Qt 5 fails to build

[bjornfor]

The current mirror has only 5.15.x sources, not 5.12.x, so the download fails.

I tried using this patch:

diff --git a/pkgs/qt/default.nix b/pkgs/qt/default.nix

   };

   base_raw = crossenv.make_derivation {

(Notice how the hash changes -- ugh. I don't have the original tarball to compare.)

But then there is a new error:

$ nix-build -A win32.qt
these 2 derivations will be built:

Is my new tarball URL bad?

[DavidEGrayson]

Thanks for the report! The new URL for the same tarball seems to be:

https://download.qt.io/archive/qt/5.12/5.12.12/submodules/qtbase-everywhere-src-5.12.12.tar.xz

This is fixed in commit a57a608f4684894ec5605ae06ce9b07d3d6cfcb9.

Note that nixcrpkgs supports Qt 6 now, so you might want to try that instead! It should be better than Qt 5, since I didn't have to patch it as much and I didn't have to generate the CMake files myself using Ruby scripts.

nix-build -A win32.qt6.examples

Thanks!

nix-build -A win32.qt6.examples

That actually failed with missing /bin/pwd. I fixed it with this quick hack:

However, it failed to run under wine:

nix-build -A win32.qt.examples (qt5) worked though. This is very cool!

[DavidEGrayson]

I'm glad you like it! The /bin/pwd thing is now fixed in commit 20c54c9. I don't know much about Wine so I'm not sure what's going on there.

Thanks!
