Another solution could be to add the option -m128bit-long-double to all of CFLAGS, CXXFLAGS, F77FLAGS, and F90FLAGS.

Do you need real*16 for your work? Otherwise it would be easiest to just not use this type. For Cactus itself, you can use either of the options
REAL16_KIND = 10
or
DISABLE_REAL16 = yes
to choose what you want to do. Do either of these options help?

Hi,
I found on the web that x86-64 CPUs do not support require 16-bytes precision, and gfortran 4.5 supports only up to kind=10. I compiled just fine using ifort on another x86-64, but it seems that the intel compilers can do this in software. The new gfortran 4.6 would support a quad precision in software. Was anybody successful in compiling on a x86-64 with GNU compilers?
best, Maria

Hello,
I have problems compiling einsteintoolkit on Ubuntu 10.10 with gnu 4.4 or 4.5 compilers. The errors are:
