我遇到了这个错误:“SSE 指令集未启用”。我怎么能弄清楚这个?
我有ACER i7,Ubuntu 11.10,请问有人可以帮助我吗?
任何帮助将不胜感激!
也在运行:
sudo cat /proc/cpuinfo | grep flags
给出:
flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clfl

实际上我试图安装gazebo-1.0.0-RC2-x86_64,并得到这个错误。

我的 cmakefile 中已经有了这个选项
if (SSE3_FOUND)
set (CMAKE_C_FLAGS_ALL "${CMAKE_C_FLAGS_ALL} -msse3")
endif()
if (SSSE3_FOUND)
set (CMAKE_C_FLAGS_ALL "${CMAKE_C_FLAGS_ALL} -mssse3")
endif()

set (CMAKE_C_FLAGS_ALL "${CMAKE_C_FLAGS_ALL} -msse4.1")
