Build failed in OSX

[pepedocs]

Replicate: Build by following the instructions in building from source.

• Install libraries

mkdir build cd build cmake .. make -j8

Expected: Build should pass.

Observed: Build failed.

Thanks for reporting. I'll look into this.

@pepedocs Hi, I have made Etaler buildable on OS X again

Please install tbb, cmake, gcc, cereal, catch2 from homebrew

Then by using the commands

git clone https://github.com/etaler/Etaler --recursive
cd Etaler
mkdir build
cd build
cmake -DCMAKE_CXX_COMPILER=g++9 ..
make -j4

Somehow compiling using clang causes linker errors. I'm still investigating that. But you should now able to have Etaler running.

Ok thanks @marty1885 - I will try these changes.

First error I've encountered by the way, I don't think this will affect Etaler core functionality though.

Ok I was able to build even with the errors above. There was a typo in the CMakeLists.txt file line:24. After this I tried building stackedsp.cpp but I got more errors.

I'm replying on the move. Pardon the quick explanation.

Seems your compiler is working in C++98/03 mode. May you provide your compiler version? Also the error message looks like one generated by clang, may you try GCC 9?
