# ---------------------------------------------------------------------------
# Install-time C build support.
#
# When Inline::C is usable at configure time (and IF_NO_C isn't set), the
# generated Makefile gains a rule that compiles the Inline::C backend once
# during `make` and installs the shared object with the distribution, so
# users never pay the first-load compile and need neither a C compiler nor
# the Inline modules at run time.
#
# The IF_* environment variables (IF_OPT, IF_ARCH, IF_NATIVE, IF_NO_OPENMP)
# are captured *now* -- set them when running `perl Makefile.PL`, not
# `make` -- and recorded in the generated
# Algorithm::Classifier::IsolationForest::BuildFlags module.  At run time
# those recorded values are the defaults: a process requesting the same
# flags loads the prebuilt object via XSLoader; one requesting different
# flags (or setting IF_RUNTIME_BUILD=1) falls back to the classic runtime
# Inline::C build under _Inline/.  Validation mirrors the module's own,
# since these values reach a compiler command line.

=head1 NAME

Algorithm::Classifier::IsolationForest::BuildFlags - C build flags captured at configure time

=head1 DESCRIPTION

Autogenerated by Makefile.PL.  Records the IF_* environment values that
were active when the distribution was configured, and whether a prebuilt
Inline::C object was scheduled for installation.  Read once by
Algorithm::Classifier::IsolationForest at load time; see "NATIVE
ACCELERATION" in that module's documentation.

=head1 FUNCTIONS

=head2 flags

Returns a hashref with the keys C, C, C, and
C.

# Appended to the Makefile when the install-time build is on.  Modelled on
# what Inline::MakeMaker generates, with two differences: only the one
# module that actually embeds C gets a rule (Inline::MakeMaker emits one
# per .pm in lib/), and install mode is signalled to the module via
# IF_INSTALL_BUILD=1 in the rule's environment instead of a global
# -MInline=_INSTALL_ import, so the module can pass Inline's _INSTALL_
# config itself alongside NAME/VERSION.  Inline's install mode reads the
# version and blib/arch destination from @ARGV.  The trailing -e writes a
# stub .inl file satisfying the make dependency (also what
# Inline::MakeMaker does); the compiled object itself lands under
# blib/arch/auto/ and is picked up by `make install`.
