Re: Subsets_of_k broken?

There seems indeed to be a bug in it. I'll look into it. But if you replace the explicit constructor with the function call all_subsets_of_k(s,2) your code will work fine.

Re: Problems generating documentation

Probably you are missing the pre-installed DTDs for XHTML. In Ubuntu, they are packaged under the name w3c-dtd-xhtml.

Looks like bugs, especially the second one. Could you please create Trac tickets?

Re: Polymake & OpenMP

Actually, alias handlers are not active in read-only access mode, they are only used for tracking of mutable aliases like matrix minors. What indeed may change anytime are the reference counters of the data instances. Surely we can modify them with atomic operations, but it would incur quite some ov...

Re: HilbertBasis of a Cone<Rational>

Works pretty fine now. Maybe you want to change your Error message, so one can see that he has to install software. Unfortunately, it's not trivial. polymake works with a set of production rules; some of, being dependent on external software, are automatically disabled if the required software is n...

Re: Bug in polymake 2.10

Unit tests are not private, they are just too many to be bundled together with a source distribution. Surely we ought to publish them, it would just incur some additional administrative overhead, e.g. they also need to be branched off with each public release, and we are so short on HR... The final ...

Re: Bug in polymake 2.10

Thanks again for the numerous fixes! I've incorporated them all in the current codebase, except for changes in the configuration script. We should first thoroughly check if polymake compiled with clang correctly executes all testcases, how the automatic wrapper compilation works, etc. before we reco...

Re: Bug in polymake 2.10

You are absolutely right regarding ListValueOutput::operator<<, its definition is indeed misplaced. But I couldn't localize any references to the protected iterators of sparse_proxy outside of these classes. Could you please point me to them? Regarding "secret" code repository: if you are ...

Re: Bug in polymake 2.10

Thanks a lot for pointing to all these bugs! Indeed, they remained undiscovered by gcc, because they sat in a code written "for the stock", which was never instantiated so far. The fixes will appear in the next release. All identifiers starting with an underscore and a capital letter have ...
