<html><body><p><font size="2">Hi Siegmar,</font><br><br><font size="2">The trunk is currently missing the nvptx runtime, so even if you enable OPENMP_ENABLE_LIBOMPTARGET you only build the base library, the CUDA plugin and the generic-elf-64 plugin. The nvptx runtime contains CUDA versions of runtime functions and is necessary for proper execution on the device.</font><br><br><font size="2">We are currently working on upstreaming the nvptx runtime, I expect to have something ready by the end of next week.</font><br><br><br><font size="2">George</font><br><br><img width="16" height="16" src="cid:1__=0ABB0B58DFF178DE8f9e8a93df938690918c0AB@" border="0" alt="Inactive hide details for Siegmar Gross via Openmp-dev ---01/11/2017 13:21:03---Hi, today I've built the latest version of llvm"><font size="2" color="#424282">Siegmar Gross via Openmp-dev ---01/11/2017 13:21:03---Hi, today I've built the latest version of llvm-trunk.
