System: Red Hat Enterprise Linux Server release 6.5 (Santiago) I?ve installed zlib 1.2.11 on the home folder of a Red Hat HPC as part of the process for installing R base 3.4.0. I get this error even after successful install of zlib checking for inflateInit2_ in -lz... no checking whether zlib support suffices... configure: error: zlib library and headers are required I?ve checked R documentation and configure file for the issue of R requiring version newer than 1.2.6 but not lexicographically recognizing 1.2.11 as >1.2.6, and that particular bug was patched in 3.4. Any suggestion and/or input would be much appreciated. Regards, Bashir [[alternative HTML version deleted]]
