Question

我正在开发一个无人机项目，我的Raspberry Pi 2 B出现了问题。当我尝试安装Fast - Corner Detector时，我在屏幕上看到了这个问题< / p>

pi@raspberrypi ~/workspace/fast/build $ make

我安装了Cmake（sudo apt-get cmake），Gcc（4.6.3）和OpenCV。

我该如何解决这个问题？

Answer 1

Raspberry Pi是ARM，-msse *是否适用。基于CMakeFile，它们检测ARM和禁用的SSE标志。也许它不适合你，也许是因为不同的cmake版本

尝试更改此

IF(DEFINED ENV{ARM_ARCHITECTURE})

到

IF(DEFINED $ENV{ARM_ARCHITECTURE})

这是CMakeLists.txt

中的第34行

如果修复不起作用，则可以通过编辑CMakeLists.txt手动启用ARM指定的标志

删除它：

IF(DEFINED ENV{ARM_ARCHITECTURE})
  SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mfpu=neon -march=armv7-a")
ELSE()
  SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mmmx -msse -msse -msse2 -msse3 -mssse3")
ENDIF()

并替换为此

SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -mfpu=neon -march=armv7-a")

也许在github上报告一个问题并告诉作者。

编辑：您想在https://github.com/uzh-rpg/fast/blob/master/CMakeLists.txt

中进行这些修改

在编译之前尝试设置导出ARM_ARCHITECTURE = 1

SVO：Fast - Coner Detector - 安装：Plain CMake（无ROS）
