Package libxml-2.0 was not found in the pkg-config search path
1、问题 Package libxml-2.0 was not found in the pkg-config search path
2、检查是否有库文件, no
root@PC1:/home/software# find / -name "libxml-2.0.pc"
root@PC1:/home/software# echo $PKG_CONFIG_PATH
这个变量啥也没有
3、尝试解决
root@PC1:/home/software# wget ftp://xmlsoft.org/libxml2/libxml2-2.9.2.tar.gz
root@PC1:/home/software# tar -xvf libxml2-2.9.2.tar.gz
root@PC1:/home/software# cd libxml2-2.9.2
root@PC1:/home/software/libxml2-2.9.2# ./configure --prefix=/usr --disable-static --with-history
root@PC1:/home/software/libxml2-2.9.2# make
root@PC1:/home/software/libxml2-2.9.2# make install
4、检查库文件,有了!
root@PC1:/home/software/libxml2-2.9.2# find / -name "libxml-2.0.pc" /home/software/libxml2-2.9.2/libxml-2.0.pc /usr/lib/pkgconfig/libxml-2.0.pc
root@PC1:/home/software/libxml2-2.9.2# echo $PKG_CONFIG_PATH
但是,这个环境变量还是空的, 暂且不管他。
5、测试, 貌似可以了
