Since today, I have a problem compiling ONVIF in C++ using GSOAP library.
It seems to be due to a 404 error on the webpage https://www.w3.org/2004/08/xop/include which is referenced in the onvif.xsd specification (here: https://www.onvif.org/ver10/schema/onvif.xsd)
<xs:import namespace="http://www.w3.org/2004/08/xop/include" schemaLocation="http://www.w3.org/2004/08/xop/include"/>
For those who need the content, it can be found here: https://web.archive.org/web/20220513081836/https://www.w3.org/2004/08/xop/include
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://www.w3.org/2004/08/xop/include"
targetNamespace="http://www.w3.org/2004/08/xop/include">
<xs:element name="Include" type="tns:Include"/>
<xs:complexType name="Include">
<xs:sequence>
<xs:any namespace="##other" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
<xs:attribute name="href" type="xs:anyURI" use="required"/>
<xs:anyAttribute namespace="##other"/>
</xs:complexType>
</xs:schema>
does anyone has a patch for this ? can Onvif people publish a fix ?
Note: w3 website documentation also refers to this 404 page : https://www.w3.org/TR/xop10/#xop_include
I think this is a normal occurrence, and happens to me at least a couple times a month. To resolve this I downloaded the schema sheets down and then changed the "schemaLocation" to the local path/file name for the schema sheet.
I would download down all of the xsd, wsdl, and included files to a local directory then they won't need to be fetched on compilation. I was able to access the xop/include at the link now so it must be online again, but I would cache it locally to save yourself a headache in the future when it goes down again.
