|Updating an old C program which uses parilib|
ee = smallinitell(lisGEN(stdin)); where stdin contains [0,1,0,4,4] for example.There seems to be no exact replacement for this function so I am using scanf to read the five coefficients as longs and then using mkvecn to package the coefficients into a vector.
scanf("%ld %ld %ld %ld %ld",&c1,&c2,&c3,&c4,&c5); printf("%ld %ld %ld %ld %ld \n",c1,c2,c3,c4,c5); eee=mkvecn(5,(GEN)c1,(GEN)c2,(GEN)c3,(GEN)c4,(GEN)c5); ee = smallinitell(eee); Where ee and eee are defined as GEN. The printed result is 0 1 0 4 4 *** segmentation fault: bug in PARI or calling program. *** Error in the PARI system. End of program. 1) Is there an exact replacement for lisGEN? 2) Am I doing something stupid?In previous variations to solve this problem I have encountered stack overflow and an 'undefined' gzero.
3) Where did gzero go? Any help would be greatly appreciated. Best regards, Jack Fearnley
