#854 fixed issues with EHRHARTPOLYNOMIALCOEFF ren anonymous
Description

I have downloaded version 4-1-2 to use the command above.

I started the example /Manual/4-0-2/sing_2286.htm and input every command as in the example.

The command LIB"polymake.lib"; indicated issues with gfanlib.so

The command polytope p = polytopeViaPoints(M); produced the error

? polytope is undefined

? error occurred in or before STDIN line 3: polytope p = polytopeViaPoints(M);

Can you please help fix this issue?

#852 fixed ""(1..2); gives segment fault somebody steenpass
Description

Here is a good candidate for the shortest input that causes a segment fault in Singular:

> ""(1..2);
Singular : signal 11 (v: 4122):
current line:>>""(1..2);<<
Segment fault/Bus error occurred at 28 because of 10283 (r:1566377906)
please inform the authors
trying to restart...

Of course this is not supposed to work, but it should be giving an error message rather than causing a segment fault.

#849 fixed Installation problems with 4.1.2 somebody frank.luebeck@…
Description

I wanted to upgrade Singular from 4.1.0 to 4.1.2 and ran into several problems:

  • The user and permissions for most files in the archive

ftp://jim.mathematik.uni-kl.de/pub/Math/Singular/UNIX/Singular-4.1.2-x86_64.tar.gz

are strange. When unpacked for a system wide installation then most users cannot read/use most files because of 640 permissions. Also the hint to use 'chmod' in your trouble-shooting paragraph is not correct. I did

chmod -R o+r . chown -R nobody.nogroup *

inside the unpacked directory (which could be done before packing the archive).

  • When trying to use the help I get an error message saying that an index file share/singular/singular.idx is missing (it is there in 4.1.0).
  • The following input worked with 4.1.0:

ring R = 2,(x,y),rp; ideal I = [x, x+y];

but not with 4.1.2. Removing the []'s seems to solve the problem. But why is there such a syntax change in a minor upgrade?
