我正在尝试使用buildroot生成的工具链来交叉编译Android的gcc。
./configure --prefix=/home/Desktop/gcc_5/build/ CC=/home/buildroot-2017.02-rc3/output/host/usr/bin/aarch64-buildroot-linux-uclibc-gcc CXX=/home/buildroot-2017.02-rc3/output/host/usr/bin/aarch64-buildroot-linux-uclibc-g++ CFLAGS="-I/home/buildroot-2017.02-rc3/output/host/usr/include/ -fPIC -static -lc -lgmp -lmpfr -lmpc" LDFLAGS="-L/home/buildroot-2017.02-rc3/output/host/usr/lib" --host=arm-linux --disable-shared --disable-f77 --disable-fc --disable-fortran
配置结果
