Question

我尝试在CentOS 6.5服务器上通过pip install annoy安装annoy，但收到以下错误。任何的想法？我在here中找到了VBROADCASTSS，但仍然不知道如何解决这些错误。

Answer 1

我使用gcc -march=native -Q --help=target来比较几台Linux机器上的gcc设置。我发现主要区别在于失败机器上的-march行是haswell，而其他行则是core... 像CentOS release 6.5 (Final)这样的东西。这是其他服务器的相应输出：

-march=corei7-avx - CentOS Linux 7 (Core)

-march=core-avx-i - Debian GNU/Linux 7 (wheezy)

-march=core-avx2 - setup.py

我猜错误来自gcc使用的不同指令集。在恼人的-march=native中，行extra_compile_args=['-O3', '-march=native', '-ffast-math']中的-march=corei7-avx表示gcc将尝试检测处理器并自动为其设置适当的标记。因此，我将此标记更改为setup.py中的-march，错误消失了。

如果您有兴趣，请参阅here中的binutils了解详细信息。

更新

在与服务器管理员确认后，此错误是由于CentOS加载程序软件比服务器中的新Haswell CPU更旧。安装最新版本的val createUserForm = Form( tuple( "username" -> text, "password" -> text, "role" -> text ) ) def createUser = Action { implicit request ⇒ var (username, password, role) = createUserForm.bindFromRequest.get println(username, password, role) }包也可以解决问题。

Answer 2

您的binutils版本太旧，无法支持AVX / AVX2指令，这些指令已在处理器上检测到。您需要binutils 2.22或更新版本才能获得AVX支持。

错误：后缀或操作数对于`vbroadcastss＆＃39;无效
