I am taking over a colleagues project. The project used to compile just fine, but now throws 256 errors and fails to compile. The two main errors are "ArmClang.exe: error: unsupported option '--config' ", and "ArmClang.exe: error: cannot specify -o when generating multiple output files ".
Could this be compiler related? Project used to use Arm Compiler 6.13, but I am using 6.07.
What is your environment? I don't know why you are using such an old compiler. FYI, the latest version is 6.16
The latter error, cannot specify -o when generating multiple output files should be self explanatory (and also occurs with the latest compiler).
The --config option is interesting. This is consumed by the latest compiler, but is not documented (as far as I can see)
