Issue #8315 has been updated by Tomoyuki Chikanaga. Backport changed from 1.9.3: UNKNOWN, 2.0.0: UNKNOWN to 2.0.0: REQUIRED, 2.1: REQUIRED ---------------------------------------- Bug #8315: mkmf does not include include paths from pkg_config anymore https://bugs.ruby-lang.org/issues/8315#change-48755 * Author: Hans Mackowiak * Status: Closed * Priority: Normal * Assignee: Nobuyoshi Nakada * Category: ext * Target version: * ruby -v: trunk * Backport: 2.0.0: REQUIRED, 2.1: REQUIRED ---------------------------------------- #6504 does that, for cpp files `$CFLAGS` is not used anymore, so the problems are the include paths: * there is no `$CXXFLAGS` global variable defined * pkg_config does not add the includes paths to the correct `*FLAGS` so my gems are currently broken for ruby trunk and if i fix that it may be broken for the older ruby -- https://bugs.ruby-lang.org/
