Issue #19233 has been updated by mdalessio (Mike Dalessio). When sqlite3-ruby's (v1.5+) extconf calls `pkg_config()`, the argument `pkg` is "/opt/ruby/lib/ruby/gems/3.2.0+2/gems/sqlite3-1.5.4/ports/x86_64-linux-gnu/sqlite3/3.40.0/lib/pkgconfig/sqlite3.pc". In this docker container, `RbConfig::CONFIG["PKG_CONFIG"]` is set to `""`. Previously I believe that this method set the variable `pkgconfig` to "pkg-config". However, after 7f1ca66 it falls through the `if` conditions and is set to `nil`, causing this error. ---------------------------------------- Bug #19233: Failed to install sqlite3 gem since 7f1ca666424849134990d022266bcd4d6636465f using Docker https://bugs.ruby-lang.org/issues/19233#change-100639 * Author: yahonda (Yasuo Honda) * Status: Open * Priority: Normal * ruby -v: ruby 3.2.0dev (2022-10-02T06:19:14Z :detached: 7f1ca66642) [x86_64-linux] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- Failed to install sqlite3 gem since 7f1ca666424849134990d022266bcd4d6636465f using Docker.
