I built Qt 5.10 as per [GitHub - jcfr/qt-easy-build at 5.10.0](https://github.com/jcfr/qt-easy-build/tree/5.10.0#readme)

I’m now trying to build Slicer, but I get the following compile error:

> [0%] Generating ui\_pqPlayBackEventsDialog.h

If I had to guess, I’d say that something didn’t build correctly when I built Qt? I can see the file

I am otherwise confused by

Any ideas?

Clarification: I’m running cmake with:

It looks like you are picking up a system Qt installation.

Hi Thomas,

I have no issue in compiling in ubuntu 17.10. I don’t know the reason of your error, but I can share my configuration (it may help):

1. I compile with gcc 6.4.0
2. I used Qt5.10 compiled with the Jc’s qt-easy-build script.
3. this is the string that I used to configure Slicer:  
cmake -DCMAKE\_BUILD\_TYPE:STRING=Debug -DQt5\_DIR=/home/davide/Slicer/Support/qt-everywhere-build-5.10.0/lib/cmake/Qt5 …/Slicer

In general I noticed that if you miss -DQt5\_DIR variable (and you setup the Qt5 paths later on, e.g. in ccmake), you can have issue.  
I hope helps

ah yes, I didn’t noticed the paths. Thomas, most likely you need to setup the Qt5 varibale in the cmake

Hi Thomas,

Why should you try to build it on Ubuntu. I just unpacked the tar-file and the I could run Slicer rightaway just from the slicer-file in the folder. Created a extra quicklauncher in the menu.  
Done!

p.s. I use LinuxMint (ubuntubased)

Greetings  
Léon

Thank you Davide and Isaiah,

Good catch. I’m not sure why it would be picking up a system installation. I am running Slicer build with:

> cmake -DCMAKE\_BUILD\_TYPE:STRING=Debug -DQt5\_DIR:Path=/media/vaughan/workspace/lnx/devel/Support/qt-everywhere-build-5.10.0/lib/cmake/Qt5 …/S4  
> make

This _should_ work, no?

yes, hopefully (🙂 .  
(however, I don’t use the :Path in front of the Qt5\_DIR variable)

P.S.: you can also use the -j option with make to speed up.  
e.g.: make -j 8

Thanks. 🙂 I usually use -j flag, I didn’t use it this time because I want to see the output one line at a time before the build stops.

To be clear, the issue is that I’m running this command:

> cmake -DCMAKE\_BUILD\_TYPE:STRING=Debug -DQt5\_DIR:Path=/media/vaughan/workspace/lnx/devel/Support/qt-everywhere-build-5.10.0/lib/cmake/Qt5 …/S4

Then make, and the build fails.

Correction: I’m not sure why I wrote Ubuntu 17.10 in the title. I’m actually running Pop!\_OS. I think it’s based on Ubuntu 17.10, but it might not be the exact same thing. I’ll correct the title.

Yes. I deleted everything in the Slicer build directory and ran these commands again to be 100% sure:

> cd S4D  
> cmake -DCMAKE\_BUILD\_TYPE:STRING=Debug -DQt5\_DIR=/media/vaughan/workspace/lnx/devel/Support/qt-everywhere-build-5.10.0/lib/cmake/Qt5 …/S4  
> make -j7

I got the same result.

All the Qt definitions I see in ccmake refer to my Qt build (in /media/vaughan/workspace/lnx/devel/Support/). So I’m not sure what’s going on… whether it’s a configuration problem or something gone weird when I built Qt5. As far as I can tell I haven’t deviated from the usual process.

In case it’s relevant here are the versions of various packages/builds I’m using:

- GCC: 7.2.0 installed through package manager
- Git: 2.14.1
- CMake: 3.11.0, built from source with openssl support
- Qt: 5.10.0, built using qt-easy-build
- Slicer: checked out commit [https://github.com/Slicer/Slicer/commit/6b1f058de4082c920f1ddf3abd61fee01e0b07c9](https://github.com/Slicer/Slicer/commit/6b1f058de4082c920f1ddf3abd61fee01e0b07c9)

sorry no idea, I had not these path issues. Here are my building differences:

These kind of issues seems to be due to ldd picking up system Qt. See for example [linux - Error on execution -version `Qt\_5' not found required by - Stack Overflow](https://stackoverflow.com/questions/36128645/error-on-execution-version-qt-5-not-found-required-by).

