Convert the download_prerequisites script to use http instead of ftp. This works better with firewalls, proxies, and so on. It's also faster, a quick test on my system before patch:
time contrib/download_prerequisites --directory=/tmp/foo --force ... real 0m17,843s After patch: time contrib/download_prerequisites --directory=/tmp/foo --force ... real 0m11,059s (fastest of three runs) Question: Should we in fact use https? I haven't used it since download_prerequisites checks that the sha512/md5 matches the ones in the GCC tree, but maybe there are reasons? Even https is in fact faster than ftp: time contrib/download_prerequisites --directory=/tmp/foo --force ... real 0m12,729s --- contrib/download_prerequisites | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/contrib/download_prerequisites b/contrib/download_prerequisites index 72976c46c92..aa0356e6266 100755 --- a/contrib/download_prerequisites +++ b/contrib/download_prerequisites @@ -32,7 +32,7 @@ mpfr='mpfr-3.1.4.tar.bz2' mpc='mpc-1.0.3.tar.gz' isl='isl-0.18.tar.bz2' -base_url='ftp://gcc.gnu.org/pub/gcc/infrastructure/' +base_url='http://gcc.gnu.org/pub/gcc/infrastructure/' echo_archives() { echo "${gmp}" @@ -58,7 +58,7 @@ esac if type wget > /dev/null ; then fetch='wget' else - fetch='curl -LO -u anonymous:' + fetch='curl -LO' fi chksum_extension='sha512' directory='.' -- 2.17.1
