为 Chrome 的便携式本机客户端 (PNaCl) 构建错误移植 Eigen3 库

Question

所以我有一个 AWS 实例（免费一级）运行 Ubuntu 16.04。在那里我安装了 nacl_sdk （它正在工作并且允许我成功访问他们的示例站点）和我用来移植 opencv 的 naclports 由于 zlib 的错误我一开始遇到了麻烦但它工作了在我添加 i386 架构并在系统上执行 sudo apt-get update 并安装必要的 i386 程序之后。

注意我也安装了 depot_tools。

现在我也在尝试为 pnacl 安装 eigen3 库，但我遇到了一个错误，我不确定如何理解它，也不知道它是如何构建来修复它的。

我移植 opencv 的命令是

$ NACL_ARCH=pnacl make opencv

我尝试了这两个命令来构建 eigen3，结果相同（如下所示）

$ NACL_ARCH=pnacl make eigen3
$ bin/webports install eigen3

这是终端输出的最后（整条消息很长）：

Answer 1

clang: error: unable to execute command: Killed

看起来您的 AWS 实例 killed clang，所以它可能运行内存不足。免费套餐提供 1 MiB 内存，这可能不足以满足您的需求。
