npm -v 和 node.js 在交叉编译的 nodejs0.12.2 上抛出非法指令

Question

我使用以下工具链为 Atmel SAMA5D36 交叉编译了 nodejs 0.12.2

export AR=arm-linux-gnueabihf-ar
export CC=arm-linux-gnueabihf-gcc
export CXX=arm-linux-gnueabihf-g++
export LINK=arm-linux-gnueabihf-g++

并配置和构建如下

./configure --without-snapshot --dest-cpu=arm --dest-os=linux --prefix=/home/root/nodejs-v0.12.2

制作 make install DESTDIR=/home/user/Desktop/nodejs_arm/nodebins

编译后的文件夹在/home/user/Desktop/nodejs_arm/nodebins/home/root里面生成

我将该文件夹压缩成一个 tar 文件并传输到 AtmelSAMA5D36 臂板。我在 /home/root 目录中的板上解压缩它并创建以下符号链接

ln -s /home/root/nodejs-v0.12.2/bin/npm /bin/npm
ln -s /home/root/nodejs-v0.12.2/bin/node /bin/node

当我使用 "node -v" 和 "npm -v" 测试它时，

"node -v" 给出正确的输出但是

“npm -v”抛出“非法指令”错误
与“节点”相同。

但是，交叉编译的 nodejs 0.10.40 运行良好。

非常感谢任何帮助。

我们在尝试通过 SAMA5D31 上的 buildroot 工具链使用 nodejs 6.1.0 时遇到了类似的问题，并且遇到了相同的“非法指令”问题。最后我们切换到使用版本 0.10.45，它包含在 buildroot 中，用于旧处理器（armv5 和更早版本）。

在解决此问题时，问题似乎出在 node 使用的 nodejs 和 OpenSSL 库中，其中编译的代码试图使用 Neon 指令进行浮点运算。 SAMA5D3X 处理器报告为 armV7，但没有 Neon FPU。然而，nodejs（以及我们的 openssl）正在尝试使用 Neon 指令，因为它假定它具有它们的 armV7。在 nodejs 可以处理非 Neon armV7 之前，最好的选择是使用 0.10.40 或 0.10.45 版本的 node，直到可以解决。或者自己修改node的构建配置来处理非Neon armV7。
