Build error (QT 5.15) under Gentoo

[msdobrescu]

Hello,

Under Gentoo, building it with QT 5.15, I get:

level=warning msg="failed to patch binaries\r\nyou won't be able to simply \"go build/run\" your application, but qtdeploy-ing applications should work nevertheless" error="exit status 1" level=error msg="failed to run command" _func=RunCmd cmd="5.13.0/gcc_64/bin/qmake -query QT_INSTALL_PREFIX" dir= env= error="fork/exec 5.13.0/gcc_64/bin/qmake: no such file or directory" name="query install prefix path for linux on linux"

Well, is there a way to build against QT 5.15?
If so, how?

Hi :)
Thank you for reporting the issue.

I appreciate this report as I have never attempted to build with Gentoo.
What procedure are you trying to build and at what step of the procedure is the error occurring?

By the way, the error message you reported shows the following error:

fork/exec 5.13.0/gcc_64/bin/qmake: no such file or directory　

This indicates that the mechanism provided by qt bindings could not find the qmake command. in special cases where the qmake command is not in the expected location, the following environment variable can be used to directly specify the command path. Try to identify the path to the correct qmake command in the installed qt5 package and specify that path in the following environment variable.

export QT_QMAKE_DIR=/path/to/emake_dir

Hi, I basically do this:

git clone https://github.com/akiyosi/goneovim
cd goneovim
git fetch --all --tags
git checkout tags/v0.6.8
make qt_bindings
make deps
make app

How about specifying QT_QMAKE_DIR ?

[msdobrescu]

To what? On the build system I have qmake in /usr/lib64/qt5/bin/, but that does not seem to help at all.

[akiyosi]

In that case, do the following:

export QT_QMAKE_DIR=/usr/lib64/qt5/bin

[msdobrescu]

This went a bit further:

github.com/akiyosi/qt
github.com/akiyosi/qt/core
github.com/akiyosi/qt/core
core.cpp:67:10: fatal error: QExtensionFactory: No such file or directory
67 | #include <QExtensionFactory>
    |          ^~~~~~~~~~~~~~~~~~~
compilation terminated.

level=error msg="failed to install 'core'; aborting setup"
make: *** [Makefile:70: qt_bindings] Error 1

@msdobrescu How did you install the qt5 package?

[msdobrescu]

Is QExtensionFactory part of the QTDesigner? If so, MocaccinoOS (built on Gentoo) does not have it by default. Is this a build only dependency? I will add it to my build chain and come back! Thanks for your patience!

[msdobrescu]

That helped. Now it fails at:

github.com/akiyosi/qt
github.com/akiyosi/qt/core
github.com/akiyosi/qt/core
core.cpp:155:10: fatal error: QRemoteObjectPendingCallWatcher: No such file or directory

compilation terminated.

[Makefile:70: qt_bindings] Error 1

@msdobrescu
Try the following:

QT_PKG_CONFIG=true QT_API=5.13.0 /path/to/qtsetup

[msdobrescu]

I think the above error shows it needs pyside2, but I can't build it without some tricks.
Regarding the paths, please provide some directory or binary name to look for in order to identify them in the Gentoo setup.

I asked ChatGPT and was guided through the following steps. How about trying this?

1. Install dev-qt/qtremoteobjects:

The missing file likely belongs to the qtremoteobjects package. You can install it by running:

sudo emerge dev-qt/qtremoteobjects

2. Sync and Update System:

If the package is not available or the error persists, ensure your system is up-to-date and properly synced:

sudo emerge --sync
sudo emerge -avuDN @world

[msdobrescu]

So far I could use the binary, but now there it is missing a specific version of the tiff lib, so building is the only choice:

    libtiff.so.5 => not found

I'll try and come back. Thank you!

Ah, so that's the situation.
