cross compilation issue with openssh


Hi Folks,

I have compiled openssl with openssl.mk that has been attached. It was compiled successfully.
I am compiling the openssh with openssh.mk that has been also attached.

here :
crosscompiler path:
/opt/toolchains/uclibc-crosstools-gcc-4.4.2-1


I am facing the compilation issue like as fallows.

Hello Harinath,
I don't know if it will help you, but when I compiled it for ARM I followed this.
