error: failed to stop process at REPL breakpoint

[WongChen]

Xcode 9.2 and macOS 10.12.6.

$ export PATH=/Library/Developer/Toolchains/swift-latest/usr/bin:"${PATH}"
$ swift
error: failed to stop process at REPL breakpoint

In xcode playground, I got no output.

[dan-zheng]

Playgrounds are known to be somewhat unstable, unfortunately. Could you please try restarting Xcode, or creating a new Playground?

[dan-zheng]

Sorry, I didn't address error: failed to stop process at REPL breakpoint. Did you install a pre-built toolchain from this page? If so, which version?

[WongChen]

@dan-zheng Yes, I tried both April 26, 2018 and May 3, 2018, got the same error: failed to stop process at REPL breakpoint error.

[dan-zheng]

I see. Is that the full error log? Do you have any more information?

I just noticed that you're using Xcode 9.2 - it may be the case that Xcode 9.3 is required. I'm not quite sure, but upgrading to 9.3 may fix the issue.

[WongChen]

@dan-zheng thx for your reply. How to see the full error log?

when I add -v using tensorflow-swift and default-swift:

  1>  

And Xcode 9.2 requires macOS 10.13, I will consider upgrading my system and Xcode.

[WongChen]

@dan-zheng thx for your reply. Maybe I'll just use the compiler and Xcode project. Later I'll move to Ubuntu.

[dan-zheng]

The REPL is error'ing at this line, I'm not sure why. 😕 I suspect upgrading to Xcode 9.3 will fix the error, since others haven't run into it. Sorry for not being more helpful!

[tyoc213]

Well Im on ubuntu and I get the same output

$ swift -v

@WongChen @dan-zheng

[dan-zheng]

Hmm, interesting. cc @marcrasi who's more knowledgeable about Ubuntu toolchains

[tyoc213]

I dont think it helps but just tried to build on ubuntu and got

[marcrasi]

@tyoc213, here are some things to check for the "failed to stop process at REPL breakpoint" error:

• Are you on Ubuntu 18.04?
• Have you installed all the packages listed here: https://github.com/apple/swift#linux ?
• If you make a simple swift file hello.swift with print("Hello World") and then call swiftc hello.swift and then run the binary ./hello, does that work? If it doesn't work, it might print out an informative error message that will give a hint about what's wrong.

The build error is happening because the swift build requires python 2. You could create a python2 virtualenv or conda environment, and try the build in that.

[tyoc213]

Yes, indeed and I have tryied to compile with those instructions.

My python installation is with conda the default environment is python 3, but I have setup conda activate old27 in .bashrc but after some time I get this error (which is a python 3 incompatibility as I know?)

Dont know if that helps... also should I continue posting here? or...?

And

Do you wish to build TensorFlow with CUDA support? [y/N]: No CUDA support will be enabled for TensorFlow.

How do I enable CUDA support?

It seems that it should locate the correct path of the 27 lib from the logs, but at the end it try to access string from py3...

[tyoc213]

@marcrasi I just downloaded the CPU version and it seems to work, but for the cuda version always shows that stop process at REPL breakpoint even on nightly build.

[marcrasi]

It sounds a lot like it's not finding cuda or cudnn libraries. Have you tried this:

If you make a simple swift file hello.swift with print("Hello World") and then call swiftc hello.swift and then run the binary ./hello, does that work? If it doesn't work, it might print out an informative error message that will give a hint about what's wrong.

It might print out a more detailed error message describing exactly what library it can't find.

@marcrasi I just downloaded the CPU version and it seems to work, but for the cuda version always shows that stop process at REPL breakpoint even on nightly build.

@tyoc213 did you solve this issue? because I have same issue in Ubuntu 18.04.

@marcrasi That works!!!, but then why i am getting that error?

[marcrasi]

Here's another thing to try that might reveal a more informative error message:

marcrasi@marcrasi:~$ swiftc -g hello.swift 
marcrasi@marcrasi:~$ lldb ./hello

[lakshya-sky]

@marcrasi i did same as you suggested and here is my output.

(lldb) target create "./hello"
Current executable set to './hello' (x86_64).
(lldb) b hello.swift:1
Breakpoint 1: where = hello`main + 15 at hello.swift:1:7, address = 0x0000000000000baf

but when I try to run:
