OSX: nim cpp -r torch.nim fails

[timotheecour]

after building ATEN via #5 (comment):

ATEN=/tmp/d11/Users/timothee/git_clone/nim/pytorch/built/output/lib nim cpp -r torch.nim

I suspect you are not using nightly branch.

Osx needs {.passC: "-std=c++14".} which is already in there.. (nightly)

[sinkingsugar]

btw you can now also try:

conda create -n nimtorch -c fragcolor nimtorch
source activate nimtorch
nim cpp -r ~/miniconda3/envs/nimtorch/dist/nimtorch/torch.nim

Replace ~/miniconda3/ with your conda location if different

[timotheecour]

thanks!

after brew cask install anaconda etc:

nim cpp -r ~/miniconda3/envs/nimtorch/dist/nimtorch/torch.nim

this worked:

nim cpp -o:/tmp/d03/app -r /Users/timothee/homebrew/anaconda3/envs/nimtorch/dist/nimtorch/torch.nim

[sinkingsugar]

Oh yeah true... -o is now needed 👍

[timotheecour]

what's simplest way to use custom nim? I like to use nim devel or a fork; whereas this uses latest stable (0.19)

[sinkingsugar]

https://github.com/fragcolor-xyz/nimtorch#semi-manual-way

This way you just use ATen binaries, nothing else ( you bring your nim etc )

[sinkingsugar]

Nice catch! our tests were not testing clang, gonna add that too 😄

[sinkingsugar]

Should be fixed now, could you try to force update your aten package? (has same version)

edit: actually this does not seem to work... let me see to bump version

[sinkingsugar]

Released 2018.10.10 now. Tested locally, seems fixed!

[timotheecour]

ATEN=/tmp/d11/Users/timothee/git_clone/nim/pytorch/built/output nim cpp -r -f -o:/tmp/z01 torch.nim now works, thanks!
(note: all i did was update nimtorch, I didn't even rebuild aten but seemed to work anyways)
