Compilation testers needed

[chennes]

In PR #7647 I am making some changes to our cMake scripts as the first step toward supporting Qt6. Most critically, however, is that I need to not break everyone's current Qt5 compilations! I'd appreciate some additional testers who could check out that PR and try compiling it on their system and report back the results. You should be able to compile the same way you always have, with no apparent changes. So, if you are a self-compiler and you find yourself just sitting around today thinking "gee, I wonder how I can help out with FreeCAD"... now is your chance .

If you don't know how to check out a GitHub PR using git, here's a quick set of steps to get you up and running. I assume you already have a clone of the main repo, represented by the "FreeCAD-src" directory name below (change the name as needed, obviously). If that's not the case, start with a git clone https://github.com/FreeCAD/FreeCAD FreeCAD-src before the following).

Code: Select all

cd FreeCAD-src
git fetch origin pull/7647/head:pr/7647
git worktree add ../FreeCAD-pr7647-src pr/7647
cd ../
mkdir FreeCAD-pr7647-build
cd FreeCAD-pr7647-build

At this point you have a new checkout of PR 7647 that won't interfere with your original FreeCAD. Run cMake and your compiler however you usually do.

If you are feeling really adventurous you can see if cMake runs properly with FREECAD_QT_VERSION set to 6 -- it won't compile, but cMake should run (possibly after you set Qt6_DIR to your installation location, and also possibly after installing PySide6 via pip or your system package manager).

Please report back your system details and results either here or in that PR.

I was able to successfully build and run the tests following the instructions above. I'd try to do your QT6 ask, but I'm not sure what results to post (if I could even do what was asked). Can I have QT5 and QT6 installed through my package manager (apt) without breaking things?

Build command:

Code: Select all

make -j$(nproc --ingore=2)
cd bin
FreeCAD --run-test 0

Let me know if you need more details.

Jake

Thanks for testing, that's exactly what I need.

Can I have QT5 and QT6 installed through my package manager (apt) without breaking things?

I can't make any promises about the compilation of non-FreeCAD software, but FreeCAD's compilation will work just fine if you have Qt5 and Qt6 both installed. For right now, it will auto-select Qt5, but can be overridden by setting FREECAD_QT_VERSION to 6 either in the cMake GUI or your cMake command line (e.g. cmake -DFREECAD_QT_VERSION=6 ../FreeCAD-pr7647-src). To test that you just want to make sure cMake runs to completion and prints out the appropriate Qt6 version information in the summary report. No point in trying to compile it .

IMO your package manager should warn you, if two packages can't be installed at the same time.

I get the following error:

Code: Select all

CMake Error at /usr/lib64/cmake/Qt5/Qt5Config.cmake:28 (find_package):
  Could not find a package configuration file provided by
  "Qt5WebEngineWidgets" with any of the following names:

    Qt5WebEngineWidgetsConfig.cmake
    qt5webenginewidgets-config.cmake

  Add the installation prefix of "Qt5WebEngineWidgets" to CMAKE_PREFIX_PATH
  or set "Qt5WebEngineWidgets_DIR" to a directory containing one of the above
  files.  If "Qt5WebEngineWidgets" provides a separate development package or
  SDK, be sure it has been installed.

I have this package installed, so it looks like the path is missing:

Is there a separate -dev package for QtWebEngine available and installed? Or does Fedora have a separate QtWebEngineWidgets package?
Can you see if you have a QtWebEngineWidgets dir where your cmake config files are stored, i.e. /usr/lib/cmake/Qt5WebEngineWidgets and it contains a file Qt5WebEngineWidgetsConfig.cmake. Could this file be located in another path?

This was the issue, thanks. qt5-qtwebengine-devel must have been removed somehow.

Anyway, compiles fine here

I get this with the QT6 build:

Haha, that's what I get for writing code in the editor here, instead of using an actual command line! Yes, of course you're right -- I'll edit the post.
