Qt 5.11.2 fails to build in Visual Studio 2017

[mleotta]

Fletch build fails with Qt 5.11.2 on Windows (Visual Studio 2017). The error seems to be this known issue:

https://bugreports.qt.io/browse/QTBUG-66652?attachmentSortBy=dateTime

I suppose we will need to find a patch for this.

According to that link, the build should fail when the path to the QT base directory is 63 or more characters. Our dashboard comes in at 67 characters... I shortened the path and I am running the dashboard now to confirm that this is indeed the problem. Looks like Qt doesn't even have a patch for this problem (yet).

Qt5 in KWIVER is in a weird state for me currently, I cannot seem to get version 5.11.2 to compile successfully on any platforms (win/mac/linux). I'd like to know if any others experience the same troubles..

I have built it with the latest msvc 2017 several times now

Taylor is correct. The build will work unless you extend the length of your build directory. There is apparently a setting in Windows 10 preview(?) that allows you to disable that restriction, though I can't imagine why it's not just the default. https://mspoweruser.com/ntfs-260-character-windows-10/ FWIW, we've had the same issue with Boost for a while now. I don't know if there is really any good solution other than, shorten your path or disable the NTFS silliness. It's a Windows limitation, not Qt or our build. At some point, every package will fail because if it, provided you make the build path too long.

My path to Qt has 62 characters, unless I'm counting wrong, and I hit this issue. C:\Users\matt.leotta\Software\fletch\bld-vs15-rel\build\src\Qt I could shorten my path, but I expect other KWIVER users would easily hit this bug if they put fletch in their home directory like I did.

Qt 5.11.2 is building successfully on VS2017. This success looks to be a result of limiting the build path, and a few patches to master.

Nightly: https://open.cdash.org/buildSummary.php?buildid=5586897

Can this issue be closed?

[mleotta]

If the solution requires that you build Fletch in a path of limited character length, then I think we need to document that requirement in the build instructions before closing this issue.

[dstoup]

I agree with Matt. Further, as long as that's the solution, I would prefer this ticket remain open as a reminder that the real solution needs to be found and integrated, even if it's just monitoring upstream to see if they have finally addressed it.
