開発環境を作る - Windows Subsystem for Linux を試す再び (5) -



This seems to be a problem with the crosstool-NG project. They have changed their download servers for more recent versions, which the script can't handle.
A quick fix that worked for me: Edit file /crosstool-NG/scripts/build/companion_libs/, change the following lines (starting at line 15):

do_mpc_get() {
    CT_GetFile "mpc-${CT_MPC_VERSION}" .tar.gz      \
        {http,ftp,https}://      \


do_mpc_get() {
    CT_GetFile "mpc-${CT_MPC_VERSION}" .tar.gz      \

crosstool-ng build error - wrong link to MPC tarball ?
