The OpenSees Community

The Mac version is now updated and up.

Hi Yumeng,

This is an old post, but perhaps this answer can help someone in the future. The error you are getting is because your compiler cannot find the `libsuperlu.a` library. OpenSees depends on several libraries, e.g., solvers, graph partitioners, etc. These libraries must be built or installed independently before OpenSeesPy can be compiled. Many of these can be installed via the home-brew package manager. For example, by running: Depending on your build configuration, the full list of required libraries can be found in the `OpenSeesLibs.pri` file. After you have installed the required libraries on your computer, you need to go back into the OpenSeesLibs.pri file and change the paths so that they point to the locations of the libraries on your computer. After that it should find the libraries and compile.

OpenSeesPy for Mac is now updated (3.2.2.10) and it should run on Big Sur.
