c – SSE指令集未使能

我有ACER i7,Ubuntu 11.10,请任何人可以帮我吗？

任何帮助将不胜感激！

还运行：

sudo cat /proc/cpuinfo | grep flags

得到：

flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clfl
ush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx rdtscp lm constant_tsc arch_perfm

ida arat epb xsaveopt pln pts dts tpr_shadow vnmi flexpriority ept vpid

其实我是试图安装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()
if (SSE4_1_FOUND)
  set (CMAKE_C_FLAGS_ALL "${CMAKE_C_FLAGS_ALL} -msse4.1")
endif()
if (SSE4_2_FOUND)
  set (CMAKE_C_FLAGS_ALL "${CMAKE_C_FLAGS_ALL} -msse4.2")
endif()
