OK thanks Tomas, but I get

OK~

It seems you need to enable source code  repositories on your system
(and then run apt-get update).
You can enable them in /etc/apt/sources.list, uncomment all lines
starting with deb-src.

thanks for this guys.

I only compiled pcre myself as a last resort,  because of the
./configure failure.  But AFAICS  apt-get reports correct
installation:

OK~/Downloads/R-devel sudo apt-get install r-base-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
r-base-dev is already the newest version (3.5.2-1cosmic).
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
OK~/Downloads/R-devel

I would just run this

apt-get build-dep r-base

that will install all packages needed to _build_ r-base, so including PCRE.

Hi there, ubuntu 18.04.2, trying to compile R-devel  3.6.0,  svn 76155.

I am having difficulty compiling R. I think I have pcre installed correctly:

You can use

apt-get build-dep r-base

to install binary Ubuntu packages needed to build R from source,
including PCRE, so there should be no need to compile PCRE from source.
If you need for some special reason to compile PCRE from source, please
see R Admin Manual, section A.1 on how to configure PCRE. The manual
also says how to set compilation flags for R to look for headers in
other directories. Sometimes it helps to search the config.log when
configure fails. If still in trouble, please report how you built PCRE
and how you told R where to find it, and the relevant part of
config.log, to maximize chances people could offer useful advice.

Best,
Tomas

can anyone advise?
