发帖数: 439 | 1 .so文件是怎么用的? 下面是我的make过程显示:
CC -O3 -64 -mips4 -I../include Driver.o Setup.o -lm -lcomplib.sgimath
-lcomplex -lmf1 -L../ -lmetis -L../lib/ -o mf1.out
ld64: WARNING 84 : /usr/lib64/mips4/libm.so is not used for resolving
any symbol.
这个警告错误是怎么回事? 怎么解决?
另外一个问题:
程序用32位编译还好好的,换成64位编译后,一个不为零的double却变成零了.怎
么回事?
谢谢! |

发帖数: 8 | 3 I have F77 codes. On SGI Indigo2 R10000,
the comilation option in makefile is -O -mips4.
It ran very well.
But when I move to SUN blade2000,
I use comilation option:
-fast -xprefetch -xtarget=ultra3 -xchip=ultra3 -fns=yes -fsimple=2
it could pass compilation and generate excutable file. but when I run
it, it always show the fowlling info at the end:
Note: IEEE floating-point exception flags raised:
Inexact; Underflow;
Nonstandard floating-point mode enabled
