Building on Gentoo with recent Qt

I used to build the git source fine on gentoo with dev-qt/qtcore-4.8.6-r1 installed.
Since dev-qt/qtcore-4.8.7 I get the error

Code: Select all

qmake -r
Reading /home.crypt/massimo/opt/qcad/src/src.pro
 Reading /home.crypt/massimo/opt/qcad/src/3rdparty/3rdparty.pro
Project ERROR: Script bindings not available for Qt version 4.8.7. You can add them to src/3rdparty/qt-labs-qtscriptgenerator-4.8.7 or use another version of Qt.
Currently available Qt on Gentoo:

Code: Select all

[U] dev-qt/qtcore
     Available versions:  
     (4)    4.8.5-r2 4.8.6-r2 (~)4.8.7
     (5)    (~)5.4.1^t
Do I need to mask the 4.8.6 globally for building QCad? What version do I need? I can have some Qt4 and Qt5 slotted side by side, but not 2 of the Qt4. The old guide still says 4.8.4, isn't that outdated? Can I build a QCad with a local Qt in $HOME?

It seems this 3rdparty had some binary parts. In qt-labs-qtscriptgenerator-4.8.6 are .o files are "ELF 64-bit LSB relocatable, x86-64".
So I was just lucky in the past that I was able to build that on my platform with that 4.8.6..., now with 4.8.7 it's not possible and would not be possible on other architectures.

What is this 3rdparty? Can I disable parts, just to get a working basic QCad build?

No. There should not be any object files in a clean git checkout.

No, the script bindings are fundamental to QCAD.

You can likely use the bindings for Qt 4.8.6, just copy or rename qcad/src/3rdparty/qt-labs-qtscriptgenerator-4.8.6 appropriately. Don't forget to rename the file qt-labs-qtscriptgenerator-4.8.6.pro as well.

Thanks. I tried that before but I forgot to rename the file. Compilation worked now.
However the binary fails with:

Code: Select all

Fatal:    Cannot mix incompatible Qt library (version 0x40806) with this library (version 0x40807)

Looks like you have object or library files from an older Qt version still around. A full clean / make should help.

I forgot to say, this was a complete fresh clone from git.

There's definitely a Qt version mixup. This has nothing to do with sources but with already compiled libraries.

Again same question with todays recent libraries such as:

Code: Select all

dev-qt/qtbase-6.8.1
dev-build/ninja-1.12.1
sys-devel/gcc-13.3.1_p20240614
x11-libs/libX11-1.8.10-r1
x11-libs/libXrender-0.9.12
https://www.qcad.org/en/component/conte ... om-sources only describes building with Qt5 on Linux and Qt6 on Windows, but not with Qt6 on Linux. So I tried like this:

Code: Select all

$ cmake -DBUILD_QT6=ON -DCMAKE_BUILD_TYPE=Release -G Ninja .
$ ninja
$ release/qcad-bin
QCAD version  3.32.0.1
09:09:22: Debug:    loading plugins...
09:09:22: Debug:    loading static plugins...
Warning:  No script handler found...
What is missing, and what do I need to do with the required qcadjsapi/ and qtjsapi/ ?

Could you please provide a section how to build on Linux with Qt6?
As most distributions have dropped Qt5 and switched to Qt6, this is the way to go with system dependencies.

 As most distributions have dropped Qt5 and switched to Qt6, this is the way to go with system dependencies.
What is there against installing a recent trial version and removing the Pro Addons?
Currently that includes Qt5 and if that is dropped by Linux distributions doesn't matter at all.

Sure, that works.
Then it's just an academic question about how to do a custom build.

I get the exact same error. Compilation with QT6 works fine, but then qcad exists with

However in this response to "Compiling Qcad with QT6 under Linux" the user Matfie implies that it should work.

I was able to make some progress, but I am not yet finally there. The important thing is that with Qt6, the projects QtJsApi/ and QCadJsApi are mandatory. Those projects are mentioned in Compiling QCAD from Sources, Sec. "Checking out the QCAD Sources", but there is no further explanation what to do about them. :roll:

QCad needs a JS interpreter as the actual program logic and even the start-up code is written in Typescript. Without a JS interpreter QCad simply does nothing, but terminates again, which yields the messages we all have seen. Qt5 has its own JS interpreter, Qt6 has not and hence the additional projects are needed. If you have a close look at main.cpp, there is no single code line which calls "exec" on the RSingleApplication object which inherits QApplication. Instead the code relies on the RScriptHandler which executes autostart.js. Without autostart.js being executed nothing happens. :roll:

Preliminary remarks before building:
  • The CMakeLists.txt unfortunately use some hard-coded paths, hence unless you want to spend a lot of time on patching CMakeLists.txt, the following assumptions must be followed:
    • The projects must reside in the directories qcad, qtjsapi, qcadjsapi within the same parent directory.
    • You must use an in-tree build, not an out-of-tree build as otherwise the linking step files
  • There is a bug in qcadjsapi:generator/cpp/rarc_wrapper.cpp:288: RArc::createTangential only needs 4 not 5 arguments, so remove the 5th argument (simply delete line 288).
Creating a debug build:

If you run QCad "./qcad/debug/qcad-bin" now, you will see a lot of more messages and even the splash screen appears shortly. However, there is still a bug which I wasn't able to figure out:

The script file fails and unfortunately there is no easy way for me to debug this as QCad itself interprets "autostart.js". So GDB is of now help here, because it is not inside the C++ code. The error message also does not indicated which line of autostart.js is the broken one.

Not going into details of building QCAD from sources because I use a standard installation and simply won't get involved. :wink:

 RArc::createTangential only needs 4 not 5 arguments
That is a very recent update, see Commit b0c6b26 intended to have a variable radius depending on the endpoint.
Probably to enhance ArcTangential.js but it is not really used (next commit).

I think that you need to use the latest stable release for building.


In 2023 I posted an enhancement of ArcTangential.js that reverted to auto with an invalid radius.
It was never adopted.
Recently something similar popped up for drawing polylines.
I see this as how Andrew is going to support a variable radius for tangentially connected Arcs.

Right. The errors only exist in the HEAD of the master branches. If one clones the latest tagged version, everythings works on Gentoo with Qt6 :D Here are all commands for a Release build:

Code: Select all

git clone --depth 1 --branch v3.32.2.0 [email protected]:qcad/qcad.git
git clone --depth 1 --branch v3.32.2.0 [email protected]:qcad/qtjsapi.git
git clone --depth 1 --branch v3.32.2.0 [email protected]:qcad/qcadjsapi.git

cd qcad
cmake -DBUILD_QT6=ON -DCMAKE_BUILD_TYPE=Release -G Ninja .
cd ..

cd qtjsapi
cmake -DCMAKE_BUILD_TYPE=Release -G Ninja .
cd ..

cd qcadjsapi
cmake -DCMAKE_BUILD_TYPE=Release -G Ninja .
cd ..

cd qcad
ninja
cd ..

cd qtjsapi
ninja
cd ..

cd qcadjsapi
ninja
cd ..
Just fo be saved, the important remarks again:
  1. The project directories must be "qcad", "qtjsapi" and "qcadjsapi" and reside in the same parent directory.
  2. Only an in-tree build is supported.
Then run QCad with

Code: Select all

./qcad/release/qcad-bin
Next step is to write an ebuild.
