将sh脚本交叉编译到enigma2 (mips) OpenEmbedded的bin中

Question

我有一个与Enigma2 OpenEmbedded一起运行的dreambox卫星接收器。所以MIPS架构。我想在我的Ubuntu PC上将一个.sh文件交叉编译成一个Enigma2二进制文件。

我在我的Ubuntu PC上为mips32架构安装了codesourcery交叉编译工具链。

工具链信息：

我使用SHC将.sh文件转换为.c文件，然后使用以下命令将该c文件交叉编译为mips二进制文件：

/mips-compiler/mips-linux-gnu-gcc -mips32 -o test.bin test.sh.x.c

没有看到错误(我非常高兴，但不幸的是(见下文))。然后将bin文件复制到我的enigma2机器中，并尝试执行它...

当我在MIPS机器上运行输出二进制文件时，我看到了以下内容：

./test.bin: line 1: syntax error: unexpected "("

所以很明显我在交叉编译命令中忘记了一些东西，但是什么呢？

在您生成的二进制文件上，file命令的输出是什么？

Answer 2

您不需要将shell脚本编译为C就可以运行它。只需将原始脚本复制到接收器并直接运行即可。
