/usr/local/bin/xmllint：编译webkitgtk-2.46.3时未定义的符号：xmlMemSize

Question

在编译最新稳定版本 webkitgtk-2.46.3 期间，我收到此错误：

rapy@raohy:~/下载/webkitgtk-2.46.3$ cmake --build builddir/

[ 92%] Built target WebCore_CopyPrivateHeaders
[ 92%] Built target WebKit-forwarding-headers
[ 92%] Generating ../../WebKitGTK/DerivedSources   
/ModernMediaControlsGResourceBundle.c,     ../../WebKitGTK/DerivedSources 
/ModernMediaControlsGResourceBundle.c.deps
 /usr/local/bin/xmllint: symbol lookup error: /usr/local/bin/xmllint: undefined symbol: xmlMemSize
/home/raphy/Downloads/webkitgtk-2.46.3/builddir/WebKitGTK/DerivedSources    /ModernMediaControlsGResourceBundle.xml: Child process exited with code 127.

但是检测到合适的 xml2 库：

raphy@raohy:~/Downloads$ tar -xf webkitgtk-2.46.3.tar.xz
raphy@raohy:~/Downloads$ cd webkitgtk-2.46.3/
raphy@raohy:~/Downloads/webkitgtk-2.46.3$

raphy@raohy:~/Downloads/webkitgtk-2.46.3$ cmake -B builddir -DPORT=GTK    
-DUSE_GSTREAMER_WEBRTC=TRUE -DENABLE_WEB_RTC=ON -DUSE_GTK4=OFF

libxml2

libxml2-dev

libxml2-utils

安装的已经是最新版本了:

raphy@raohy:~$ sudo apt-get install libxml2 libxml2-dev libxml2-utils

libxml2 is already the newest version (2.9.14+dfsg-1.3ubuntu3).
libxml2-dev is already the newest version (2.9.14+dfsg-1.3ubuntu3).
libxml2-utils is already the newest version (2.9.14+dfsg-1.3ubuntu3).

操作系统：Ubuntu 24.04

我错过了什么？如何让它发挥作用？

Answer 1

Ubuntu libxml2-utils 软件包在

/usr/bin/

上安装 xmllint，如
所示

dpkg -L libxml2-utils | grep 'xmllint'

但构建是从

/usr/local/bin.

中挑选它

可能存在版本不匹配的情况。参见

/usr/local/bin/xmllint --version
