rotate_left() in ex.h => compilation failure
by Alexei Sheplyakov 04 Mar '08

04 Mar '08

Hi! I've tried to compile a library using GiNaC (version 1.3) with GiNaC version 1.4. Compilation failed because ex.h defines `rotate_left' function: 55 /** Rotate bits of unsigned value by one bit to the left. 56 * This can be necesary if the user wants to define its own hashes. */ 57 inline unsigned rotate_left(unsigned n) 58 { 59 return (n & 0x80000000U) ? (n << 1 | 0x00000001U) : (n << 1); 60 } The library in question has a function static inline double rotate_left(double x, int i = 1) so the code like double x = rotate_left(5); fails to compile due to ambigously overloaded function. I think this is GiNaC's fault -- having such a helper function in a *public* header is not a good idea. So, I'd like to move it (say, to utils.h). Any objections? Best regards, Alexei -- All science is either physics or stamp collecting.

CLN 1.2.0 is available
by Richard B. Kreckel 19 Jan '08

19 Jan '08

Hi, CLN 1.2.0 has been released. Here is a list of what's changed: Algorithmic changes ------------------- * Save big amounts of memory in the computation of some functions and constants by: - Avoiding pre-computation of series terms and instead computing them in a streamed way. - Avoiding computation with excess precision in binary splitting algorithm by coercion of intermediate integer values to floating-point as early as possible. Implementation changes ---------------------- * Added support for huge numbers: - intC used for all counter loops. - intE is now a 64-bit type on all 64-bit platforms and even on selected 32-bit platforms. * CLN now uses C++ exceptions for error handling. The cl_abort() hook is not supported any more. Please refer to the documentation to learn about existing exception types. * Fixed a bug on i386 where comparing Z/2Z ring zeros returnd random results. * Removed cl_boolean. Use built-in C++ bool instead. Other changes ------------- * Dropped the cln-config script. Please use pkg-config instead. * Updated infrastructure to that of libtool-1.5.24. * Changed encoding of all files to UTF-8. * Fix compilation issues with GCC-4.3. * Fix linking issues on platforms that don't feature weak symbols (like win32). CLN is available from <http://www.ginac.de/CLN/>. Cheers -richy. -- Richard B. Kreckel <http://www.ginac.de/~kreckel/>

Branch or HEAD?
by Richard B. Kreckel 13 Dec '07

13 Dec '07

Jens, Is GiNaC-1.4 branched already? I just tried to commit something to numeric.cpp in 1.4 and 1.5, and in 1.5 I got Up-to-date check failed for `numeric.cpp'. Both appear to refer to the same version. I'm confused because <http://www.ginac.de/Download.html> mentions the branch. Cheers -richy. PS: Unfortunately, git is not part of the Linux distribution running on www.ginac.de. I'ld have to compile it manually... :-( -- Richard B. Kreckel <http://www.ginac.de/~kreckel/>

migrating to git?

Dear GiNaC developers, On Tue, Nov 20, 2007 at 09:55:16PM +0100, Richard B. Kreckel wrote: > Anyway, the discussion how to proceed regarding the SCM should be > continued on ginac-devel.

SVN is not *that* bad, but still it is inconvenient (centralized, branching/merging is unnecessary difficult, no offline mode, etc). > Even with git, I think we should have an official reference repository > from which we make releases simply because this way users always know > where to get prereleases from. Sure. > I guess there's no way to convert the CVS history to git, is there? There is git-cvsimport utility. I use it to sync my git repository [1] with CVS. It happens to work surprisingly well, although there was a minor problem during the initial import [2]. So, we could either clone my repository (excluding -vargs branches), or do the conversion once again. [1] http://theor.jinr.ru/~varg/git/ginac Note: the repository is not browseable, use git to clone it. [2] Some *very* old files (auto* tools helpers) in the CVS are corrupted. This problem never get noticed (I guess nobody ever tried to checkout such an old version). I've edited the history a little bit to pretend those file never existed in the (CVS) repository. I don't think this is a problem, since such files should not be included into the repository in first place. Anyway, they were deleted 6 years ago, so who cares?
