Cannot install qt 6.7.0 prebuilt binary on Windows

[ABBAPOH]

What is your question?

Hello, I am trying to install Qt prebuilt binariy on Windows. Here's my profile:

[settings]
arch=x86_64
build_type=Release
compiler=msvc
compiler.cppstd=17
compiler.runtime=dynamic
compiler.runtime_type=Release
compiler.version=193
os=Windows

conan install --requires=qt/6.7.0

ERROR: Missing prebuilt package for 'qt/6.7.0'. You can try:
- List all available packages using 'conan list qt/6.7.0:* -r=remote'
- Explain missing binaries: replace 'conan install ...' with 'conan graph explain ...'
- Try to build locally from sources using the '--build=qt/6.7.0' argument

Tried setting options in the conanfile.py:

def config_options(self):
    self.options["qt"].qtdeclarative = False
    self.options["qt"].qtdoc = False
    self.options["qt"].qttools = False
    self.options["qt"].qttranslations = False

Same error.
I have run out of ideas, any help appreciated.

Hi @ABBAPOH

Thanks for your report.

I have been able to reproduce, first I also got the same "Missing binary" error, and then:

(conan2_310) λ conan graph explain --requires=qt/6.7.0 -s compiler.cppstd=17 -o qt*:qtdeclarative=False -o qt*:qtdoc=False -o qt*:qttools=False -o qt*:qttranslation=False

======== Computing dependency graph ========

        setattr(self.options, mod, True)
        ConanException: Incorrect attempt to modify option 'qtdeclarative' from 'False' to 'True'

This looks like a bug in the recipe in ConanCenter, not in Conan itself, I'll try to have a look.

From this comment https://github.com/conan-io/conan/issues/10104#issuecomment-982450067 it seems that one cannot modify props here https://github.com/conan-io/conan-center-index/blob/master/recipes/qt/6.x.x/conanfile.py#L215

Hi @ABBAPOH , thank you for reporting this. We have located the issue in the Conan Center recipe. Apologies for this - we will be more careful in the future.

I get the same issues with Linux. All the dependency options affect the package ID.

Hi @glennaycock - thanks for reporting this.

Looking to sort this out - however it's not ideal. We can set essential_modules=False for everyone, but that probably means reduced functionality Or we can set essential_modules=True, but we maintain too many qt versions and this has a severe impact on our CI.

While we address this, in the meantime:

• if you pass -o "qt/*:essential_modules=False" and are using a configuration that matches our CI, you should get the same binaries that we currently have published
• pass -o "qt/*:essential_modules=True" and --build=missing

It really does depend on what your needs are with regards to the components that qt should have been built with

@ABBAPOH , @glennaycock - this is being fixed in https://github.com/conan-io/conan-center-index/pull/24876

[jcar87]

Should be fixed with the most recent recipe revision (might take ~20 minutes to be published).

[ABBAPOH]

I'll try take a look tonight, thanks!

[ABBAPOH]

Works for me now, thanks!
