[Users] Cactus Building Issue

[Rodriguez, Shanshan]

Hi Roland and Steve,

Thank you so much for your prompt reply! I’m compiling it on Mac OS X Mojave. I installed the latest version of Xcode and MacPorts a few days ago and had run the most recent updates. I checked my osx-macports.cfg and it does seem to require gcc-mp-7 (see below). But how do I find out what version of gcc I have in my MacPorts so I can edit them or if my compiler even exists?

Best wishes,
Shanshan


VERSION = osx-macports-2018-02-05


# Apple's compiler (Clang) does not support OpenMP, so we use GCC instead.

CPP = cpp-mp-7

FPP = cpp-mp-7

CC  = gcc-mp-7

CXX = g++-mp-7

F90 = gfortran-mp-7


CPPFLAGS =

FPPFLAGS = -traditional

CFLAGS   = -g -std=c11

CXXFLAGS = -g -std=c++14

F90FLAGS = -g -m128bit-long-double -fcray-pointer -ffixed-line-length-none

It says your compiler doesn't exist. Are you compiling on ios? What happens when you type "which gcc-mp-7"?

Hello Shanshan Rodriguez,

based on the fact that the code complains about gcc-mp-7 you seem to be
trying to compile Cactus on a mac using macports. Macports
periodically updates its gcc packages and quite likely the current one
is gcc-8 in which case the compiler is called gcc-mp-8 g++-mp-8 and
gfortran-mp-8.

You should modify the option list that you are using to reflect this.
In the tutorial this is the file osx-macports.cfg which you can find in
the simfactory/mdb/optionlists/osx-macports.cfg file.

I have also just made the required change to the release version
simfactory files.

Yours,
Roland

Hello,

I’m a new user of ETK and trying to follow the tutorial to set up Cactus. I ran into this problem building Cactus and hope you could help me resolve it. Here is the commend I’m stuck at:

%cd $cactus_dir
!time ./simfactory/bin/sim build -j2 --thornlist=thornlists/einsteintoolkit.th<http://einsteintoolkit.th><http://einsteintoolkit.th>

Where I got an error message at the end:


checking whether the C compiler (gcc-mp-7 -g -std=c11 -lgfortran) works... no
configure: error: installation or configuration problem: C compiler cannot create executables (see configs/<configname>/config-data/config.log for details).

Error reconfiguring sim-config
make: *** [sim-config] Error 2


I’m attaching the config, log file here. Could you suggest what I should do to fix this? Thank you so much!!


Best,
Shanshan Rodriguez
