Re: polymake on FreeBSD -- some questions and help needed

I have another question concerning the shared library: Right now, the port provides libpolymake.so.4.4 and libpolymake-apps-rt.so.4.4. What about libpolymake-apps.so.4.4? Should that one be provided, too? If so, I have to figure out why that one is not picked up by pkg. Sorry for the delay. That li...

Re: polymake on FreeBSD -- some questions and help needed

I don't really know how you ended up with these undefined symbol errors for libnormaliz but they should disappear when adding ' -lnauty ' in the correct place, either in the global ' LIBS ' variable passed to configure ( ./configure LIBS=-lnauty ) or by adding an appropriate check in the libnormaliz...

Re: polymake on FreeBSD -- some questions and help needed

Hi, I am currently working on bringing polymake into the FreeBSD ports system. It builds fine and the testsuite runs without errors. I am working with the polymake-4.4-minimal version. Thanks a lot for working on this and that is already a very good starting point. Because of problems with the respe...

Re: Segmentation fault when using Polymake in Julia

For updating the packages can you try running using Pkg; Pkg.update(); (Latest versions are Polymake.jl 0.5.5 and Oscar.jl 0.5.1.) For lldb, and also to test this in a clean environment it would be good to try this directly in the julia shell. So please run Base.julia_cmd() in your REPL. This should...

Re: Segmentation fault when using Polymake in Julia

Hi, it is rather hard to say what can be causing this, I have seen a similar error once or twice on our MacOS CI but it was not really reproducible. Can you please provide some more details on your configuration, i.e. versioninfo(); using Pkg; Pkg.status(); You can also try updating your packages (a...

Re: Example of rational polytope with Ehrhart polynomial

Hi, thanks for the report, when I tried it locally I got the following output: polytope > $m = new Matrix([1,0,0],[1,1/2,0],[1,0,1/2]); polytope > $p = new Polytope<Rational>(VERTICES=>$m); polytope > print join("\n",@{$p->EHRHART_QUASI_POLYNOMIAL}); 1/8*x^2 + 3/4*x + 1 1/8*x^2 + 1/2*x + 3...

Re: Checking if a polytope is a matroid polytope

It seems that your Apple command line tools are not working correctly, please run:

Code: Select all

xcode-select --install
You might need to do this every time you upgrade Mac OS X.

Re: Checking if a polytope is a matroid polytope

polymake: ERROR: C++/perl Interface module compilation failed; most likely due to a type mismatch. Set the variable $Polymake::User::Verbose::cpp to a positive value and repeat for more details. How can I fix this? Please try increasing the verbosity with: $Polymake::User::Verbose::cpp=3; Then reru...
