Recently, I have been wicked. I have run several `actix` projects, and it prompts `Process startup failed: unknown error`

project address:

2021-5-6 11:13:45
I found that the same is true for compiling another project.

Windows 10.

println!("start!") is not executed. What is the situation?

Google searched for similar problems, but I still don't know how to solve this problem.

I use Clion.

Are you sure you copied those examples correctly?

print isa macro, and as such it must end with an exclamation mark to be valid syntax: print!("Starting program")

It should probably println!("start!"); not print("start!"); or print!("start!");. print doesn't write a trailing newline and because stdout is line buffered, this means that nothing is actually written to the terminal until a newline.

@bjorn3 @moy2010 I accidentally made a mistake. It’s a little strange that if you make a mistake, doesn’t it mean that the compilation has failed? Why compile? Do you have a Win10 computer? Try to compile?
Changing to println still has problems.

From what I can tell the Rust compiler created an exe file successfully. It's the IDE and/or its debugger trying to use it that is causing an error.

I would check whatever configuration settings the IDE is using. In VSCode this would be in .vscode. Maybe just remove whatever isn't working and try to start fresh with a minimal config. You might also find a better error message in the output of the debugger.

I don't use CLion but I understand those JetBrains IDEs have support channels for customers. They or their community might be of more help.


One thing I found was that I ran the compiled program directly, and there was no output, not even the first line of code.

I found out the reason,

First execute cargo run

D:\rust_project\actix_example\basics\todo>cargo run
Finished dev [unoptimized + debuginfo] target(s) in 0.64s
Running D:\rust_project\actix_example\target\debug\actix-todo.exe
error: process didn't exit successfully: D:\rust_project\actix_example\target\debug\actix-todo.exe (exit code: 0xc0000

Open the directory where the exe is located, D:\rust_project\actix_example\target\debug\ According to STATUS_DLL_NOT_FOUND , it is because the dll cannot be found, so it cannot be opened. Then double-click to run the exe directly, the prompt is as follows


Then find this file and put it into the directory where the exe is located.

It looks like whichever crate tries to use libintl-8.dll (possibly some wrapper around gettext) hasn't told rustc how to link to it properly. I'd create a ticket against their issue tracker because they probably need to add some println!("cargo:rustc-link-lib=intl-8") calls to their
