seL4test/projects/musllibc/configure: not found

I have successfully executed repo sync，and ../init-build.sh -DPLATFORM=x86_64 -DSIMULATION=TRUE executed successfully. But when I do ninja, I get the following error:

Some questions:
Does the configure file in the path /home/wang/Documents/sel4/seL4test/projects/musllibc/configure exist?
What does repo manifest output?
What system are you running on?

[wangzhankun]

Yes, I find the error. Because after I clone the repo, the configure file is changed into CR mode. After I chang it into CRLF mode, it's all right.

Another question is why the file is changed into CR mode? I have to write a code to walk through all the files and change the '\r' into '\r\n'.

Here is my gitconfig:

[core]
        autocrlf = true
        filemode = false
[color]
        ui = auto
[url "https://githubcn.hgnet.workers.dev/google/boringssl.git"]
        insteadOf = https://boringssl.googlesource.com/boringssl
[url "https://ghp.quickso.cn/https://github.com"]
        insteadof = https://github.com

So what system are you running on?

\r sounds very strange. It should be all \n. \r\n would be Windows which is not supported as build host (you might be able to get it working, but we have not tried).

[wangzhankun]

I'm running on WSL2-ubuntu20.04. I use this command to change the \r.

sed -i 's/\r$//' $1

This is what happens when you clone/checkout on Windows and then switch into WSL. If you want to avoid this, either do the clone/checkout under WSL to begin with or use core.autocrlf=false when checking out or cloning under Windows.

[Ivan-Velickovic]

@wangzhankun does using the repo tool in WSL work for you? I can confirm that seL4test works for me in Ubuntu 20.04 running in WSL2, if I run all the commands inside WSL.

Ooh, that would be very nice to document on the host deps page!

[wangzhankun]

I clone the repo under WSL not on windows. And the repo tool works well on WSL.

Since a solution has been found, we can close this.
