Make compilation error

[Morteza-M-Saber]

First of all thank you very much for developing Dawg and making it freely available. I am trying to install make on supercomputer running Red Hat. I installed boost 1.65.0 and Cmake version 3.9.4 for running " cmake .. -G 'Unix Makefiles'" and then running make. But I keep getting the following error:

I would appreciate if you could help figuring out what goes wrong.

What compiler and version are you using to compile Dawg? I suspect that you need to try something more recent than what is used by default on your Redhat machine.

I am using GNU Make 4.2.1 and GCC 6.1.0. Here is what I do in order:

1)Unzip DAWG and make a new directory inside named 'my_build' and cd into it 2)run Cmake .. -G 'Unix Makefiles' which returns -- The C compiler identification is GNU 4.4.7 -- The CXX compiler identification is GNU 4.4.7 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Found Git: /usr/bin/git (found version "1.7.1") -- version: 2.0.1-unknown. -- Looking for pthread.h -- Looking for pthread.h - found -- Looking for pthread_create -- Looking for pthread_create - not found -- Check if compiler accepts -pthread -- Check if compiler accepts -pthread - yes -- Found Threads: TRUE -- Boost version: 1.65.1 -- Found the following Boost libraries: -- program_options -- unit_test_framework -- Boost library: /home/masih/miniconda3/lib -- Boost headers: /home/masih/miniconda3/include -- Could NOT find TESTU01 (missing: TESTU01_LIBRARY TESTU01_INCLUDE_DIR) -- Configuring done -- Generating done -- Build files have been written to: /home/masih/Baterial_simulator/DAWG/dawg-develop/my_build 3)Run make which gives the above-mentioned error.

Everything run without problem except for the final step. Everything seems to be in their latest version!

You are going to need to use at least GCC 4.8.2 to get the development branch to compile as it uses C++11 features. You can change which compiler CMake uses by default by setting the CXX and CC environmental variables.

Thanks. That solved the problem.
