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

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 

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
