使用 MinGW/MSYS 编译 freetype2 时出现问题

用MinGW和MSYS编译freetype2好像有问题

我对 freetype 源代码的干净副本以及纯粹的 MinGW 和 MSYS 的尝试给出了：

Andrew@MCARDLE-PC ~/documents/code
$ cd freetype-2.3.11

Andrew@MCARDLE-PC ~/documents/code/freetype-2.3.11
$ ./configure

FreeType build system -- automatic system detection

The following settings are used:

  platform                    unix
  compiler                    cc
  configuration directory     ./builds/unix
  configuration rules         ./builds/unix/unix.mk

If this does not correspond to your system or settings please remove the file
`config.mk' from this directory then read the INSTALL file for help.

Otherwise, simply type `c:/code/mingw/bin/make' again to build the library,
or `c:/code/mingw/bin/make refdoc' to build the API reference (the latter needs
python).

在我看来，这两个问题似乎是 sed 无法识别“C”，并且找不到 libtool。

解决方案是删除 C:\mingw\bin\sed.exe，以便改用 MSYS sed。
