Missing xgboost/lib/libxgboost.so #6

Closed dennismphil closed 6 years ago

dennismphil commented 6 years ago

Following the README#development,

If I 

$ git clone --recursive https://github.com/mljs/xgboost
$ cd xgboost
$ npm install                     // (Would be nice to include this also in the Development Section)
$ npm run build

gives the following error:

Important line I read was:

ERROR:root:xgboost/lib/libxgboost.so: No such file or directory ("xgboost/lib/libxgboost.so" was expected to be an input file, based on the commandline arguments provided)

When I checked the repo, it is missing the lib directory. A mention of https://github.com/dmlc/xgboost/blob/master/doc/build.md would be good to be included.
