# the configure line
./configure

make check

# Become root to install it

## Install it
# If you added --enable-shared above, run 'ldconfig' after 'make install'
# and check /usr/local/lib for old versions of libsigsegv.so.* if this
# is an upgrade.
make install

# Make sure your non-root user can remove the source later
chown -R $USER .
chmod -R u+w .

# Become yourself again
