I notice that the Mac Homebrew installation refers to gcc46 - but there seems to be a problem running that on a Mac (it seemed to install OK under home-brew but I get segmentation fault 11- doing gcc-46 —version) :googling this, clang (Apple's LLVM-based C compiler) is intended to be a compatible replacement for gcc? I also tried gcc49 but that gives a problem with linking. If I use the clang compiler, I get a problem with the unknown type

Hi,

I am a new user trying to install the simplified demo on a Mac running OSX10.12 (Sierra)

I followed the instructions on https://docs.einsteintoolkit.org/et-docs/Simplified_Tutorial_for_New_Users and followed the instructions,

but when I run the command

./simfactory/bin/sim build --mdbkey make 'make -j4' --thornlist=manifest/einsteintoolkit.th

I at first get CST error 1:
-> Configuration script for thorn PTHREADS returned exit code 1
Error message: 'Did not find PTHREADS’

I am not sure where to set the PTHREADS_DIR or what to set it to- I also tried editing einsteintoolkit.th and disabling pthreads and Watchdog but then I get a error

unknown type name
'CCTK_REAL8'

Can anyone help?

Many thanks

Guy
