Make of mlpack does not generate libmlpack.so about mlpack HOT 4 CLOSED

Thanks Ryan ! Now, it makes sense :)

mlpack has been header-only since the 4.0.0 release, so there won't be any libmlpack.so generated. 👍

Then why is cmake and make required. There are header only libraries like enum.h which does not require such build

You are right, you can just directly include the mlpack headers without using cmake. But there are a handful of reasons why we have a build system:

• mlpack is more than just a header-only C++ library; it also has bindings to other languages that build libraries and executables
• CMake checks to ensure that all dependencies of mlpack (that's Armadillo, cereal, and optionally stb) are available on the system, which is a convenience to the user
• optionally, CMake can also download any missing dependencies
• configuring mlpack ensures that the version output is fully correct; if it is an unreleased git revision, the reported version will be the git commit hash after configuration
