I finished build 1.2.0 on cygwin using gcc 3.2 20020927. All tests fail with segmentation faults and empty .out files. Retreating to 1.1.7, most tests succeed. The only failure is with archive, which I don't need. Here is the test output: ----------several historic failures: (no output) ----------consistency of numeric types: (no output) ----------power laws: (no output) ----------consistency of symbolic functions: (no output) ----------consistency of nestedsums functions: (no output) ----------symbolic differentiation: (no output) ----------polynomial GCD computation: (no output) ----------rational function normalization: (no output) ----------series expansion: (no output) ----------symbolic matrix manipulations: (no output) ----------linear solve: (no output) ----------indexed objects: (no output) ----------color objects: (no output) ----------clifford objects: (no output) ----------archiving system: archiving/unarchiving delta.([[-1,0,0],[0,Euler,0],[0,0,atan(y^(-1)*x==-15/17*I)]]*delta.($7).x)~(g~2~(log(cos((128.0)*y^(-1)*x^(-1))))*ONE*{x,-11*y,(acos(6-10*I))+(-(26/3725-48/3725*I)*sqrt(65+120*I))*(-3+5*I+x)+((17364/13875625-652/13875625*I)*sqrt(65+120*I))*(-3+5*I+x)^2+Order((-3+5*I+x)^3)})-(2.4275000000000002132)*eps~*0~y+((abs(y))+(D[0](abs)(y))*(-y+x)+(1/2*D[0,0](abs)(y))*(-y+x)^2+(1/6*D[0,0,0](abs)(y))*(-y+x)^3+Order((-y+x)^4))+42*y^sin(Catalan*y)*ONE*x*eps.(1/2*y).0.(FAIL)-x~(-mu).(1+2*y)*T.x*(gamma~mu*gamma.mu)*(-I*f.y.x.2+d.y.x.2) erroneously returned delta.([[-1,0,0],[0,Euler,0],[0,0,atan(y^(-1)*x==-15/17*I)]]*delta.($7).x)~(g~2~(log(cos((128.0)*y^(-1)*x^(-1))))*ONE*{x,-11*y,(acos(6-10*I))+(-(26/3725-48/3725*I)*sqrt(65+120*I))*(-3+5*I+x)+((17364/13875625-652/13875625*I)*sqrt(65+120*I))*(-3+5*I+x)^2+Order((-3+5*I+x)^3)})-(2.4275000000000002132)*eps~*0~y+((abs(y))+(D[0](abs)(y))*(-y+x)+(1/2*D[0,0](abs)(y))*(-y+x)^2+(1/6*D[0,0,0](abs)(y))*(-y+x)^3+Order((-y+x)^4))+42*y^sin(Catalan*y)*ONE*x*eps.(1/2*y).0.(FAIL)-x~(-mu).(1+2*y)*T.x*(gamma~mu*gamma.mu)*(-I*f.y.x.2+d.y.x.2) ----------hash maps: (no output) ----------miscellaneous other things: (no output) Paul Kienzle pkienzle@nist.gov
