Hi,

I am trying the official example https://github.com/platformio/platformio-examples/tree/develop/unit-testing/calculator

I'm using macOS Catalina 10.15.7, and my gcc version is:

➜  calculator git:(develop) gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 11.0.3 (clang-1103.0.32.62)
Target: x86_64-apple-darwin19.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Any suggestion is more than welcome. Thank you!

I am using the latest pio and native.

➜  calculator git:(develop) pio --version
PlatformIO Core, version 5.0.4

➜  calculator git:(develop) pio platform install "native"
Platform Manager: native @ 1.1.3 is already installed
The platform 'native' has been successfully installed!
The rest of the packages will be installed later depending on your build environment.

Are you using ar and ranlib from Apple as well? I had GNU versions of these tools, which caused the same problem. See also https://community.platformio.org/t/native-desktop-unit-testing-on-macos/20416 Making sure that the Apple versions of ar and ranlib are used, and then

rm -rf .pio/build
pio test

helped in my case.

Making sure that the Apple versions of ar and ranlib are used?

how do we make sure it uses ar instead of gcc? Where can we configure that?

ivankravets commented 2 years ago

Please upgrade to the latest PIO Core via pio upgrade --dev. Should be fixed.

lrascao commented 2 years ago

FYI, i'm on PlatformIO Core, version 6.1.3 on MacOS and also ran into this, only after changing PATH to use /usr/bin/ar and/usr/bin/ranlib does the error go away

platformio / platform-native
