我正在尝试为 ARM 架构(特别是 Raspberry Pi)交叉编译 GNU 科学库(gsl,v1.16)。我已经使用以下配置;
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

我在 64 位 Linux Gentoo 系统上编译。我已经使用 Gentoo 工具链来设置我的交叉编译器。任何指向我做错了什么的指针都非常感谢。
提前致谢!
