If you are posting to ask for help with installing OpenMx, please understand that it is difficult for anyone to help you out if you don't provide a few key pieces of information! We therefore ask that your post include, at minimum, the following:
- Your operating system and architecture (e.g., "x86_64 Linux").
- The version of R you're running.
- A description of what goes wrong when you attempt installation, including the actual text of any warning or error messages you might encounter.
A simple way of providing #1 and #2 above is to simply include the output of OpenMx's mxVersion() in your post.
Thanks in advance!

What seems to be happening is that
omxGetNPSOL()is trying to find a directory in our software repository that matches what R reports your platform to be, 'big-sur-arm64'. The problem is, we don't have such a directory, because we've never built NPSOL for macOS running on 64-bit ARM. You could try manually downloading the x86_64 macOS build of the most recent OpenMx release from here, and try installing it as a local .tgz file. But, that will only work if you have installed the Rosetta 2 compatibility layer (which lets you run Mac programs compiled for x86_64 on Apple's M1). And even then, it will probably only work if your installation of R was also compiled for x86_64. I don't know for sure--I'm not a Mac user.You're the first person to ask us about using NPSOL on this new platform. I don't know when we'll have an M1-compatible macOS binary of NPSOL.
NPSOL seems to be "called" when I use the miFunctions.R set of functions created by Hermine. If, instead, I paste the relevant functions into the program code instead of calling the whole document [e.g., commenting out #source("miFunctions.R")] then the program runs - now I have start value problems, but it appears the code is running.
Hi Debbie!
Comment out the
mxOption(NULL, "Default optimizer", "NPSOL")line(s) from within the miFunctions.R file. Everything else might work then, including starting values.
