I am trying to do a build and local install of R 4.0.4 on Red Hat Linux 6.8. There were several unmet dependencies which I resolved by doing local installations (following the procedure in this). However, I couldn't resolve the issue of pcre2 with that procedure. This is the configure command I run:

./configure --with-pcre2 --prefix=$HOME/bin/R-4.0.4 --enable-R-shlib LDFLAGS="-L/$HOME/local/zlib-1.2.11/lib -L/$HOME/local/bzip2-1.0.8/lib -L/$HOME/local/xz-5.2.5/lib -L/$HOME/local/pcre2-10.00/lib" CPPFLAGS="-I/$HOME/local/zlib-1.2.11/include"

This is the error I get:

checking whether PCRE support suffices... no
configure: error: PCRE2 library and headers are required, or use --with-pcre1 and PCRE >= 8.32 with UTF-8 support

I also tried configure with a local installation of pcre-8.44 and --with-pcre1 flag but I get the same error.

What should I do so that the configure script detects the pcre2 local installation?


I had the same issue and resolved it by installing the "pcre2-devel" package. I had pcre and pcre-devel packages, which worked for R 3.x as well as the pcre2 package, but the required "pcre2-devel" wasn't installed by default.

    Thanks, can you please tell me how to install the pcre2-devel package? I couldn't find any source for that. Is it included in pcre2 source? – Dronacharya Mar 6 at 5:35
  • I only had to run "yum install pcre2-devel" but it's present in the "rhel-7-server-optional-rpms" repository on my machine. I'm not sure what the repository for RHEL 6.8 is but you could review the repositories in /etc/yum.repos.d/redhat.repo and set "enabled=true" for the optional RPMS repository. You may want to shoot in the dark and try "yum install --enable-repo=rhel-6-server-optional-rpms pcre2-devel" – Teague Sterling Mar 8 at 17:08
  • The only problem is I don't have sudo permissions. That's why I was doing local installs of the dependencies. Do you have any other suggestions? – Dronacharya Mar 10 at 6:40
