Hello, I am using the callable library and have two basic questions about the QuadraticExtension type. I create a QuadraticExtension object as follows: polymake::QuadraticExtension<polymake::Rational> q {1,2,3}; Is it correct that this corresponds to the element 1 + 2 sqrt(3) in Q(sqrt(3))? So if a ...

Thanks, Ewgenij, for your very detailed answer.

In the end I could not figure out what the problem was, everything seemed fine. So I just installed everything needed by Polymake locally and now it works.

Dear polymakers,

I am still stuck with my problem. Any ideas how to fix it? Do you need additional information about the system I'm using?

Thanks,
Moritz

Thanks, Benjamin, that already helped a great deal! Now Polymake compiles without any errors. However, when I start it it complains: Can't locate loadable object for module Polymake::Ext in @INC (@INC contains: /home/mws/polymake-2.15-beta3/share/polymake/perllib /home/mws/polymake-2.15-beta3/lib/po...

I need to install Polymake 2.15 on yet another system, and again problem occur. Let me first describe the system: Linux soroban 2.6.32-504.30.3.el6.x86_64 #1 SMP Tue Jul 14 11:18:03 CDT 2015 x86_64 x86_64 x86_64 GNU/Linux Perl: v5.10.1 (*) built for x86_64-linux-thread-multi GCC: 4.4.7 20120313 (Red...

Deleting /usr/local/share/polymake did the trick.

Thanks, Benjamin & Michael!

I compiled Polymake 2.14r1 from the source code available on polymake.org. The compilation finished without any errors (that's what it reported at least). As a C++ compiler I am using clang version 3.6.2. My perl version is perl 5, version 22, subversion 0 (v5.22.0). Perl did not change between the ...

I just downloaded Polymake 2.14r1 and installed it without any errors (so it seems at least) on my up-to-date Arch Linux system. When I try to start it I get the error message Loading applications now...polymake: ERROR: Corrupt or incomplete installation: shared module /usr/local/lib/polymake/bundle...

Yes, I am interested in changing the existing vector. So
keeps the first n elements and discards the rest?

I am using the callable library of Polymake 2.14. Let's say I define a vector of size 4 in my C++ program, i.e., polymake::Vector<Rational> vec {4}; After doing some computations I need to discard the last element. If vec would be of type std::vector, I'd just use .pop_back(), but this doesn't seem ...
