Hello Suo-Ning Wang,

hmm, actually looking at the paths in your error message, this is not a personal Ubuntu based laptop, is it? Instead this looks like some share university system where you yourself cannot install cmake.

If the system offers “environment modules” (module list / module load) then you can try and see if there is a cmake module available (or, if the system is small enough, the sysadmin may be willing to install a copy of cmake).

If that is not possible then you have to compile your own cmake. The easiest way is actually using the EinsteinToolkit where there is a “branch” that provides cmake. To do so please run (in the same directory where you first ran `GetComponents`):

./GetComponents --no-update https://bitbucket.org/einsteintoolkit/manifest/raw/a3d645186fc84f605ede2103a6f56ae99fc8c939/einsteintoolkit.th

and after that remove your partially compiled code

rm -rf Cactus/configs/sim

then compile again using sim build as shown in the tutorial.
