cmd/go: undefined symbols when linking using 'go get' with Anaconda C toolchain on Darwin #29597
Comments
I just tried running the command and wasn't able to reproduce the error. @bcmills would you mind checking out the issue? |
I'm also unable to reproduce the error (on macOS 10.12, which is the newest version I have readily available). From the error message, something may be wrong with your Xcode installation. Could you try removing and reinstalling
|
tried to remove Xcode and reinstalled it but the same error occurred: go get github.com/kovetskiy/zabbixctl runtime/cgold: warning: ignoring file /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/lib/libSystem.tbd, file was built for unsupported file format ( 0x2D 0x2D 0x2D 0x20 0x21 0x74 0x61 0x70 0x69 0x2D 0x74 0x62 0x64 0x2D 0x76 0x33 ) which is not the architecture being linked (x86_64): /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/lib/libSystem.tbd go env: go env |

I found the problem. There was another clang installation in my anaconda3 folder. Once I reinstalled it everything worked fine. thank you all :) |
@Chrisedeluxe Thanks! I recently installed Anaconda for another project, switched back to my Go project, which was now exhibiting this same behavior. You saved me a ton of time because I am sure I would have wasted a lot of time trying to figure this out. Thanks again! |
Could you be a bit more prescriptive about the steps you took here? I tried copying a different clang (from /usr/bin) and it didn't work. Thanks. |
It would also be helpful for me to hear what was done to resolve the problem. I'm also having these issues, and can't even run |
I have the same issue, where I recently installed Anaconda. Can you provide the specific steps you took to correct the problem? |
I found this question: This pointed me toward my .bash_profile to see the following added by Anaconda:
I commented this out, and my Go builds work again. This is a temporary fix, but gets me back on my merry Go dev way for now. |
note. i also had to restore $CC back to a proper value to resolve this. Anaconda is setting it to x86_64-apple-darwin13.4.0-clang |
