[ruby-core:124680] [Ruby Bug#21862] dtrace is passed unmodified CPPFLAGS, but not all compiler flags are supported by dtrace
Issue #21862 has been reported by wiz (Thomas Klausner). ---------------------------------------- Bug #21862: dtrace is passed unmodified CPPFLAGS, but not all compiler flags are supported by dtrace https://bugs.ruby-lang.org/issues/21862 * Author: wiz (Thomas Klausner) * Status: Open * ruby -v: 4.0.1 * Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN, 4.0: UNKNOWN ---------------------------------------- I use "CPPFLAGS=-g" to enable symbols in my builds.
