Question

我使用以下这个（http://www.cloud-rocket.com/2013/07/...or-beaglebone/）链接在beablebone black上进行交叉编辑。但是在遵循此链接时，我在修改qmake.conf文件后遇到了以下错误

1）修改了qmake.conf的详细信息：

enter code here
# qmake configuration for building with arm-linux-g++
#

include(../../common/linux.conf)
include(../../common/gcc-base-unix.conf)
include(../../common/g`enter code here`++-unix.conf)
include(../../common/qws.conf)

# modifications to g++.conf
#Toolchain

#Compiler Flags to take advantage of the ARM architecture
QMAKE_CFLAGS_RELEASE = -O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-      abi=softfp
QMAKE_CXXFLAGS_RELEASE = -O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp

QMAKE_CC = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/gcc
QMAKE_CXX = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/g++
QMAKE_LINK = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/g++
QMAKE_LINK_SHLIB = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/g++

# modifications to linux.conf
QMAKE_AR = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/ar cqs
QMAKE_OBJCOPY = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/objcopy
QMAKE_STRIP = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/strip
load(qt_config)

2）错误：

make: g++: Command not found

有人可以帮助解决错误吗？

Answer 1

对我来说，编译器是未知的。你是否按照指示“正确”安装了它？：

tar -C / -xjf angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2

如果您错过了“-C /”，这可能是一个原因，因为qmake.conf直接引用了路径。

您可以查看：

 find / -name "arm\-angstrom\-linux\-gnueabi" 2>/dev/null

Answer 2

您应该在PATH上安装g ++。通过调用以下命令确保可以访问g ++：哪个g ++
