R devtools fails while installing xml2

Question

I have R 3.2.0 in RHEL 5.

I try to install devtools

install.packages("devtools", dep=TRUE)

At the end it fails with the error

xml2_url.cpp: In function cpp::List url_parse(Rcpp::CharacterVector):
xml2_url.cpp:85: error: struct _xmlURI has no member named query_raw
xml2_url.cpp:85: error: struct _xmlURI has no member named query_raw
make: *** [xml2_url.o] Error 1
ERROR: compilation failed for package xml2

How do I fix this issue? It seems to be a version problem?

AND RAN THE yum install libxml2 libxslt

Answer 2

I have similar kind of problems with installing "xml2" on new R environment. Here is a solution that fixed my problem:

withr::with_makevars(c(CXX = "g++ -std=c++11"), 
   install.packages("xml2", verbose = TRUE))
