[ruby-dev:789] configrb

わたなべです.

install script を書こうと思うと,
どうしても config.rb が必要だと感じてしまったので,
config.status から config.rb を作る configrb を作りました.
perl5 のまねです.
INSTALL 等処理を省略してるとこは手を抜いてます.
いい方法が思い浮かばない.

$CONFIG['bindir'] = '/usr/local/bin' のような感じになってるけど,
C_bindir = '/usr/local/bin' のほうがいいかな?

で, これを実行すると SEGV になります.
DEFS の行が長くて,
  if /^s%@(\w+)@%(.*)%g/
のところで落ちてるみたいです. とりあえず regex.c の NFAILURES
を 100 にしてごまかしてます.
