Add docs for enabling git symlinks (originally Repository build fails (Windows))

[uafcybs]

Add documentation that git needs symlinks enabled for Windows otherwise errors occur.

• Add to README
• Add to book

Original description

I've been trying to build "out of the box" repository as suggested in the README file with trivial cmake commands.
It always failed for cargo_without_cmake project:
build_log.txt
Rust - 1.66.1
C++ - MS VS 2022
CMake - 3.24.3

Are there any other things to consider besides those listed in the README?
Thanks in advance

Hi Magnus Thanks for the answer The value of core.autocrlf is input. (I checked files to be sure – they have 0x0a line endings) Unfortunately the path did not help as well. Please let me know if I can do something to find a root cause Regards Igor

In addition to my last email – there are some files with Windows line endings: * moc_* files * *.h files in vcpgk Not sure if it’s relevant though Regards Igor

In addition to my last email – there are some files with Windows line endings:
moc_* files
*.h files in vcpgk

The build script doesn't analyze those files to generate code, so those are probably not relevant to this bug. Have you tried the suggested patch?

What version of Windows are you using? You may need to enable developer mode for the symlinks in this repository to work.

[uafcybs]

Yes, I tried it Unfortunately – does not help…

[uafcybs]

It’s Windows 10. Enabling developer mode did not help … Regards Igor

Have you tried the suggested patch?

I realized find('\n') would also find the \n in \r\n and thus work correctly, so it's nothing with line endings after all (hence my deleted comment).
Would need to investigate closer with Windows, I can't see anything now that wouldn't work in Windows at a quick glance.

Enabling developer mode did not help …

Did you delete and re-clone this git repository after enabling developer mode?

[uafcybs]

No, just “build” folder and repeated both cmake steps… Gonna try re-clone later . Thanks for the tip!

Clear/re-clone did not help

What are the contents of the file cxx-qt/examples/cargo_without_cmake/src)/cxxqt_object.rs?

Make sure Git has symlinks enabled by running git config core.symlinks true

Make sure Git has symlinks enabled by running git config core.symlinks true

This helps, thank you!

It might be helpful for some other Windows users to mention this symlink related stuff in the README.md.
It is also built out of the box only with --config Release in my case. With default (Debug) configuration the build ends up with lot of linker errors regarding the different debug info levels in object files/libraries.

I think it would be a good idea to note this somewhere in the README and/or book so lets re-open this issue to track that.

I added that to the README here: #439
