@jerry73204 - it compiled successfully, thanks!

Also, it still complains about armadillo>=6.500.0, that it cannot be found so I have to install it explicitly. Other than that it's great!

I update the package to 3.0.4 and disable check by default.

Mark please check if this update fixes your problem.

gcc: error: unrecognized command line option ‘-std=c++11-march=x86-64’ error: command 'gcc' failed with exit status 1 make[2]: *** [src/mlpack/methods/sparse_coding/CMakeFiles/build_pyx_sparse_coding.dir/build.make:58: src/mlpack/methods/sparse_coding/CMakeFiles/build_pyx_sparse_coding] Error 1

This is when installing it with trizen, first it complained armadillo>=6.500.0 cannot be found, but it went away after installing it manually.

Is this a typo in the makefile or? Should there be a whitespace between 11 and the dash?

to jerry73204,

Thank you, I'll just skip the check() step, but just saying that I have reproduced the issue around 10 times...

jerry73204 commented on 2018-05-12 18:16

To alcron33, My build runs successfully and I cannot reproduce this error. The message indicates that it was caused by a failing test. It's better to report it to upstream. If you need the build to be done, as a remedy, you can comment out check() function in PKGBUILD.

I have tried installing a couple of times... it always displays this error when doing the check() after build:

Running 1262 test cases... /tmp/yaourt-tmp-alcros33/aur-mlpack/src/mlpack-3.0.0/src/mlpack/tests/distribution_test.cpp(888): fatal error: in "DistributionTest/GammaDistributionRandomTest": difference{0.100615} between d2.Beta(i){1.1811578593978589} and b(i){1.3} exceeds 10%

To flying-sheep:
I drop the load_save_test.
If you still encounter problems during tests, feel free to modify the PKGBUILD file.

flying-sheep commented on 2017-09-20 16:30

hmm, i get the error mentioned in

/home/phil/.cache/pacaur/mlpack/src/mlpack-2.2.5/src/mlpack/tests/load_save_test.cpp(637): fatal error: in "LoadSaveTest/LoadHDF5Test": critical check test.n_rows == 4 has failed [2 != 4]

they say it can be safely ignored, but since the package doesn’t build without the tests passing, that isn’t helpful.

maybe include a patch that fixes/disables the test?

Required 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.
