Dear Friends,

now that i have a working cross compiler i would like to ask
(again) about an easy way to run it.

>/usr/local/ppc/powerpc-linux/lib/ -o second secondtest.c

>copy over to LinuxPPC... and it runs!!
>hello world!

i've tried:

>user# gcc -b powerpc-linux -o thirdb thirdtest.c

which gives the error:

>as: unrecognized option `-ppc'

i assume this is because the wrong "as" is being invoked?
how would i get it to invoke the powerpc-linux-as (which
IS in the PATH btw)

>
>user#  powerpc-linux-gcc -I /usr/local/ppc/powerpc-linux/include/ -L 
>/usr/local/ppc/powerpc-linux/lib/ -o third2 thirdtest.c

that one's okay, but

>user#  powerpc-linux-gcc -I /usr/local/ppc/powerpc-linux/include/ -L 
>/usr/local/ppc/powerpc-linux/lib/ -static -o third2 thirdtest.c

gives:

>/usr/local/ppc/powerpc-linux/lib/crt1.o(.text+0x54): undefined reference 
>to `__libc_init_first'
>collect2: ld returned 1 exit status

which looks like one of those glib5/glib6 type problems. which would
suggest it's picking up the wrong libraries. how do i set this?

in any case the executable isn't dynamic (according to ldd).

in the final analysis it does work and i can product ppc executables
so i want to stress that i'm not complaining. but after all the trouble
i've been through, to not get it 100% working, right when i'm on the 
5-yard-line...

thanks and best regards,
   trevor woerner
