ld: unknown option: --start-group was supposed to come from ld in apple clang do not support this option.

Did you set USE_BLAS to mkl? USE_BLAS=mkl would introduce this linker flag in mshadow here. On mac, you can set USE_BLAS=apple instead as a workaround.

@apache/mxnet-committers: This issue has been inactive for the past 90 days. It has no label and needs triage.

For general "how-to" questions, our user forum (and Chinese version) is a good place to get help.

[lightingghost]

@szha Sorry I missed your response. I have already submitted a pull request to mshadow, adding os check to allow mkl be used on macOS

[azai91]

@lightingghost is this issue resolved? if so, we can close this issue.

[lightingghost]

@azai91 I have submitted a pull request to solve this problem to mshadow. But the request has not been accepted.

[azai91]

I see that there's s merge conflict with the PR. can you resolve that and then message @tqchen or @piiswrong about merging.

[lightingghost]

@azai91 I have updated that PR. @tqchen @piiswrong, would you please take a look?

[bgawrych]

@lightingghost Would you like to open PR in this repository? I still can reproduce issue, however currently cmake is main build tool - in case of no response I will ask someone to close this issue

[szha]

@bgawrych we moved away from makefiles and I don't think the change would be required anymore.
