我遇到这个错误的麻烦：“SSE指令集未启用”.我怎么能弄清楚呢？
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 on pebs bts xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 x2apic popcnt xsave avx lahf_lm 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()
