Esp-idf: [TW#16749] linker failing on macOS (IDFGH-1619)

[matthewberryman]

I've followed the instructions here https://esp-idf.readthedocs.io/en/latest/get-started/macos-setup.html and http://esp-idf.readthedocs.io/en/latest/get-started/index.html#get-esp-idf making sure to recursively clone and also setting PATH and IDF_PATH variables (and restarting my shell to pick them up), but I get the following linker errors building the hello_world project. I've repeated the same steps (but with the linux build tools) on Ubuntu and not encountered this issue.

It looks like some compiler flags are being overridden from the environment. Could you please check if printenv | grep -i FLAGS contains any of LDFLAGS, CFLAGS, CPPFLAGS, CXXFLAGS?

[matthewberryman]

Ah, that's it. I had LDFLAGS being set separately through a really old shell startup script line I'd forgotten about. Problem solved, thanks!

[HarterHorst]

exact same error here. No results on printenv | grep -i FLAGS.

Any other ideas?

[matthewberryman]

Maybe you’ve got a LD_LIBRARY_PATH or other compiler / linker env var set?

Can't find anything in the environment. I have added the -v options to get more information from the compiler and structured the file a little bit. I have no idea what these files are and if the belong to the build environment of the esp-idf or not.

This also helped me a lot.
I did unset LDFLAGS and the other global environment vars, and it worked like a charm.
Thank you!

[rodrigoords]

Can you explain what exactly to do with this error? I have the same.
