########## File path: docs/install/build_from_source.md ########## @@ -180,6 +180,8 @@ More information on turning these features on or off are found in the following There is a configuration file for make, [`make/config.mk`](https://github.com/apache/incubator-mxnet/blob/master/make/config.mk), that contains all the compilation options. You can edit it and then run `make` or `cmake`. `cmake` is recommended for building MXNet (and is required to build with MKLDNN), however you may use `make` instead. For building with Java/Scala/Clojure, only `make` is supported. +**NOTE:** When certain set of build flags are set, MXNet archive increases to more than 4 GB. Since MXNet uses archive internally archive runs into a bug ("File Truncated": [bugreport](https://sourceware.org/bugzilla/show_bug.cgi?id=14625)) for archives greater than 4 GB. Please use ar version 2.27 or greater to overcome this bug. Please see https://github.com/apache/incubator-mxnet/issues/15084 for more details. Review comment: Is there a way to detect this case so users are not faced with a strange error message but specifically prompted to upgrade ar? I'm afraid that users might not see this specific part of our documentation and just get frustrated. If our build pipeline would automatically notify them (ideally ahead of time or) after the error occured, that would be beneficial to the user experience. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
