Bug #125238 for DB_File: DB_File fails when building perl on macOS 10.13

DB_File fails when building perl on macOS 10.13 sse also https://rt.cpan.org/Public/Bug/Display.html?id=124836 * macOS 10.13 perl does include DB_File * ... but macOS 10.13 perl's DB_File is broken * building DB_File distribution with /usr/bin/perl fails * Hmmm, does DB_File.bundle tell us anything? * Let's make libdb work * Success with 5.22.4, 5.24.4, 5.26.0, 5.26.1, 5.26.2 & 5.27.11 I built perl-5.26.1 on macOS 10.11, apparently successfully. This was done a while ago and there's a slight possibility I tweaked the build process to make it "work". Anyway Dannys-MacBook-Pro:DB_File-1.841 dthomas$ /opt/uq.cis.work/build.perl/perl-bootstrap/perl-5.26.1/perl -e 'use DB_File; print "db_version=$DB_File::db_version\n"' db_version=1 Neither MacPorts or Homebrew is installed on this machine. And in any case I don't think either offer berkeley-db version 1. This is also the version reported by /usr/bin/perl Another person reporting this problem How to install Perl on macOS 10.13 High Sierra https://stackoverflow.com/questions/46660971/how-to-install-perl-on-macos-10-13-high-sierra They solved it by installing Homebrew's Berkeley DB and perl brew install berkeley-db perlbrew install perl-5.26.1 But I'm building a perl outside MacPorts/Homebrew There's a comment on this stackoverflow page It's probably worth reporting this on rt.perl.org. That 'mostly harmless' needs to be changed when libdb isn't installed! – RickMeasham Nov 22 '17 at 22:49 I think 'mostly harmless' can be true as using macOS' /usr/bin/perl to build DB_File-1.841.tar.gz on macOS 10.11 shows this message but builds and PASSes the tests. Mind you I don't know how libdb is resolved as I couldn't find it either on macOS 10.11 or macOS 10.13. The fact that perl and the distribution build on macOS 10.11, and report db_version of 1 strongly suggests libdb is visible to the linker. But the failure on macOS 10.13 indicates the mysterious libdb is no more. In that case there's no way to fix the distribution except by adding documentation, and perhaps emit a warning from Makefile.PL. People manually building perl on macOS 10.13 might not not notice or care about the test failure, but my build script dies on any backtick operation failing, i.e. backtick "make test" so I was made aware of the issue. Anyway here's my setup OS 10.13.3 /usr/bin/perl -V listed below XCode downloaded from app store, apparently "Version: 9.3 (9E145)" Command_Line_Tools_macOS_10.13_for_Xcode_9.3.dmg downloaded from https://developer.apple.com/download/more/ MacPorts installed.
