FIRST,when i carry on sudo ./ltib -c,

the error is :

according to the error message: "arm-linux-gnueabihf-gcc: error: -mfloat-abi=soft and -mfloat-abi=hard may not be used together"

You are using both 'soft' and 'hard' floating point setting.

So you may use "-mfloat-abi=hard" only in the LTIB configuration. By default, the toolchain is using gcc-4.6.2. If you use a different compiler, you may need a new toolchain.

[xiexp]

i get a new toolchain where is gcchf-4.7.while carry on the ./ltib -c ,it occur a problem like the arm-linux-gnueabihf-gcc: error: -mfloat-abi=soft and -mfloat-abi=hard may not be used togethe.

when i compile without kernel ,the promble whichi is ld-linux.so.3(GLIBC_2.4)   is needed by base_libs-1.2-1

[jimmychan]

Have you try -distclean first? or remove everything in rpm/BUILD/ ?

I tried to use the default toolchain gcc-4.6.2 with -mfloat-abi=hard. The build is fine without error.

[xiexp]

yeah,when i follow the instruction without error, while when i instead of the compile ,the error is coming.

there is not person meet this question?
