation using:

Regardless of which installation I use, I get the same error

It would be useful if someone could verify if this is still an issue. PR #46 may have fixed this.
