How to configure QT6 static?

[TomZ]

@hsjeong a couple of things;

1. there is no need to compile statically as long as you simply deploy the generated dynamic libraries to your device.
2. you most likely need to cross-compile to the architecture of your embedded device. Are you sure it is running the same CPU as the one you compile with?
   Building for: linux-g++ (x86_64, CPU features: mmx sse sse2)
3. compiling as static means things like image plugins (jpeg/png etc) support is going to be missing. Are you sure you want to compile statically?

how to add liblzma.lib and other libraries to cmake?

[Peal Wang]

I use cmake directly and successful. This is my configure:

The key should be to specify libs using CMAKE_EXE_LINKER_FLAGS

is someone static compiling 6.8.2 in Windows 11 with VS2022 ?
I run the command

configure.bat -platform win32-msvc -release -static -static-runtime -prefix C:\Qt/Qt6.8.2/64 -commercial -confirm-license -plugin-manifests -nomake examples -nomake tests

I am able to compile version 6.8.1 but with version 6.8.2 I get many warnings and finally it compiles about 12000 lines (6.8.2) or source instead of about 18000 (6.8.1)

@rparon said in How to configure QT6 static?:

So, does the build succeed or not? The fact that it compiles less files can be related to what modules where activated when running configure script.

[rparon]

thank you for the comment,
yes, despite the many warnings (also requesting the folder of CLang) the compling process terminates and I able to run
ninja install
however whenI try to compile my project (QML + C++) the linking process terminates showing a strange error, see below ,cannot open input file '(.obj'

which seems strange as I am unable to locate a file name with this string / substring '(.obj' inside....

do you have any clue to solve this problem ?

[jsulm]

@rparon Did you do a complete rebuild after switching to that Qt version?

[rparon]

yes, I put the sources of Qt 6.8.2 in C:/Qt/6.8.2/64 and the library was compiled with VS2022 after executing

configure.bat -platform win32-msvc -release -static -static-runtime -prefix C:\Qt/Qt6.8.2/64 -commercial -confirm-license -plugin-manifests -nomake examples -nomake tests

then

cmake --build --parallel

ninja install

still I have previous version in C:/Qt/6.8.1/64 and C:/Qt/6.8.1/32 but I suppose there are no global vars which may cause conflicts...

[jsulm]

@rparon I'm not talking about building Qt, I'm talking about building your project

[rparon]

sure, it was the first think to do...

1. in build directory manually delete all files and folders (CMake cache,MOC files etc.etc.)
2. manually delete CMakeList.txt.user to force Qt Creator to redefine all the makefiles

you may imagine I was quite surprised to see exactly the same error reported -> LINK : fatal error LNK1181: cannot open input file '(.obj'

[rparon]

a possibility, which I have not investigated, is that Qt Creator or CMake may store something outside the build directory, but I am not aware of that...

[jsulm]

@rparon Then you should check your CMakeLists.txt file or post it here, so others can take a look. Something must be wrong there.

[rparon]

the cause was a bad format in module-definition (.def file) which, for unknown reasons, generated that error when linking ...
Now Qt 6.8.2 works fine, thank you for help.
