"没有这样的文件或目录"运行动态链接的ARM可执行文件时出错

我正在为运行Ubuntu 15.04的ARM嵌入式Linux平台进行交叉编译。以前的,静态链接的,这个程序的版本运行得很好。最近我需要链接libproprietary(这个问题更改了lib名称),它只能作为.so。

libproprietary.so有效;我可以运行一个依赖它的不同程序。

$ uname -a
Linux <hostname> 3.10.92-71 #1 SMP PREEMPT Fri Dec 18 00:38:54 BRST 2015 armv7l armv7l armv7l GNU/Linux

问题:

$ ./myprogram
-bash: ./myprogram: No such file or directory

我尝试过的事情:

$ ldd ./myprogram
libproprietary.so.2 => /usr/lib/libproprietary.so.2 (0xb6bbc000)
librt.so.1 => /lib/arm-linux-gnueabihf/librt.so.1 (0xb6ba6000)

libudev.so.1 => /lib/arm-linux-gnueabihf/libudev.so.1 (0xb690f000)

似乎解释器/usr/lib/ld.so.1不存在。我猜它应该与/ bin / ls使用的类似:

$ readelf -l /bin/ls | grep interpreter
  [Requesting program interpreter: /lib/ld-linux-armhf.so.3]

我不知道如何在我的链接步骤中解决这个问题。

ccache arm-linux-gnueabihf-g++ -o myprogram -static -Wl,--whole-archive -lpthread -Wl,--no-whole-archive -Wl,-no-undefined -pthread -Wl,-Bdynamic -lproprietary -Wl,-rpath-link=result/debug/lib -Wl,-rpath=\$ORIGIN/../../../../result/debug/lib variant-dir/debug/core-.o -Lresult/debug/lib -Wl,-Bstatic -l<other libs> 

我确实试过在核心.o字之后移动-Wl,-Bdynamic -lproprietary,但这并没有改变任何东西。

正确。您可以通过在链接时添加-Wl,--dynamic-linker=/lib/ld-linux-armhf.so.3标志来更改解释器。

然而,

  • 您的工具链可能会定位到您实际安装的libc的不同版本(在这种情况下程序可能会崩溃)。
  • 如果 定位正确libc,那么您的工具链配置错误。
