[question] wxWidgets requires gtk2-devel even gtk3-devel is installed

[kmreisi]

What is your question?

Hi all,

We use SLES 12 as build environment and using wxWdigets fails.

Error:

package gtk2-devel is not installed

ERROR: gtk/system: Error in system_requirements() method, line 45
zypper.install([f"gtk{self.options.version}-devel"], update=True, check=True)

ConanException: System requirements: 'gtk2-devel' are missing but can't install because tools.system.package_manager:mode is 'check'.Please update packages manually or set 'tools.system.package_manager:mode' to 'install' in the [conf] section of the profile, or in the command line using '-c tools.system.package_manager:mode=install'

Shouldn't the recipe detect hat gtk3-devel is available and use this automatically?

These are the packages we install:

        xz \
        xz-devel \
        zlib-devel && \
    zypper -n clean -a

Is there a way / option to force the usage of gtk3 in our conanfile.py

We have switched to use GTK2... I think it would be still cool to add an option to use wxWidgets with GTK3 from conan but since there is no activity at all and there is no need from my side anymore => closed ;-)
