我试图交叉编译的GNU科学图书馆（GSL，V1.16），用于ARM架构（特别是树莓派）。 我已经使用了以下配置;
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"
我收到以下错误信息：
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

我编译64位Linux的Gentoo系统上。 我已经使用了Gentoo工具链来建立我的交叉编译器。 什么我做错了任何指针的高度赞赏。
提前致谢！
