When exploring unrecognized commandlineoption 039 arch039 did you mean, it's essential to consider various aspects and implications. unrecognizedcommand-lineoption '-arch'; did you mean '-march='?. I found that CMake will set -arch arm64 by default, and there is an option controlling the argument to -arch called CMAKE_OSX_ARCHITECTURES. However, setting this argument to false does not help since CMake still applies a default value of arm64 which is the architecture of the build host. x86_64-apple-darwin: unrecognized command line option ‘-arch’. Instead of -arch x86-64, the argument should be -march=x86-64 for darwin target (-march instead of -arch as key-value parameter and Apple target is dashed x86-64 instead of x86_64).
If there's some way to override or work around this, then I'd happily go for that until this issue can be fixed. How to remove -arch flag from arm-none-eabi-gcc in macos builds. How do you remove this flag? Additionally, i get this error: arm-none-eabi-gcc: error: unrecognized command-line option ‘-arch’; did you mean ‘-march=’?
(I see that pico-sdk compiles somehow remove this flag. This perspective suggests that, there has to be some settable parameter. I looked but nothing obvious stood out.) ben.boeckel (Ben Boeckel (Kitware)) February 8, 2023, 4:24pm 2 arm-none-eabi-gcc test project failed - JetBrains. Remove your arm-gcc toolchain from Preferences | Build, Execution, Deployment | Toolchains, so that there is only the "Default" toolchain.
Create a CMake toolchain file (for example, gcc-arm-toolchain.cmake). Apple: ARM GCC toolchain (arm-none-eabi-gcc) on Apple Silicon (M1) - GitLab. It's important to note that, the ARM GCC toolchain, a version of GCC used for embedded development, does not support the -arch option that many other compilers support.
On Apple M1 chips, CMake automatically appends the -arch flag to the "Checking for working C/C++ compiler" step of the build process. Additionally, [SOLVED] gcc: error: unrecognized command line option '-V' / Newbie .... It's also a current version, so I'm going to guess you have everything up to date (meaning you run pacman -Syu and not just pick certain packages to update). The only question, then is if you have the entire base-devel group installed. A more deterministic way of pointing to the exact toolchain you want to use is to provide its full prefix when setting CROSS_COMPILE.
This will avoid possible path-related errors, and the information on which exact toolchain was used for building will be embedded in your build script. -march=, -mcpu=, and -mtune= | MaskRay. Equally important, in GCC and Clang, there are three major options specifying the architecture and microarchitecture the generated code can run on. The general semantics are described below, but each target machine may assign different semantics. gcc - Error C++ compiling Ubuntu 20.04 LTS - Ask Ubuntu.
