Getting a floating point error when running the example

[luillo (Luigi Salvatore Esposito)]

Hello @khalil.alkhour,

Could you confirm your Xcode or CLT version using these commands?

pkgutil --pkg-info=com.apple.pkg.CLTools_Executables

xcodebuild -version

From version 16 onwards, there is a known issue in the linker. If this is the case, you can refer to this solution:

Illegal instruction Error on macOS Sequoia

Dear @Obada , We’ve identified that this issue is related to the new linker introduced in the latest CLT. To get FLUKA running again, please try the following temporary fix: Open the FLUKA makefile, which you can find in the src directory of your FLUKA installation (<path to FLUKA>/src/makefile) Add -ld_classic option to the linker rules for the FLUKA executables. You’ll need to add it in two places: At line 43: ${FC} -ld_classic -o $@ ${LFLAGS} -L${LIBPATH} ${LIB} and similarly at…

Please let us know if this helps.

Best, Luigi
