我正在尝试按照本指南将Xerces-C安装到我的Shibboleth 2 SP： https://wiki.shibboleth.net/confluence/display/SHIB2/NativeSPLinuxSourceBuild
但是当我跑步时：./configure --prefix=/opt/shibboleth-sp --disable-netaccessor-libcurl
我收到此警告：WARNING: unrecognized options: --disable-netaccessor-libcurl
[...]
config.status: creating src/xercesc/util/Xerces_autoconf_config.hpp

我尝试传递它make和make install但是没有安装它，我得到的结果如下：
make[2]: Nothing to be done for `install-data-am'.
make[2]: Leaving directory `/home/user/opt/xerces-c-3.1.1/samples'

test -z "/home/user/opt/shibboleth-sp/lib/pkgconfig" || /bin/mkdir -p "/home/user/opt/shibboleth-sp/lib/pkgconfig"

make[2]: Leaving directory `/home/user/opt/xerces-c-3.1.1'
make[1]: Leaving directory `/home/user/opt/xerces-c-3.1.1'
这是什么意思？
谢谢！
