在R中安装RNetCDF软件包时无法访问udunitslib

Question

您好我正在尝试在RStudio中安装RNetCDF软件包。但是，当我尝试这样做时，我收到错误消息

-----Error: libudunits2.a not found-----
     If the udunits2 library is installed in a non-standard location,
     use --configure-args='--with-udunits2-lib=/usr/local/lib' for example,
     or --configure-args='--with-udunits2-include=/usr/include/udunits2'
     replacing paths with appropriate values for your installation.

然后我尝试了

install.packages('udunits2', configure.args=('--with-udunits2-lib=/opt/lib'))

因为我的libudunits2.a位于/opt/lib

错误信息再次相同;还有

checking udunits2.h usability... no
checking udunits2.h presence... no
checking for udunits2.h... no
checking for ut_read_xml in -ludunits2... no

我再次尝试给出了udunits.h的位置

install.packages('udunits2', configure.args=('--with-udunits2-lib=/opt/lib/ --with-udunits2-include=/opt/include'))

这次错误是：

checking for ut_read_xml in -ludunits2... no

我正在使用Fedora 23.任何帮助都将非常感激。谢谢
