[Mrtrix-discussion] Mac OS build error

[Michael Schirner]

Hi,

it seems like the clang compiler shipped with newer versions of XCode is
too restrictive and doesn't allow variable length arrays of non-POD
element type.
Upon running ./build I get the following messages:

STOP


Is there any workaround for that problem?

Thanks,
