Re: [isabelle] Isabelle on a Mac running linux

Hi Catherine

I had the same problem a few days ago. You need to change the file etc/settings so that in the first section (# Poly/ML 4.x/5.x (automated settings)) one of the options is the directory of Poly/ML; the automated settings are not correct. For instance, in my system, everything lives in /usr/local (i.e. Isabelle directory, ProofGeneral directory, Poly/ML directory are all in this folder), so I added the line


as one of the places it looks for ML_HOME. Then it should work fine. (NOTE I run my Mac under OSX, but I don't think it should make a difference, since it's the exact same error message I got)

Hi all,
I'm trying to install Isabelle on an Apple Powerbook running linux. I've got a working copy of Poly/ML from the polyml site, but when I run Isabelle I get the following:

Exception Io raised while writing to stdOut.
Unknown logic "HOL" -- no heap file found in:

When I try to build HOL I get the following error:

My Poly/ML version seems to be working fine, as I can use it separately from Isabelle. Has anyone else had this problem?

Thanks in advance!
