To reproduce

For MacOS:

brew update
brew install boost
cd bitcoin
./contrib/install_db4.sh $(pwd)
export BDB_PREFIX=$(pwd)/db4
./autogen.sh
./configure BDB_LIBS="-L${BDB_PREFIX}/lib -ldb_cxx-4.8" BDB_CFLAGS="-I${BDB_PREFIX}/include" --enable-cxx --without-gui --disable-tests --disable-bench
make

For Alpine see: Dockerfile, build log.

System information

Tested for v0.19.0.1 & e6f167bfd .

Reproducible on MacOS/amd64 as well as debian/arm, and ubuntu/amd64.

Speculation

It seems to be caused by a change in boost described as (src):

• Deprecated: The following members of recursive_directory_iterator are now marked as deprecated: level(), no_push_pending(), no_push_request(), no_push(). Users are advised to replace their use with the standard counterparts: depth(), recursion_pending(), disable_recursion_pending(). Note that recursion_pending() has the opposite meaning compared to no_push_pending() and no_push_request(). Deprecated methods will be removed in a future release.
