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

[Piotr]

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 there; this bug database is for issues in upstream QEMU. The assert() you have hit is not in upstream QEMU at all, so it must be something that Xilinx have added. For questions about Xilinx's version, you should talk to them, not us.

That said, I think the answer is likely to be "they don't support building for 32-bit hosts", and you'll find that if you use a 64-bit host OS instead it will work.
