build errors

[harmn]

I got some errors using the suggested build command:

$ g++ -std=c++11 ../src/**/*.cpp -o mx
../src/compute/mx_sum.cpp:158:46: error: ‘log’ is not a member of ‘std’; did you mean ‘clog’?
  158 |                         data[pidx][0] = std::log(data[pidx][0]);
 ../src/compute/mx_sum.cpp:158:46: error: ‘log’ is not a member of ‘std’; did you mean ‘clog’?
  158 |                         data[pidx][0] = std::log(data[pidx][0]);
      |                                              ^~~
      |                                              clog
../src/extract/mx_extract.cpp: In function ‘void mx_extract_file(MX_opt&)’:
../src/extract/mx_extract.cpp:205:21: error: ‘pow’ is not a member of ‘std’
  205 |     size_t N = std::pow(2, 10); // 1024
      |                     ^~~
../src/extract/mx_extract.cpp: In function ‘void mx_extract_index(MX_opt&)’:
../src/extract/mx_extract.cpp:311:21: error: ‘pow’ is not a member of ‘std’
  311 |     size_t N = std::pow(2, 10); // 1024

These were fixed by adding #include <cmath> to Common.hpp

And then I got a couple of linker errors involving functions defined in Common.cpp. To fix these I added ../src/*.cpp to the build command: g++ -std=c++11 ../src/*.cpp ../src/**/*.cpp -o mx

For compiling Common.cpp, I also needed to add #include <cmath> in that file.

Hi! Thank you for your issue. I have updated the README.md to include installation instructions. We originally started to write mx in cpp but decided to continue development in python.
