Hi, I'm having trouble building syzkaller (which is primarily written in Go) in a Debian schroot for amd64 using qemu emulation. That is, I'm using a chroot filled with arm64 binaries, running them on an x86_64 system using a setup such as described in [1]. The specific chroot I am using can be set up using the setup-buildchroot[2] which is part of the xfstests-bld repository.
[1] https://wiki.debian.org/QemuUserEmulation [2] https://github.com/tytso/xfstests-bld/blob/master/setup-buildchroot The goal of this exercise is to create an android-xfstests[3] test appliance using a x86_64 based build machine (because good luck finding a performant armhf or arm64 build system) which includes syzkaller. [3] https://thunk.org/android-xfstests When I run make in a Debian stretch-arm64 chroot, while trying to build syzkaller, I get the following failure messages. (See attached). Running make and gcc and binutils using arm64 to run the arm64 binaries work just fine; I assume this is some kind of go-specific runtime issue? Any help or suggestions would be greatly appreciated. Thanks!! - Ted <ty...@stretch-arm64-chroot.cwcc> {/usr/projects/xfstests-bld/build-arm64/go/src/github.com/google/syzkaller} 1008% make GOOS=linux GOARCH=arm64 go install ./syz-manager # github.com/google/syzkaller/sys/targets runtime: failed to create new OS thread (have 2 already;
