Cross-Compiling SSH Server

[Rick Woodring]

I am trying to cross compile dropbear 0.43 on an x86 machine running RedHat 9 for an ARM 9 based development board that runs the 2.4.21 kernel (with ARM patches), busybox 1.0.0-RC2, and tinylogin.  I have successfully  built the kernel, busybox, and tinylogin with my GCC cross-compile toolcahinm, but when I tried to use cross-compile dropbear, I received the error show at the bottom.  In order to cross-compile dropbear, I modified the options.h file to select the pieces i wanted to compile and then set my CC and CPP environment variables to arm_920t_le-gcc and arm_920t_le-g++ respectively.  When I ran "./configure --host=armv4l" this is the output it gave me:

[jffs at openRoam dropbear-0.43]$ ./configure --host=armv4l

Any help would be appreciated
