R XML package on RHEL

Hi

Thanks for your reply. I do have them installed it seems:

[dasneved at drdsv01zatcrh ~]$ yum list installed | grep xml2
*Note* Red Hat Network repositories are not listed below. You must run this command as root to access RHN repositories.
libxml2.x86_64       2.7.6-21.el6_8.1  @RHEL6.8-Server-P1-Jul2016-x86_64        
libxml2-devel.x86_64 2.7.6-21.el6_8.1  @RHEL6.8-Server-P1-Oct2016-x86_64

I have a .so for ldap on the server, maybe I should try symlinking to it? I can't find anything called libldap without a version number, so maybe that is the problem?

[dasneved at drdsv01zatcrh ~]$ find / -name '*libldap*' 2>/dev/null

As far as I know you only need libxml and libxml2-devel. Do you have those installed?

Hi

I am trying install the XML package on R 3.3.0 on RHEL. After it complained that the curl library was missing and we installed it, it continues to fail the linking step:

gcc -m64 -std=gnu99 -shared -L/usr/lib64/R/lib -ldl -lpthread -lc -lrt 
-lcurl -lidn -lssh2 -lssh2 -lssl -lcrypto -lssl -lcrypto -lgssapi_krb5 
-lkrb5 -lk5crypto -lcom_err -lldap -lz -lrt -o XML.so DocParse.o 
EventParse.o ExpatParse.o HTMLParse.o NodeGC.o RSDTD.o RUtils.o 
Rcatalog.o Utils.o XMLEventParse.o XMLHashTree.o XMLTree.o fixNS.o 
libxmlFeatures.o schema.o xmlsecurity.o xpath.o -lxml2 -lz -lm -lz 
-lxml2 -L/usr/lib64/R/lib -lR
/usr/bin/ld: cannot find -lldap

It is not clear which package is meant to provide the ldap library, although I can see I library that may be appropriate it is not referred to as libldap as such. Should I be creating a symbolic link to the library or something like that?

Please help!
