Goals
LinBox
At the Sage Days 6 coding spring:
- fix bug fallout from the 1.1.4 release (mostly done)
fix Blas:MatrixHom memleak
determine which workarounds can be discarded from Sage's LinBox wrapper library
Sage class that wraps LinBox matrices directly - this should simplify automated testing of LinBox via Sage
wrap solve and other interesting BlackBoxes
sort out gmpxx.h issues, i.e. NTL version detect is broken in LinBox 1.1.4, but not in Sage
- fix test-zero-one segfault on Solaris
merge LinBox wrapper library into driver's directory in Linbox, making the build simpler
Short term, i.e. plans for a potential 1.1.5 LinBox release in the next 3-4 weeks:
- support threaded GoToBLAS
support (threaded) SunPerfLib on Solaris
- print configuration also to stdout so that it is logged in the Sage build log
- investigate slow iterator test on OSX (10 or more times slow than under Linux on the same hardware)
- proper lround fix for Solaris via ACTEST
- set up build bots for Cygwin and Solaris, wider range of gcc releases (mabshoff)
add STLPort debug build target to general LinBox build
- add and review Paul's fixes for a) string copy in case of exception b) missing inlines
Givaro
- merge OSX 10.5 build fix by rpw
- improved gcc 4.3 buidl fix: instead of string.h include cstring
- merge fixes/improvements by malb from Sage's givaro.spkg:
-- 2007-02-03 Martin Albrecht <malb@...> * new upstream release: 3.2.6 * Changes to upstream (everything else below is irrelevant): ./src/library/poly1/givpoly1factor.h (2006-10-21 fix) ./src/kernel/zpz/givgfq.inl (2006-10-21 fix) ./src/kernel/zpz/givgfq.h (2006-10-21 fix) ./aclocal.m4 64-bit (2006-10-29 fix) ./src/library/poly1/givpoly1padic.h (2006-11-09 fix)
ATLAS
- build ATLAS with netlib's Lapack per default
- use sage_fortran as fortran compiler
- update to the 3.8.0 release, apply install-dynamic-libs patch
- build multi-threaded version of ATLAS on demand, too
