Unusual workaround required to get Ada programs to build on an M1 Mac running macOS Tahoe 26.3.1

Hey, yes, known issue:

GNAT toolchain now broken after OS upgrade to MacOS 26 (Tahoe), arm64

Thanks! For a reference, using a Fish shell, this solved the problem: set -gx SDKROOT “$(xcrun --sdk macosx --show-sdk-path)” set -gx LD_LIBRARY_PATH “$SDKROOT/usr/lib” set -gx LDFLAGS “-L$SDKROOT/usr/lib” set -gx LIBRARY_PATH “$SDKROOT/usr/lib”
