The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this up by moving the related file to use "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/memory-model` Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATH Signed-off-by: Tiezhu Yang <yangtiezhu@xxxxxxxxxxx> --- tools/memory-model/scripts/checkghlitmus.sh | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tools/memory-model/scripts/checkghlitmus.sh b/tools/memory-model/scripts/checkghlitmus.sh index 6589fbb..f72816a 100755 --- a/tools/memory-model/scripts/checkghlitmus.sh +++ b/tools/memory-model/scripts/checkghlitmus.sh @@ -35,13 +35,13 @@ fi # Create a list of the C-language litmus tests previously run.
