pcre problems
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
config.log gives me:

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
OK~/Downloads/R-devel pcretest -C PCRE version 8.41 2017-07-05 Compiled with 8-bit support UTF-8 support No Unicode properties support No just-in-time compiler support Newline sequence is LF \R matches all Unicode newlines Internal link size = 2 POSIX malloc threshold = 10 Parentheses nest limit = 250 Default match limit = 10000000 Default recursion depth limit = 10000000 Match recursion uses stack OK~/Downloads/R-devel But ./configure gives me this: [snip] checking for pcre.h... yes checking pcre/pcre.h usability... no checking pcre/pcre.h presence... no checking for pcre/pcre.h... no checking if PCRE version >= 8.20, < 10.0 and has UTF-8 support... no checking whether PCRE support suffices... configure: error: pcre >= 8.20 library and headers are required OK~/Downloads/R-devel can anyone advise? hankin.robin at gmail.com
