Compiling on Centos 7.8 (gcc 4.8.5)

[ihayhurst]

Compilation on Centos 7.8 (gcc 4.8.5) failed initially with errors like:

In file included from ../include/iwstring.h:32:0,
                 from IWString_class.cc:32:
../include/iwaray.h:155:61: error: expected ‘,’ or ‘...’ before ‘&&’ token
     resizable_array_p<T> & operator = (resizable_array_p<T> &&);
                                                                                                 ^

To resolve:
I was able to compile successfully by pre-pending -std=c++11 to the CXXFLAGS line on the Makefiles
/Lilly-Medchem-Rules/supporting_libraries/Makefile
/Lilly-Medchem-Rules/Molecules/Makefile

Issue 2 (Compiling on Debian) includes a report about a successful compilation with CentOS 7 (gcc 4.8.2) after some adjustments. Despite its age (posted back in 2015), does this resolve your problem? I'm not familiar how program packages are managed by CentOS, but according to a search here CentOS 8 offers a more recent release of gcc 8.3.1 suggesting an update could resolve the issue, too. A third option may be a Docker container; with file README_Docker.md Ian provides guidelines how to set up and eventually use the program.

As by today, I found no problem compiling the program and running the executable in Linux Debian 10 (bullseye / branch testing) with gcc (10.2.0), make (gnu make 4.3), and ruby (2.7.1.p83).
