Required https://aur.archlinux.org/packages/libgfortran6/ to build properly. gcc-Version 7.1.1 20170516 (GCC) mlpack 2.2.2-1

I tried building again (on another machine) and it did not get involved in this error. I doubt that it might be environment dependent. I would suggest you report this issue to the mainstream with machine details (OS, CPU, etc) for further help.

I build again, successed, looks like this bug can not reproduce.

Running 582 test cases... /tmp/yaourt-tmp-versus/aur-mlpack/src/mlpack-2.0.1/src/mlpack/tests/hoeffding_tree_test.cpp(991): fatal error: in "HoeffdingTreeTest/BatchTrainingTest": critical check batchCorrect > streamCorrect has failed [9914 <= 9914] I guess it's the library's bug. For now I simply disabled test execution in PKGBUILD.

To versusvoid: I've uploaded a patch for this issue. Please notify me if it still failed to build the package.

To versusvoid: After I apply the patch, I found it builds and passes with warnings with gcc 5.3.0. What error message did you encounter?

versusvoid commented on 2016-04-11 13:24 (UTC)

Build fails on gcc 5.3.0. This commit (https://github.com/mlpack/mlpack/commit/c751e61c8e37360c93b664597c189fb984f32de2) fixes the building, yet test fails anyway.
