Subject: [PATCH] Fix build with libxml2 2.12
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

||
libxml2 2.12.0 made `xmlGetLastError()` return `const` pointer:
|
||
|
||
https://gitlab.gnome.org/GNOME/libxml2/-/commit/61034116d0a3c8b295c6137956adc3ae55720711
|
||
|
||
Clang 16 does not like this:
|
||
|
||
error: assigning to 'xmlErrorPtr' (aka '_xmlError *') from 'const xmlError *' (aka 'const _xmlError *') discards qualifiers
|
||
error: cannot initialize a variable of type 'xmlErrorPtr' (aka '_xmlError *') with an rvalue of type 'const xmlError *' (aka 'const _xmlError *')
|
||
|
||
Let’s update the variables to `const`.
|
||
For older versions, it will be automatically converted.
|
||
|
||
But then `xmlResetError(xmlError*)` will not like the `const` pointer:
|
||
|
||
error: no matching function for call to 'xmlResetError'
|
||
note: candidate function not viable: 1st argument ('const xmlError *' (aka 'const _xmlError *')) would lose const qualifier
|
||
|
||
Let’s replace it with `xmlResetLastError()`.
|
||
|
||
ALso remove `LIBXMLDOC::Xerr` protected member property.
|
||
It was introduced in 65b0e5455b547a3d574fa77b34cce23ae3bea0a0
|
||
along with the `xmlResetError` calls.
|
||
It does not appear to be used for anything.
