dlltool：无法创建.lib文件：libpython27.a：无效的bfd目标

Question

我试图在Windows 7 x64上从libpython27.a构建一个64位版本的python27.dll。

按照这些instructions，我尝试了：

E:\temp>gendef python27.dll
 * [python27.dll] Found PE+ image

E:\temp>dlltool --as-flags=--64 -m i386:x86-64 -k --output-lib libpython27.a --i
nput-def python27.def
dlltool: Can't create .lib file: libpython27.a: Invalid bfd target

什么可以解释dlltool: Can't create .lib file: libpython27.a: Invalid bfd target？

dlltool版本：

E:\temp>dlltool -V
GNU dlltool (GNU Binutils) 2.23.2

Answer 1

我确实遇到了这个问题。我的MinGw安装了architecture = i686。这是默认选择，我忘了在安装过程中更改它。

通过使用以下标志安装MinGw解决了这个问题：architecture = x86_64, threads = posix, exception = seh。必须将MinGw\bin的路径添加到Windows的Path环境变量中。
