Hi all, I'm running on a MacBook Pro with M1 chip (apple silicon) with MacOS Big Sur 11.2. I built my own clang/llvm v18.1.8 from source and it's setup to build both ARM64 and x86-64. The compiler successfully creates "fat" mac binaries which contain both the arm64 and x64 binaries for other open source projects, as well as my own code. I accomplish this by passing "-arch x86_64 -arch arm64" to the relevant compiler flags (CFLAGS for the open source projects). I'm trying to do the same for OpenSSL v1.1.1w, but I get the following error: crypto/arm_arch.h:55:6: error: "unsupported ARM architecture" Even if I try to build OpenSSL only for x64 (by passing CFLAGS=-arch x86_64), the OpenSSL compile sets both "-arch arm64 -arch x86_64". Note the order of these params is the opposite from what I pass, so tells me something in the configuration script is setting these. If I pass no params for CFLAGS, OpenSSL builds successfully, but for only ARM64. If this issue is already fixed in a newer version of OpenSSL I'm fine to upgrade. Thanks in advance!
