Hi,

I'm trying to build a desktop app, that need to acces calendar informations from Evolution Data Server.

So, I tried to generate bindings for ECal-2.0.gir with java-gi, but it failed.

I'm using Asahi/Fedora 43 and java-gi:0.14.1.

With this command line (wich includes dependencies for ECal) :
java-gi -d org.gnome /usr/share/gir-1.0/Camel-1.2.gir /usr/share/gir-1.0/Json-1.0.gir /usr/share/gir-1.0/EDataServer-1.2.gir /usr/share/gir-1.0/ICalGLib-3.0.gir /usr/share/gir-1.0/ECal-2.0.gri

I get the following error :
not a valid name: Camel,camelError

Any idea about what's going wrong ?

Hi, thanks for trying out java-gi!

You can fix the error if you make a local copy of Camel-1.2.gir and update line 19. Change c:identifier-prefixes="Camel,camel" to c:identifier-prefixes="Camel". Java-GI doesn't expect multiple values here. I'll fix that in the next java-gi release, but at least this is a workaround.

To generate the bindings, you also need to include libxml2.gir.

I tried to compile the resulting bindings, but I'm afraid that there are multiple issues in the generated code. It should not be very hard to fix those manually. In most cases you can just delete the offending method.

Thanks :-)

I copied and updated Camel-1.2.gir.

However, I get another error when running this command line :

Yes, typo, "gri" should be "gir".
