linux - 在 Raspberry Pi 上使用 oxfRPiCameraVideoGrabber 时出现问题

Question

我目前正在学习 Adafruit 的 CreepyPortrait 教程，但在我的 RaspberryPi 上制作该项目时遇到问题

终端输出如下:

pi@raspberrypi ~/openFrameworks/apps/myApps $ git clone http://github.com/tdicola/creepyportrait

Answer 1

来自config.make :

ifeq ($(PROJECT_ARCH),armv6l)
# Explicitly use GCC 4.7 on Raspberry Pi. This is necessary on Raspbian
# because the installed GCC version doesn't support C++11.
PROJECT_CXX = g++-4.7
PROJECT_CC = gcc-4.7
endif

您的错误:

make[1]: g++-4.7: Command not found

表示您(可能)有 g++ 4.6，但没有 g++ 4.7。

根据GCC 4.7.1 in Raspbian :

by plugwash » Mon Jul 16, 2012 3:29 pm: We do have 4.7.1 in raspbian (package gcc-4.7), it just isn't the default. The same is true of all ports of debian wheezy EXCEPT i386 and amd64.

您应该能够安装该软件包(未经我测试)。
