Hello, Jonas. > Thanks, I've added them to svn. I cursorily tested them and they at > least work under Mac OS X/x86_64 and Mac OS X/PowerPC.
Is it possible to test them under other platforms? SPARC, ARM, PowerPC64? I am testing full set of ALGLIB units under Win32/Win64/Lin32/Lin64 (x86). After all will be finished, I'll send you new test suite. However, there is a problem you should know about. ALGLIB uses non-deterministic unit tests. I.e. test sets are generated randomly (instead of being built-in, pre-generated). This approach have both benefits and drawbacks. From the one side, it allows me to test ALGLIB with much wider set of data (each time test is run, new inputs are tested). From the other side, there is a problem of false positives - test tolerances may be too stringent and sometimes correctly working unit don't match this stringent criterion. So error message from ALGLIB unit tests may means that: a. there is a bug in ALGLIB b. there is a bug in compiler c. there are no bugs, just too stringent criterion in unit test, which sometimes (0.1% of time, for example) doesn't met. In case (c) I relax error criterion used. But each case of this kind requires careful investigation. It is almost impossible to get rid of type (c) errors because numerical algorithms are very complex. Some ALGLIB units are more prone to such false alarms, some units are less prone. FFT units I've sent you are the most stable in this respect - false alarms are almost impossible. So we have two options: 1. to use only the most stable units 2. to give me limited access to SVN so I may run these tests myself and study their results. I have enough time on my hands so I can help you with tests if you want.
