注意: 这个方式本身逻辑没有问题, 如果打包后无法运行, 应该是patchelf的bug. 类似llvm-dwarfdump这些程序都会出现这个情况. 后续会尝试用libelf自己写一个或者给patchelf提fix.
请大家有遇到这种情况时帮忙提issue到本工程.
Note that there is no logical problem with this method. If the packaged binary fails to run, it is likely a bug in patchelf. Similar issues have been observed with programs such as
llvm-dwarfdump. In the future, we will attempt to write a custom library usinglibelfor provide a fix for patchelf.If you encounter such issues, please help us by creating an issue in this project.
sopacker是一个用于打包可执行文件和动态库的脚本工程. 生成的新可执行文件可以在大部分Linux上运行.
sopacker is a script for packaging an executable file and all its dependent dynamic link libraries. The resulting executable can theoretically run on any Linux environment.
这个项目本身除了patchelf, binutils外没有依赖. 但是需要满足patchelf的依赖. 安装autoconf/automake即可. https://github.com/NixOS/patchelf/tree/c40128936fc804b74abddaa0bc1d8ef6e5dba48e
This project has no dependencies other than patchelf and binutils. However, the dependencies of patchelf need to be satisfied. Install autoconf/automake. https://github.com/NixOS/patchelf/tree/c40128936fc804b74abddaa0bc1d8ef6e5dba48e
apt install autoconf automake
除此以外需要binutils. 例如debian/ubuntu: apt install binutils
In addition, binutils is required. For example, on Debian/Ubuntu, run apt install binutils to install it.
第一次执行会update submodule并编译出patchelf. 如果有一个已经编译的patchelf, 则不会触发编译以节省时间.
The first time you run it, it will update the submodule and compile patchelf. If there is already a compiled patchelf in the root directory, it will not trigger the compilation.
Run ./packer -h to get the instructions:
Usage: ./packer [executable_file] [--output=output_dir]
executable_file: the path to the executable file
--output: (optional) the path to the output directory (default: ./output)
以bpftrace举例. 最新版本的bpftrace编译出的结果是不能在debian9上运行的.
For example, to package bpftrace:
./packer [bpftrace path]
一个新的bpftrace会出现在output这个文件夹中. 这个bpftrace就可以在debian9上运行.
A new bpftrace will be generated in the output folder in the current directory. This bpftrace is the packaged version and can be run on any environment.
修改所有的动态库和可执行文件里的解释器和动态库路径到本地.
Modify the interpreter and dynamic library path to the local path in all dynamic libraries and executable files.
打包出的新可执行文件实际上是个bash脚本, 后面带着所有已经修改过的动态库和可执行文件的tar包. 运行时将tar包解压到/tmp下的一个特定文件夹. 已经解压过则不解压. 最后执行/tmp下的可执行文件.
The resulting executable file is actually a bash script with a tarball of all modified dynamic libraries and executable files appended to it. When running, the tarball is extracted to a specific folder under /tmp. If it has already been extracted before, it will not be extracted again. Finally, the executable file under /tmp is executed.
