Unable to install XML package in R on CentOS
You have two problems clearly stated in the output:
- The first is a warning, you may want to remove
a.out/
:
checking for C compiler default output file name... rm: cannot remove 'a.out.dSYM': Is a directory a.out checking whether the C compiler works... yes
- The second is an error and your dealbreaker -- you do not have libxml2-dev (or whatever CentOS calls this) installed:
checking for xml2-config... no Cannot find xml2-config
Without the XML development tools provided by libxml2-dev
you simply cannot build the package from source.