You can find build script that Slicer nightly builds use here: [GitHub - Slicer/DashboardScripts: Collection of scripts used to configure/build/test/package 3D Slicer and associated extensions](https://github.com/Slicer/DashboardScripts)

Thanks @lassoan 🙏 !

I’m not sure where I am supposed to find the build script in the second link you sent. But the links still helped. I can get Slicer to compile now. I ran the following:

> cd S4D  
> export LD\_LIBRARY\_PATH=/media/vaughan/workspace/lnx/devel/Support/qt-everywhere-build-5.10.0/lib  
> export PKG\_CONFIG\_PATH=/media/vaughan/workspace/lnx/devel/Support/qt-everywhere-build-5.10.0/lib/pkgconfig  
> export PATH=/media/vaughan/workspace/lnx/devel/Support/qt-everywhere-build-5.10.0/bin:$PATH  
> cmake -DCMAKE\_BUILD\_TYPE:STRING=Debug -DQt5\_DIR=/media/vaughan/workspace/lnx/devel/Support/qt-everywhere-build-5.10.0/lib/cmake/Qt5 …/S4

And the rest of the build was ok. 👍 Edit: Though inconvenience that I have to export the LD\_LIBRARY\_PATH to run Slicer from Terminal.

Normally setting the Qt5\_DIR in CMake should be enough though… no?

Edit again: I’m going to try setting the path variable similar to [here](https://discourse.slicer.org/t/build-failing-in-ctk-on-macos-10-12-slicer-nightly-qt-5-9/2551/17).

From the first message, it seems like the problem is higher, at the Qt build level: the `uic` program is linked against system Qt libraries rather than against the libraries in its build tree:

> /media/vaughan/workspace/lnx/devel/Support/qt-everywhere-build-5.10.0/bin/uic: /usr/lib/x86\_64-linux-gnu/libQt5Core.so.5: version `Qt\_5.10’ not found (required by **/media/vaughan/workspace/lnx/devel/Support/qt-everywhere-build-5.10.0/bin/uic** )

So the problem is potentially with Qt or the qt-easy-build discovery process rather than Slicer per se. (but the only thing I can think of is maybe you have LD\_LIBRARY\_PATH set already, for a Nix or multi-arch configuration? then ld might defer to those during build as in the link from Andras).

@tavaughan I just upgraded to ubuntu 18.04 (completely clean installation) and I had the same issue.

Config:

- GCC 7.3.0
- cmake 3.10.2
- git 2.17
- qt from Jc’s script

If I have time I’ll try to donwgrade gcc and see if the linker will work properly.  
Setting manually the paths fix the issue as well.

@Davide_Punzo @tavaughan when you build with qt-easy-build, do you get QtWebEngine? Did you install anything other than the Slicer prerequisites?

I’ve built on two different systems, and didn’t get QtWebEngine either time. From [this list](https://wiki.qt.io/Building_Qt_5_from_Git#Linux.2FX11) it seems I was missing bison, flex, and gperf (at least)… trying again after installing.

@ihnorton, I had the same issue. I ended up with this post [https://www.ics.com/blog/how-compile-qt-source-code-linux](https://www.ics.com/blog/how-compile-qt-source-code-linux). For ubutnu 18.04 I had to change a couple of libraries, but then worked.

In addition, I noticed that I had to do a clean installation to get to compile the webengine (i.e., this workflow was not working: tried to compile, error, installing additional libraries, trying again to compile). It looked like the configuration script was not really looking again.

P.S.: at a cetain point the script print out the configuration building. This is mine after installing all the libraries in the post (and maybe few others) and doing again a clean building of Qt:

I guess that for Webengine these are the important ones:

Thanks. The set of dependencies from the ICS link seems to have done it. Now I get a listing for WebEngine in the configure output. Unfortunately as far as I can tell there is no way to make ./configure fail fast if webengine won’t be built ([https://github.com/jcfr/qt-easy-build/issues/40](https://github.com/jcfr/qt-easy-build/issues/40)).
