error: static assertion failed: "arm generic timer needs __Int128 defined"

[piotr-aldec]

Hi,

Accordingly to the instruction from https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842060/QEMU we have downloaded the Xilinx QEMU and tried to build it on Ubuntu 16.04.5 32Bit OS. We have done all the following steps from the instruction: $ git clone git://github.com/Xilinx/qemu.git $ cd qemu $ git submodule update --init dtc $ ./configure --target-list="aarch64-softmmu,microblazeel-softmmu" --enable-fdt --disable-kvm --disable-xen $ make and we have got the error during the compilation: /home/qemu/include/qemu/int128.h:168:1: error: static assertion failed: "arm generic timer needs __Int128 defined" _Static_assert(0, "arm generic timer needs __Int128 defined"); ^ /home/qemu/rules.mak:66: recipe for target 'stubs/qmp_pc_dimm.o' failed

Could you please help to solve this issue.

Thanks, Best Regards, Piotr

Hi,

I think this is caused by you trying to build QEMU for a 32bit host. We no longer support that, allthough this error was unintentional, things will fail at run time since many of the Xilinx machines we emulate require large amounts of emulated RAM (virtual memory space gets exhausted on 32bit hosts).
