Hi,
Thanks Watanabe-san. Problem was that a cygwin install with
"Current" setup has gcc 2.95 and corresponding mingw libs.
By explicitly installing latest versions of gcc and mingw
latest ruby 1.8.0 can now be compiled and installed without
problems.
There seems to be troubles when building extension
libraries now though. Sorry for repeatedly bugging you
but I’m new to building ruby with mingw instead of cygwin
and don’t fully understand whats happening. I imagine
the following problem stems from different version of
include files available but don’t know:
$ ruby -v
ruby 1.8.0 (2003-01-27) [i386-mingw32]
$ pwd
/tmp/ruby-zlib-0.5.1
$ ruby extconf.rb
checking for deflateReset() in -lz… yes
checking for zlib.h… no
$ ruby extconf.rb --with-zlib-include=/usr/include
checking for deflateReset() in -lz… yes
checking for zlib.h… yes
checking for block_given?.. yes
checking for rb_str_buf_new()… no
checking for rb_io_print()… no
checking for rb_io_printf()… no
checking for rb_io_puts()… no
checking for rb_io_addstr()… no
checking for new NORETURN… yes
checking for new allocation framework… yes
guessing OS_CODE… Win32
** Attention:
** If you find auto-detected OS_CODE is seem to be different
** from your platform, please report it as a bug.
