Hi,

I am building Catalyst on Linux x86\_64 with gcc 6.3.1. The build fails at the very end, while building pvserver, pvpython, pvbatch and pvdataserver. The error is ‘cannot find openpty’, see attachment. In case that it is relevant, I use a custom build of python-2.7.16, because the system python is 2.6.

Could you advise how to resolve this issue, please?  
Thanks,  
Ted

I figured it out. Linking with -lutil fixed the issue.  
Thanks,
