After updating the RHEL guest to 7.6 I tried to reinstall the guest additions but building the graphics driver module failed. So I tried with the test build 5.2.21 revision 126213 but building the graphics driver module failed, too. To reproduce this issue just try to install the guest additions in a RHEL 7.6 guest system. There is a topic to this issue at: https://forums.virtualbox.org/viewtopic.php?f=3&t=90103 I'm going to attach related log files to this case once it is open. If I could do anything else to track this down, please let me know. I'm not experienced in tracking down and debugging possible bugs in virtualbox, yet.",defect,closed,guest additions,VirtualBox 5.2.20,fixed,,,Linux,Linux
