3. Page 2 of 4 Research Update gcc 4.1.0 compatibility progress (1) Fixed the SysComplex and Integral conflict problem and make Checksum compiling (2) Got System and IO library passed gcc4.1.0 "make", "make test", and "make install“ (3) Solved "variable not declared in this scope" problem in Math/Scalar (4) Solved gcc4.1.0 "converting loses 1" problem (with optimization -O2 open). (5) "Specifying the whole class" works with Testing_Prototype_1, but not with ISIP_IFC

4. Page 3 of 4 Research Update gcc 4.1.0 compatibility progress (6) "inline" solution solved "duplicated definition" error during "make", but isn't suitable to ISIP_IFC (7) Got Math/Scalar library passed "make" by applying "#ifdef ISIP_TEMPLATE_*_*" to all template specifications (8) Testing_Prototype_2 (independent from ISIP_IFC) simulated "make test" and re-produced "duplicated definition" error. (9) Daniel suggested to move template specifications into corresponding derived classes. This worked with Testing_Prototype_2. (10) Added simple version of MVector and VectorDouble classes into Testing_Prototype_2, VectorDouble got correct result.

5. Page 4 of 4 Research Update Plans Add more functions and features into VectorDouble and test it again Add simple matrix classes into Testing_Prototype_2 and do the test Continue working on mailing list Communicate with Michael, make ISIP_IFC document accessible through web
