OSX compile error

[3s3s]

When I follow this instruction https://github.com/monero-project/monero-gui#building-on-os-x
I have this error : "clang: error: the clang compiler does not support '-march=x86-64'"

More logs from terminal:

How can this be fixed?

Do you have a M1 Mac?

Do you have a M1 Mac?

Seems yes.
Mac OS Big Sur

Chip Apple M1

It did help, there is a different issue now. You also have to apply monero-project/monero@1ac7134 inside the monero submodule.

Delete this line and do the other explained steps in this issue, then it will compile fine: https://github.com/monero-project/monero-gui/blob/master/CMakeLists.txt#L27

Confirmed myself on a M1 Mac.

Next Monero GUI release (v0.17.3.0) will have proper support for M1, then you will only have to enter make.
