[GiNaC-list] problems with cstring and string

[Tania Robens]

Hi

I have tried to implement the newest CLN version (cln-1.3.4) and ginac 
version (ginac-1.7.2). i am using gcc (GCC) 4.9.2 20150212 (Red Hat 
4.9.2-6) (but also had the same problem with newer compilers)

uname -a renders

Linux 2.6.32-642.11.1.el6.x86_64 #1 SMP Tue Nov 15 
14:13:21 CST 2016 x86_64 x86_64 x86_64 GNU/Linux


CLN works, but for ginac i get

and, when i ignore this and do make anyways, i have


In file included from 
/home/trobens/programs/cln/install/include/cln/string.h:9:0,
                  from

    using ::memchr;
            ^
/opt/rh/devtoolset-3/root/usr/include/c++/4.9.2/cstring:76:11: error: 
‘::memcmp’ has not been declared
    using ::memcmp;


...etc ... which then leads to a stop in the compilation.

i have tried various ways around this, if someone has a quick solution 
please let me know

the same mistake occurs with earlier ginac versions and, as stated, with 
newer gccs (up to 6.1)

??

Thanks Best Tania Robens
