Hi i am new to linux world ! i m using RedHat 9 on my development system. I m trying to port uClinux on blackfin processor. for that i need to use linux on my developement host computer.
I tried to compile the uClinux kernel.
procedure is as follows :
first i installed blackfin toolchain to compile uClinux kernel.
then i export the path of tool chain in terminal window.
then make menuconfig.
then make clean .
and finally make.
i found this error message :
