Aha! That's the missing piece.
Also, FWIW, apparently in Apple's latest OS "Mavericks", cpp does not support macro concatenation via ## like the true GNU compilers do. (I tested this; I copied and pasted example source from the GNU manual.) Furthermore it ignores the "--traditional" flag, i.e. generates no warning or error if you supply the flag, but it has no effect on the behavior.
So! Problem solved. The fix is to specify FPP= in the options file with the --traditional flag, using a true GNU compiler such as from MacPorts. No modifications to cctk_Types.h is necessary.
Thanks Roland!
Hi Scott,
We usually find that the apple compilers are not suitable for compiling the ET; we support using MacPorts using the simfactory optionlists, as this provides a single way to install all the required compilers and components. It's possible that we could make the apple compilers work, but there are other projects which have a higher priority.
