有用simplescalar的朋友吗？找不到 stdio.h
本帖最后由 wait_rabbit 于 2011-11-04 02:42 编辑下了四个压缩包，simpleutils-2v0.tgz，simpletools-2v0.tgz，simplesim-3v0e.tgz，gcc-2.7.2.3.ss.tar.gz。
经过一番修改，测试显示是编译成功了的。# ./sim-safe tests-pisa/bin.little/test-math

sim-safe: This simulator implements a functional simulator.This
functional simulator is the simplest, most user-friendly simulator in the
simplescalar tool set.Unlike sim-fast, this functional simulator checks
for all instruction errors, and the implementation is crafted for clarity
rather than speed.

请朋友们释疑，谢谢！ 打印版本也是正常的，不知到究竟是哪里出了问题。# ./sslittle-na-sstrix-gcc -v
Reading specs from /home/SimpleScalar/lib/gcc-lib/sslittle-na-sstrix/2.7.2.3/specs
gcc version 2.7.2.3
指定主机的 /usr/include 就能用了。哎，不知道是哪一步的编译出了点问题。暂且这么用着吧。
