使用LTIB工具生成rootfs报错

xiexp2014

使用的是IMX6开发板，系统是32位的ubuntu12.04，
在使用./ltib过程中，报错
arm-linux-gnueabihf-gcc: error: -mfloat-abi=soft and -mfloat-abi=hard may not be used together
还有就是busybox_unstripped uses VFP register arguments

xiexp2014

具体的错误是

arm-linux-gnueabihf-gcc: error: -mfloat-abi=soft and -mfloat-abi=hard may not be used together

这里提醒你 -mfloat-abi=soft 和  -mfloat-abi=hard  只能用一个。你删了 -mfloat-abi=hard 这个试试。soft的是总可以用的，hard的要硬件支持。

xiexp2014

我的硬件支持hf版本的。使用的是LTIB 工具，配置 -O2 -march=armv7-a -mfpu=vfpv7 -mfloat-abi=hard，然后使用./ltib -c进行编译的时候，就报错了


   

amarant

那你先用soft编译通过再说吧

amarant

我不太清楚LTIB是什么，估计是他给你自动加上了hard的flag

xiexp2014

softfp编译是没问题的。可是和我编译的初衷不一样，我加入了-mfloat-abi=hard。就是不知道为什么会自动配置了soft

amarant

回复 8# xiexp2014


    那你要grep一下原来环境是在那里加上softfp的。然后修改原来环境去掉这个选项

xiexp2014

Ltib路径是可以直接指定的，grep查找不到相关信息
