Clang 从Linux到Windows交叉编译gnustepbase

几周来，我一直试图在Arch Linux机器上使用mingw-w64进行交叉编译，但我陷入了困境。我能够编译libobjc2，并设置gnustepmake。对于gnustepmake，我使用了以下configure命令：

./configure --prefix=/opt/cross/windows/gnustep --host=x86_64-w64-mingw32 CC=clang CXX=clang++ CPPFLAGS=$CLANG_WIN64_XFLAGS --enable-objc-nonfragile-abi --with-layout=fhs --with-thread-lib=-lpthread

在gnustep基本目录的根目录中调整cross.config文件后，我运行configure:

CLANG_WIN64_XFLAGS的定义如下：

-target x86_64-w64-mingw32 -nostdinc -isystem /usr/lib/clang/3.6.0/include -isystem /usr/x86_64-w64-mingw32/include -isystem /usr/x86_64-w64-mingw32/include/c++/5.1.0 -isystem /usr/x86_64-w64-mingw32/include/c++/5.1.0/backward -isystem /usr/x86_64-w64-mingw32/include/c++/5.1.0/x86_64-w64-mingw32 -D_GNU_SOURCE=1

运行make后会发生此错误：

Making all for subproject Additions...
 Linking subproject Additions...
obj/Additions.obj/GSTypeEncoding.c.o: file not recognized: File format not recognized
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我通过运行git reset&&git checkout确保删除了所有旧的对象文件git clean-fdx，但我仍然得到这个错误

有人试过在Linux上使用mingw-w64构建gnustep库吗？任何帮助都将不胜感激
