一、arm-gcc環境配置
tar xvf rock3288-kernel-arm-linux-gcc -C /opt
vim .basgrc 在最後面添加
export PATH=/opt/gcc-linaro-arm-linux-gnueabihf-4.9/bin:$PATH
用arm-linux-gnueabihf-g++ -v 會提示找不到文件或路徑
我用的是Ubuntu16.04 x64, 需要下載32位庫，百度。
配置成功後： arm-linux-gnueabihf-g++ -v 可以看到版本信息
二、qt5.9 arm-qmake
1、qt-everywhere-opensource-src-5.9.0/qtbase/mkspecs$ cp -r linux-arm-gnueabi-g++/ linux-arm-gnueabihf-g++/
2、修改linux-arm-gnueabihf-g++ qmake.conf 爲
#
# qmake configuration for building with arm-linux-gnueabihf-g++
#
MAKEFILE_GENERATOR = UNIX
CONFIG += incremental
QMAKE_INCREMENTAL_STYLE = sublib
include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)
# modifications to g++.conf
QMAKE_CC = arm-linux-gnueabihf-gcc
QMAKE_CXX = arm-linux-gnueabihf-g++
QMAKE_LINK = arm-linux-gnueabihf-g++
QMAKE_LINK_SHLIB = arm-linux-gnueabihf-g++
# modifications to linux.conf
QMAKE_AR = arm-linux-gnueabihf-ar cqs
QMAKE_OBJCOPY = arm-linux-gnueabihf-objcopy
QMAKE_NM = arm-linux-gnueabihf-nm -P
QMAKE_STRIP = arm-linux-gnueabihf-strip
load(qt_config)
3、 ./configure --prefix=/usr/local/qt5.9-arm-linux -opensource -release -shared -xplatform linux-arm-gnueabihf-g++ -no-opengl -nomake examples
4、 make 時會有錯誤提醒
1、
