This is a self-installing binary for Windows from the _unstable_ branch of PARI/GP (2.2.7-alpha). [5.2MB archive, 13.1MB installed] Features of this test release include : 1) PDF manuals: user's manual, tutorial, reference card [ ... Acrobat Reader not included ... ] 2) full online help ( gphelp ) Try out ??sin, ???sin ???"elliptic curves"@ ??readline ??tutorial ??refcard ?? Note: you need Acrobat Reader installed for the last 3. 3) Readline line-editing facilities, including command history and contextual completion. Try out and the cursor keys. 4) prettyprinter ( tex2mail ) Try \o3 before typing some (simple) commands, e.g sin(x) 5) "galdata" support files, required by polgalois() in degree > 7 Try polgalois(x^8 - 2) 6) High-resolution plot: ploth() and friends should work now. Try ploth(x = 0, 10, sin(x)), and try to resize the window. 7) install() should work, at least to import private symbols from the library Try install(addii, GG); addii(2,3) =========================================================================== The installer sets 1) Start Menu entry 2) Desktop link [ ... no dedicated icon yet ... ] 3) uninstall support (via Start Menu or Windows Add/Remove) =========================================================================== Please test as much as you can! And report bugs, preferably to pari-dev (or possibly pari-users), if something does not work as expected. Compared to the previous binaries, I have tried to fix a number of problems with the online help, which did not work on most installations. I have also upgraded my build system which fixes all the internal bugs which were reported ( in particular, SEGVs during any MPQS factorization ). Remaining problem: 1) Hitting Ctrl-C or Ctrl-Break to abort a computation only works once. I have no clue about this one. All feedback will be much appreciated ! Have fun, Karim. -- Karim Belabas Tel: (+33) (0)1 69 15 57 48 Dép. de Mathématiques, Bât. 425 Fax: (+33) (0)1 69 15 60 19 Université Paris-Sud http://www.math.u-psud.fr/~belabas/ F-91405 Orsay (France) http://pari.math.u-bordeaux.fr/ [PARI/GP]
