17:04 CoCoA-5 Support #1258 (Closed): Manual page for CantStop
- @CantStop.cpkg5@ now works. There should be a manual page at least for @PlayCantStop@.
Perhaps some of the other fn... -

-
- I have now updated the .C files too. Everything compiles and runs.
It is possible that I have missed some 0 (that w...

- I have done the header files. There may still be one or zeroes which escaped me (but I hope not). Next are the .C f...
-
- From C++11 there is the constant *@nullptr@* for the null pointer.
Update our (C++) code to use it!
-
- Here are the aspects to be addressed next:
* how to serialize rings (_i.e._ follow previous format, but passing ring... -
- Anna has cleaned the file so that it is syntactically OK.
Now we must look at the semantics. -
- Current state:
* *@NumTheory.C@*
* *@NumTheory-ContFrac.C@*
* *@NumTheory-CoprimeFactorBasis.C@*
* *@NumTheory-pr... -
- I prefer to defer this question until later, until when we have decided what exactly @exgcd@ should do (and whether i...

- Anna uses @clang@ on MacOS, while I use @g++@ on Linux.
We get different outputs for @test-output@: its seems that t... -
- In @test-output@ Anna and I get different outputs (due to different RingIDs) because we use different platforms.
I... -
- I have changed the @configure@ script so that it prints out a clearer summary.
I have changed the @Makefile@ so that... -
- Anna prefers the longer field names. Code cleaned, and checked-in. Anna will test.
Doc updated.
-
- I have updated the CoCoA-5 manual.
I have modified the code so that @OpenSocket@ returns a record with 4 fields: *...

16:40 CoCoA-5 Bug #545: Compiler g++ 4.2.1 (clang-503.0.40) on MacOSX 10.9: warnings and errors
- Problem with PIE (#3) resurfaced because of a line swap in configure.
Just in case it happens again:
this was solve...

- Done and partly tested.

-
- Fixed.
Now, *guaranteed* computes GBasis if missing, so result is guaranteed.
Testing.

* revised @configure@ scr... -

- The CoCoA-5 test file @test-ApproxSolve.cocoa5@ calls the function @ShapeLemma@, but this function is not in the CoCo...

- Checked in. Documentation. Tested. Works on Anna's computer.
Closing.
-
- As for zero-dimensional ideals, implement it so we can pass it to CoCoA-5.
-
- JAA notes that the product of zero factors should return a list containing 1 element which is a 0-tuple (namely, the ...

- In terms of compilation speed, it is probably not necessary to split @NumTheory.C@; my computer compiled the current ...
-
- This has been "resolved" for 5 months. Moving to "feedback". Hope to close while I'm in Genoa.
-
- Check that the new configuration system works on several different platforms (incl. Microsoft???)

- If we use C++11 then this is a relatively simple task (since C++11 already offers a decent "sleep function").

- Consider adding a "sleep function" to CoCoA-5.
This could be useful in an interactive context (_e.g._ the "Can't S...
