Also style-only commit applied. Pardon: could not reopen my previous PR #15966. ACKs for top commit: ryanofsky: utACK 59cb722fd050393a69f1e0df97d857c893d19d80. Changes since last review: adding a new commit which updates configure script to fall back to disabling upnp if version is too old, adding a requested comment explaining static_assert condition, and fixing a spelling (jessy/jessie) Tree-SHA512: 42ed11bc2fb2ec83d5dd58e2383da5444a24fd572707f6cf10b622cb8943e28adfcca4750d06801024c4472625b5ea9279516fbd9d2ccebc9bbaafe1d148e80d --- configure.ac | 23 ++++++++++++++++++++++- src/net.cpp | 48 +++++++++++++++++------------------------------- 2 files changed, 39 insertions(+), 32 deletions(-) diff --git a/configure.ac b/configure.ac index 859af2154f..d32c9bf195 100644 --- a/configure.ac +++ b/configure.ac @@ -967,6 +967,26 @@ if test x$use_upnp != xno; then [AC_CHECK_LIB([miniupnpc], [upnpDiscover], [MINIUPNPC_LIBS=-lminiupnpc], [have_miniupnpc=no])], [have_miniupnpc=no] ) +dnl The minimum supported miniUPnPc API version is set to 10.
