[Rd] Compilation error for R 4.0.2

[Wim R. Cardoen]

Hello,

I experienced a compiler error when I tried to compile the latest version
of R i.e. R4.0.2
making iosupport.d from iosupport.c
making lapack.d from lapack.c
making list.d from list.c
making localecharset.d from localecharset.c
grep.c(74): catastrophic error: cannot open source file "pcre2.h"
  # include<pcre2.h>
(The pcre2.h header file is actually present!)


I used the following compiler flags:
# PCRE2:
# -----
setenv CC gcc
setenv CFLAGS " -O2 -fPIC "
./configure --prefix=/uufs/chpc.utah.edu/sys/installdir/pcre2/10.35 \
            --enable-pcre2-16 --enable-pcre2-32 --with-pic

module purge
module load intel/2019.5.281

# USe a modern version of curl & pcre2 (The current one on Centos 7 is TOO
old)
setenv CURLDIR "/uufs/chpc.utah.edu/sys/installdir/curl/7.65.3"
setenv PCRE2DIR "/uufs/chpc.utah.edu/sys/installdir/pcre2/10.35"

setenv PATH ${PCRE2DIR}/bin:$PATH

 Setting Compiler & linker flags:
setenv CC icc
setenv CXX icpc
setenv F77 ifort
setenv FC ifort
setenv CFLAGS   " -axCORE-AVX512,CORE-AVX2,AVX,SSE4.2 -O3 -qopenmp

setenv CXXFLAGS " ${CFLAGS} "
setenv FFLAGS   " ${CFLAGS} "
setenv FCFLAGS  " ${CFLAGS} "
setenv LDFLAGS  " -Wl,-rpath=${MKLROOT}/lib/intel64_lin

--with-ICU --with-pic --with-x --with-lapack --with-pcre2

I also appended the corresponding config.log:

Thank you,
