During our approach to get the raspberry pi3 and gentoo with an aarch64 kernel
and userland running i tried to cross compile a "native compiler for aarch64".

I also tried various target triplets
aarch64-linux-gnu and aarch64-armv8a-linux-gnueabi. Nut as far as i know
aarch64-linux-gnu is right.

I tried on the Raspberry pi 64 bit with the "C only gcc":
Pi_3 64_bit ~ # cat main.c
#include
#include
int main(int argc, char** argv)
{
printf("sizeof int64_t=%d\n&

typedef long intint64_t;
typedef long long int int64_t;

I purged all temporary build data, added
"--with-sysroot=/opt/aarch64-none-linux-gnu" to the configure line and rebuild
again. The same error.

Now as i got a c++ compiler but no libstdc++ on the target, i try to use the
gentoo tools to emerge (compile) the complete gcc on the target. Let it run
over night whatever is needed. It is just a
