uClinux trouble with making kernel

You don't have to do your first thing. Follow this :

In SOPC Builder do "Generate"

Then copy you find your ".ptf" file (it's in you project directory).

in you "nios2-linux/uClinux-dist/" directory do the following :

make vendor_hwselect SYSPTF="XXXXXXXXX" replace the XXXX with your path to your ptf. Example :

make vendor_hwselect SYSPTF="/opt/altera/project/myproject.ptf"

Answer the question.

In the same directory

make menuconfig

select Kernel/Libray/Default Selection/

Select Default all setting (lose changes)

Exit -> Exit -> Save

make

That's all !
