Comment (by dimpase):
I also noticed that some normaliz.lib functions are not working as
advertised, e.g.
{{{
> startNmz();
? open: Error for link _ of type: ASCII, mode: r, name:
nmz_sing_exec.path
? cannot read from `nmz_sing_exec.path`
? error occurred in or before normaliz.lib::startNmz line 292: `
string s=read(inf); `
? expected string-expression. type 'help string;'
? leaving normaliz.lib::startNmz
skipping text from `;` error at token `)`
}}}
instead of [http://www.singular.uni-
kl.de/Manual/latest/sing_1154.htm#SEC1230 this]. This is probably minor,
as {{{normaliz}}} executable is found in the {{{PATH}}}.
To make it work I can do
{{{
> setNmzDataPath("/tmp/");
> setNmzFilename("blah");
> writeNmzPaths();
> startNmz();
nmz_exec_path not set
nmz_data_path is /tmp/
}}}
If I then try the Singular input as above to compute
{{{intclMonIdeal(I)}}} I can see that the files {{{/tmp/blah.*}}} created
do not make sense. E.g. {{{/tmp/blah.in}}} is as follows:
{{{
1
1
2
3
}}}
which makes little sense.
I would not be surprised is this is an upstream (i.e. {{{normaliz}}}) bug.
