安装系统失败。Win32.Com
Failed to install System.Win32.Com
我 运行 虚拟化 Windows 7 x64。 System.Win32.Com 软件包安装失败。如何解决问题？

Configuring com-1.2.3.1...
cabal: Bad header file: include/comPrim.h
The header file contains a compile error. You can re-run configure with the
verbosity flag -v3 to see the error messages from the C compiler.
Failed to install com-1.2.3.1
cabal: Error: some packages failed to install:
com-1.2.3.1 failed during the configure step. The exception was:
ExitFailure 1
运行 -v3 选项给出如下错误：
In file included from C:\Users\Leo\AppData\Local\Temp2536868.c:3:0:
./include/comPrim.h:123:1: error: expected '=', ',', ';', 'asm' or
'__attribute__' before 'OleInitialize'
OleInitialize ( void* pvReserved );
^
./include/comPrim.h:128:1: error: expected '=', ',', ';', 'asm' or
'__attribute__' before 'OleUninitialize'
OleUninitialize ();
^
...
此外 -v3 选项表示找不到某些包。会不会是这个原因？我只列出其中的几个。

cabal甚至不知道其中的一些（例如hmake）。

您正在使用不兼容的 C 编译器构建，例如 x86_64-w64-mingw32 工具链
与 MinGHC installer for GHC 7.10.2 (64-bit) 一起安装。
它将产生您所看到的错误。与MinGHC installer for GHC 7.10.2 (32-bit)一起安装的mingw32
不会生产它们。
使用 32 位 GCC 构建包意味着您可以在 64 位或 32 位上构建它 Windows 并且
它将在 64 位或 32 位 Windows 上执行，但你不能 link 32 位与 64 位包库一起使用。
这可能是学术性的，但是，因为使用 32 位构建此程序包 (cabal install com)
