Hi Ludo,


<= blockquote type=3D"cite">

I have noticed that the non-termination problem is not confined to the
opencascage_oce package. If I try=20

$ nix-instantiate --strict --eval --xml -A guile
/home/paul/.nix-defexpr/channels/nixpkgs

that does not terminate either.



Does it just take long, or does it simply not terminate?

After a few (approximately five) min= utes the process is still producing xml.  Looking at the output, after= killing the process, there is a large amount of blank space plus the occas= ional line of xml, such as:

<function column=3D= "15" line=3D"47" path=3D"/nix/store/k3jqgxqfwg6q9bgkys63c25lbjprl3gq-nixpkg= s-17.03pre96825.497e6d2/nixpkgs/lib/types.nix">



$ nix-instantiate --version
nix-instantiate (Nix) 1.11.2

For my nix installation:
<= br>
$ nix-instantiate --version
nix-instantiate (Nix) 1= .11.4

Also, I have cloned the nixpkgs repository s= o that I can change the version more easily.  To set the nixpkgs direc= tory to be the same version as the version you are using:

$ git checkout dde259d

Then I get the= same output:

$ export NIX_REMOTE=3Ddaemon
$ ./pre-inst-env guix import nix /data/paul/sourceCode/nixpkgs= opencascade_oce

;;; SSAX warning: Skipping PI: xm= l
