Compiling fails after update on Ubuntu 18.04 with in-kernel driver. "make sdk_install_pkg" gives the following error: ipp/ipp_disp/ippcpsgx_disp00389.c:53:18: error: conflicting types for ‘sgx_disp_ippsECCPSignSM2’

Full output is attached. SDK and PSW were successfully built on this machine before, so the error is due to an update. out.txt

Seems you forgot to download the prebuilt packages for latest release. So the header file 'ippcp.h' in your repo is old and not compatible with latest code. Please run "make preparation" to refresh the prebuilt packages before build SGX. To avoid other potential issues, suggest to make your code repo clean before build.

This fixed it, though I had to delete my existing local repository and repull.
