There was significant discussion about the copyrights after NVIDIA acquired PGI, there are legal and IP issues involved. I'll forward your message up the chain here. -mw

All Rights Reserved. Copyright 2000-2013, STMicroelectronics, Inc. All Rights Reserved. to pgcc 13.8-0 64-bit target on x86-64 Linux -tp penryn Copyright (c) 2013, NVIDIA CORPORATION. All rights reserved. Unfortunately, if pgcc/pgCC/pgf* is used via a wrapper, for example as a MPI compiler wrapper, your change breaks autotools-based shared builds. This is due to the following case statement in libtool's 'libltdl/m4/libtool.m4': case `$CC -V 2>&1 | sed 5q` in ... *Portland\ Group*) lt_prog_compiler_wl='-Wl,' lt_prog_compiler_pic='-fpic' lt_prog_compiler_static='-Bstatic' ;; ... Providing a libtool patch to handle 'NVIDIA CORPORATION' in this case statement is easy (attached but untested). What isn't easy is to get a patch into a libtool release and to get this release to the users. This basically means that pgcc/pgCC/pgf* version >= 13.8 can not be used for autotools-based shared MPI builds any longer. This affects e.g., Score-P and Scalasca. I don't know about your copyright notice policy at NVIDIA, but you would help users if you would mention the previous copyright holders in 'pgcc -V' as well, e.g., $ pgcc -V pgcc 13.8-0 64-bit target on Linux -tp penryn Copyright (c) 1989-2000, The Portland Group, Inc.
