This is wrong... The '--dynamic-linker ....' shouldn't be touched! It tells where to found the file at runtime on a ppc-linux machine. This info will be recorded into the executable: ----- clip --------- E:\usr\local\samples>strings tst_linux-gnu.x | less /lib/ld-linux.so.2 __gmon_start__ libc.so.6 _DYNAMIC _GLOBAL_OFFSET_TABLE_ _fini _init __libc_init_first ----- clip --------- Although also this may help to find the file at link-time, the right option would be using the '-rpath-link $prefix/$target/lib', where the $prefix and $target are set to tell where the 'dynamic-linker' file is at link-time... These things were new to me when I wrote the stuff, if one reads the messages since a couple a weeks in this list, about Linux, AIX and Solaris target tools, the '-rpath' (set the link-time/runtime search paths) and the '-rpath-link' (set the search path for the linked-libraries, inside a shared library).

Many thanks to Ian Lance Taylor for clarifying this to all of us! The 'dynamic-linker' file is referenced in the Linux-gnu 'libc.so', here is the 'x86-linux-gnu' target one: ----- clip --------- E:\usr\local\i586-linux-gnu\lib>strings libc.so | grep ld-linux ld-linux.so.2 /lib/ld-linux.so.2 ----- clip --------- Without the '-rpath-link', this would be searched in the current directory and in '/lib'. Of course one can think to install it to '/lib' in the x86-linux-gnu host, the 'ppc-linux-gnu' one is named differently as 'ld.so.2' or something, but keeping all the target stuff in one place would be nicer...
