我安装了xmlsec，当我尝试validationXML文档时，它一直给我一个错误。

幸运的是，解决方法不是太糟糕。 要么在正常的位置创build符号链接（我通常不build议这样做），要么创build一个目录并将符号链接放在那里，然后使用LD_LIBRARY_PATH指向那里。 （我不知道为什么你的环境中已经设置了LD_LIBRARY_PATH，除非这是一个debugging尝试。）
# rpm -ql xmlsec1-openssl /usr/lib64/libxmlsec1-openssl.so.1 /usr/lib64/libxmlsec1-openssl.so.1.2.16
正如我从strace输出中看到的那样

xmlsec1-openssl查找libxmlsec1-openssl.so，而不是libxmlsec1-openssl.so.1。 你可以尝试去做
# cd /usr/lib64/ # ln -s libxmlsec1-openssl.so.1 libxmlsec1-openssl.so
