@cpaolini , it looks like this is an issue with GTest rather than libserial... I cannot reproduce the error on Ubuntu 19.10 with GTest 1.8.1 but your reporting did alert me to the fact that Gtest has jumped from 1.8.1 to 1.10.0, and v1.10 is not immediately compatible.

I will put some work into updating the unit tests to use GTest 1.10.0, but it might take some time. I'll report back as I make progress.

In the meantime, here is a WIP branch you are free to work from as well: https://github.com/crayzeewulf/libserial/tree/gtest_update

I'll keep everyone posted with any updates.

Thank you. I switched to the gtest_update branch, but am now having a missing declaration issue with nullptr in gtest-port.h:

[paolini@kon libserial]$ ./compile.sh
