aarch64 compile error

[jenkin233]

Hello, An error occurred when cross compiling with ARCH = aarch64 , the error message says: aarch64/fenv.c:40:29: error: invalid initializer const fenv_t __fe_dfl_env = 0; how can i solve it?

I suspect this is no longer an issue, since we have binaries for aarch64:

https://github.com/JuliaMath/OpenlibmBuilder/releases

Please reopen with detailed instructions on compiler version, OS, and other details if still an issue.

Still an issue:

errors with

Oddly, this does NOT happen for our linux aarch64 cross-compile. Only MacOS cross-compile.

Maybe something to do with SDK, etc.?

[ngam]

And, one more piece of info: Compiles totally fine natively (on mac arm64).

+build_alias=x86_64-apple-darwin13.4.0
+host_alias=arm64-apple-darwin20.0.0

When building natively, build_alias will be arm64-apple-darwin20.0.0

[ngam]

As @isuruf fixed it in https://github.com/conda-forge/openlibm-feedstock/pull/29/commits/f83e0bae83c4245e11c76e54e77905e5ed85d101, this seems to resolve this particular problem for osx: sed -i.bak "s/CC = clang/CC ?= clang/g" Make.inc
