用于ARM的交叉编译GSL 1.16 [英] Cross-compiling GSL 1.16 for ARM

问题描述

我试图交叉编译用于ARM体系结构(特别是Raspberry Pi)的GNU科学库(gsl，v1.16).我已经使用以下内容进行配置；

I am trying to cross-compile the GNU Scientific Library (gsl, v1.16) for ARM architecture (specifically the Raspberry Pi). I have used the following to configure;

CROSS=armv6j-hardfloat-linux-gnueabi
./configure --host=x86_64-pc-linux-gnu --build=$CROSS --target=$CROSS \
CC=/usr/bin/$CROSS-gcc \
CXX=/usr/bin/$CROSS-g++ \
AR=/usr/bin/$CROSS-ar \
RANLIB=/usr/bin/$CROSS-ranlib \
CFLAGS="-march=armv6 -mfloat-abi=hard -mfpu-vfp"

我收到以下错误消息:

libtool: compile:  /usr/bin/armv6j-hardfloat-linux-gnueabi-gcc 
-DHAVE_CONFIG_H -I. -I.. -I.. -march=armv6 -mfloat-abi=hard -mfpu=vfp 
-MT read.lo -MD -MP -MF .deps/read.Tpo -c read.c -o read.o

我正在64位Linux Gentoo系统上进行编译.我使用了Gentoo工具链来设置我的交叉编译器.高度赞赏我在做什么的任何指针.

I am compiling on a 64 bit Linux Gentoo system. I have used the Gentoo toolchain to set-up my cross-compiler. Any pointers to what I am doing wrong are highly appreciated.

提前谢谢！

推荐答案

您的配置不正确，无法交叉编译build =(您的x86 gcc)和host = target =(arm-tool-chain).下面的命令.

Your configuration was not correct ,to Cross-compile build=(your x86 gcc),and host=target=(arm-tool-chain).Try this below command.

./configure --host=armv6j-hardfloat-linux-gnueabi --build=x86_64-pc-linux-gnu --target=armv6j-hardfloat-linux-gnueabi \ CFLAGS="-march=armv6 -mfloat-abi=hard -mfpu-vfp"

./configure --host=armv6j-hardfloat-linux-gnueabi --build=x86_64-pc-linux-gnu --target=armv6j-hardfloat-linux-gnueabi \ CFLAGS="-march=armv6 -mfloat-abi=hard -mfpu-vfp"
