Dear Sharareh Sayyad alps + Z2 symmetry need to compile the source. An installation note can be found in the following page.

Dear all,
I've been trying to run a code with Z2 symmetry. I've first installed ALPS by the Conda installer. The installation went well, and I was able to run test codes without the Z2 symmetry. But upon turning on this symmetry to try "mps_optim," I received
Exception thrown:
I don't know this symmetry group. Please, check your compilation flags. I've then found this issue on the GitHub [ https://github.com/conda-forge/alps-feedstock/issues/12 | https://github.com/conda-forge/alps-feedstock/issues/12 ] which seems to remain unresolved.
I've next attempted to run my code by ALPS installation using Mac ports. I was again successful in installing and running tests except for codes with Z2 symmetry which a similar exception is raised.
I've also checked for the possibility of source package installation and followed steps suggested in this old thread [ https://lists.phys.ethz.ch/pipermail/comp-phys-alps-users/2015/002815.html | https://lists.phys.ethz.ch/pipermail/comp-phys-alps-users/2015/002815.html ] While the "CMake" step went well in this attempt, I got numerous errors when running "make," and this step failed around 22% progress. I have tried to change my compiler by varying "CMAKE_CXX_FLAGS" but couldn't push the installation any further. I have attached the "CMakeCache.txt" for reference.
Do you have any suggestions on making changes on either Conda or Port installation so that my code with Z2 symmetry starts working?
Best regards, Sharareh Sayyad
