vsamy / eigen-cddlib Goto Github PK

Hi Vincent,

Me and Arnaud found 1 + 1 issues with the cmake:

1. C++ 11 compilation option:

~/local/eigen-cddlib$ git diff

 option(BUILD_TESTING "Build unit tests." ON)

2. old version of Boost

leads to a different location of the file floating_point_comparison.hpp

We ignored the test using ccmake and compiled it.

Maybe we need an update of the CMakeLists.txt ?

Best,

Yuquan

Hi Vincent!

I noticed an interesting issue recently. Following the test example, I wrapped eigen-cddlib's Polyhedron object in a function: vRepComdCone. It worked fine if I call the function once. As long as I try to call vRepComdCone consecutively, I got the following memory error:

For completeness, I also attached the function I made:

Hi,
I already installed eigen3 and when I cmake it says it found my eigen

I would appreciate if you could help me :)

     void initializeMatrixPtr(Eigen::Index rows, Eigen::Index cols, bool isFromGenerators);

My version of Eigen is 3.2.10.

I have a question related to PR #5: is it really best to throw exceptions upon conversion errors?

In my use case, the exception was silently handled by an outer program, and it took me a lot of time to find that a global failure was due to a call I made to eigen-cddlib. I wouldn't mind one of the following alternatives:

• Outputting warnings to stdout/stderr
• Have set*() functions return bool instead of void

These sound to me safer/softer than throwing exceptions (which kill everything on their way if not properly caught).
