在其他Linux计算机上运行已编译的Linux可执行文件

Question

I've been working on a custom program that allows me to control my other Linux-based computers on my network. I've been using Python and used PyInstaller to compile the code into a Linux executable. Running the executable on my own computer works just fine and does exactly what it's supposed to. But once I send it over to another computer to test it, I get this error.

ImportError: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.25' not found (required by /tmp/_MEIXcUz91/libudev.so.1)
[3716] Failed to execute script RP

And the command I used to compile the code with PyInstaller

python pyinstaller.py -D -F -n RP -c RP.py

Again, the executable runs perfectly on the computer I used to create and compile it, but once I send it over to my other Linux-based computer and execute it, it crashes.

Answer 1

The problem is that you have different C system libraries on the two machines. There can sometimes be difficulties when porting a pre-built binary. Either you ensure that you're using a similar environment or you put all dependencies into the binary - this may increase its size significantly. To do the latter you need to use the ´--static´ keyword during compilation. I'm not sure, though, whether this is enough.

EDIT:

Since this is a pure Python project, you should make sure that the used Python version is compatible, ie, same Python version and also the same Python build (CPython, etc.).

Answer 2

use ldd if you file is RP ldd RP - looking for dynamice so libraries used by the executable if you can change the linking of your program to static libraries, may be able to make more portable else you will have to stay on same release of linux to run your program. You could also package the .so dependencies with your executable,but messy.
