deibian的交叉编译器gcc-arm-linux-gnueabihf的问题

yuruyi

linux内核实现不使用浮点运算，即使强行使用CFLAG设置针对特定浮点单元优化也一样。
"make V=1"编译内核看看输出的编译命令可以证实这一点。

使用的是 armhf 系统，最好使用arm-linux-gnueabihf-前缀的相应工具链，省得到时候出现无法定位的怪问题。

怎么会没有hf呢……update一下，再说如果不涉及浮点是完全可以的，涉及呢，就有点麻烦了，速度问题或根本不能用

这个帖子说的蛮详细的，区别就是免费下载的lite版本没有硬件浮点运算加速，

The Sourcery CodeBench Lite toolchain does not support armhf. Nor do the Academic or Personal editions.

You'll need to purchase the Standard or Professional editions to get that.

Alternatively, I believe the cross-compiler packages for Ubuntu support the configuration you need (in fact, only that configuration).

If you're not using Ubuntu, then the pre-built Linaro toolchains should be exactly what you need. (The Ubuntu cross compiler packages are/were also built by Linaro people, albeit using the Debian/Ubuntu-specific deb build system.)

在论坛turuoial中是需要hf的，见

$cp cubie_configs/kernel-configs/3.4/cubietruck_defconfig linux-sunxi/.config
$cd linux-sunxi
$git checkout -b cubie-3.4 cubie/sunxi-3.4
$make ARCH=arm menuconfig
$-->change as you want-->and save the new config
$make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage modules
