# Alien::TinyCDB build recipe (Alien::Build path).
#
# Provides Michael Tokarev's TinyCDB (corpit.ru cdb) C library to Perl
# consumers through cflags / libs / dynamic_libs. Probe for a usable system
# install first; otherwise fetch upstream and build from source.

# System detection: upstream's `make install` ships a pkg-config file
# (libcdb.pc), so pkg-config is the honest probe + sys gather. If a usable
# system TinyCDB is found the share block below is skipped entirely.
plugin 'PkgConfig' => (
  pkg_name => 'libcdb',
);

share {

  # Upstream is fetched at build time, not vendored, and the version is NOT
  # pinned: pick the newest tinycdb-<version>.tar.gz the directory lists.
  # This mirrors the previous Alien::Base::ModuleBuild alien_pattern_* keys
  # (prefix tinycdb-, version ([\d.]+), suffix \.tar\.gz) against alien_repo.

  # TinyCDB ships a plain hand-written Makefile (no ./configure). Its default
  # `all: static` target builds only the static libcdb.a plus the cdb binary;
  # the shared library lives behind the separate `sharedlib` (build) and
  # `install-sharedlib` (install) targets, which upstream marks GNU CC/LD
  # specific (-fPIC / -shared). Build and install BOTH the static archive and
  # the shared object, so that ->libs links libcdb.a and ->dynamic_libs finds
  # libcdb.so for FFI::Platypus. %s-style prefix is supplied by Alien::Build
  # as the staging install prefix; never hardcode a path.

  # FFI) cleanly separate.

  # the staging prefix to the final dist_dir at runtime (see Alien::Base
  # _flags relocation), so these stay correct after install.
