Hi,
The following code fails to build with OE Aarch64 toolchain with
current kernel headers. While ugly, the code is a reduced testcase
from fuse build failure (
https://bugs.launchpad.net/linaro-oe/+bug/1087757 ) and the same fuse
code compiles on all other architectures. Before I send a workaround
for upstream, I'd like to know how we can end up with different
definitions for int64_t when that happens on no other architectures -
something wrong with the generic kernel headers?
Testcase:
#include <sys/types.h>
#define __s64 int64_t
#include <signal.h>
int main(int argc, char **argv)
{
int64_t x=4;
return x;
}
Failure:

-save-temps --sysroot=/data/oe/build/tmp-eglibc/sysroots/genericarmv8
