hello

can someone help me here what did i do wrong ,i have been trying to do camkes-vm-linux and i have followed the instruction on sel4-tutorials when i run ninja to build the file i have got an error as below ========================================================================== ninja [5/127] Building C object camkes-vm-li...ents/Init/src/virtio_net_vswitch.c.obj FAILED: ccache /usr/bin/gcc --sysroot=/home/sel4/sel4-tutorials-manifest/camkes-vm-linux_build -I../projects/camkes/vm/components/Init/src -I../projects/camkes/vm/components/VM/configurations -Icamkes-vm-linux/vm0/include -I../kernel/libsel4/include -I../kernel/libsel4/arch_include/x86 -I../kernel/libsel4/sel4_arch_include/x86_64 -I../kernel/libsel4/sel4_plat_include/pc99 -I../kernel/libsel4/mode_include/64 -Ilibsel4/include -Ilibsel4/arch_include/x86 -Ilibsel4/sel4_arch_include/x86_64 -I../projects/sel4runtime/include -I../projects/sel4runtime/include/mode/64 -I../projects/sel4runtime/include/arch/x86 -I../projects/sel4runtime/include/sel4_arch/x86_64 -Iprojects/musllibc/build-temp/stage/include -Ilibsel4/autoconf -Ikernel/gen_config -Ilibsel4/gen_config -I../tools/camkes/libsel4camkes/include -I../projects/seL4_libs/libsel4debug/include -I../projects/seL4_libs/libsel4debug/arch_include/x86 -I../projects/seL4_libs/libsel4debug/sel4_arch_include/x86_64 -I../projects/util_libs/libutils/include -I../projects/util_libs/libutils/arch_include/x86 -Iprojects/util_libs/libutils/gen_config -I../projects/util_libs/libplatsupport/include -I../projects/util_libs/libplatsupport/plat_include/pc99 -I../projects/util_libs/libplatsupport/arch_include/x86 -Iprojects/util_libs/libplatsupport/gen_config -I../projects/seL4_libs/libsel4muslcsys/include -I../projects/util_libs/libcpio/include -I../projects/seL4_libs/libsel4utils/include -I../projects/seL4_libs/libsel4utils/sel4_arch_include/x86_64 -I../projects/seL4_libs/libsel4utils/arch_include/x86 -I../projects/seL4_libs/libsel4vspace/include -I../projects/seL4_libs/libsel4vspace/arch_include/x86 -I../projects/seL4_libs/libsel4vka/include -I../projects/seL4_libs/libsel4vka/sel4_arch_include/x86_64 -I../projects/seL4_libs/libsel4vka/arch_include/x86 -Iprojects/seL4_libs/libsel4vka/gen_config -Iprojects/seL4_libs/libsel4utils/gen_config -I../projects/seL4_libs/libsel4simple/include -I../projects/seL4_libs/libsel4simple/arch_include/x86 -I../projects/seL4_libs/libsel4platsupport/include -I../projects/seL4_libs/libsel4platsupport/arch_include/x86 -I../projects/seL4_libs/libsel4platsupport/plat_include/pc99 -I../projects/seL4_libs/libsel4simple-default/include -I../projects/util_libs/libelf/include -Iprojects/seL4_libs/libsel4muslcsys/gen_config -I../projects/seL4_libs/libsel4sync/include -I../projects/projects_libs/libvirtqueue/include -Icamkes-vm-linux/libsel4camkes/gen_config -Iprojects/sel4runtime/gen_config -I../projects/seL4_libs/libsel4allocman/include -I../projects/seL4_libs/libsel4allocman/sel4_arch/x86_64 -I../projects/seL4_libs/libsel4allocman/arch/x86 -I../projects/seL4_libs/libsel4vmm/include -I../projects/util_libs/libpci/include -I../projects/util_libs/libethdrivers/include -I../projects/util_libs/libethdrivers/plat_include/pc99 -I../projects/util_libs/libethdrivers/arch_include/x86 -Iprojects/util_libs/libethdrivers/gen_config -Iprojects/util_libs/liblwip/gen_config -Iprojects/util_libs/libpicotcp/gen_config -Iprojects/seL4_libs/libsel4vmm/gen_config -Icamkes-vm-linux/vm/gen_config -I../projects/projects_libs/libvswitch/include -I../projects/camkes/global-components/components/FileServer/libFileServer-client/. -m64 -march=nehalem -D__KERNEL_64__ -g -nostdinc -fno-pic -fno-pie -fno-stack-protector -fno-asynchronous-unwind-tables -ftls-model=local-exec -mtls-direct-seg-refs -Wno-main -std=gnu11 -MD -MT camkes-vm-linux/CMakeFiles/vm0.instance.bin.dir/__/projects/camkes/vm/components/Init/src/virtio_net_vswitch.c.obj -MF camkes-vm-linux/CMakeFiles/vm0.instance.bin.dir/__/projects/camkes/vm/components/Init/src/virtio_net_vswitch.c.obj.d -o camkes-vm-linux/CMakeFiles/vm0.instance.bin.dir/__/projects/camkes/vm/components/Init/src/virtio_net_vswitch.c.obj -c ../projects/camkes/vm/components/Init/src/virtio_net_vswitch.c ../projects/camkes/vm/components/Init/src/virtio_net_vswitch.c: In function ‘virtio_net_notify_vswitch_send’: ../projects/camkes/vm/components/Init/src/virtio_net_vswitch.c:50:23: warning: implicit declaration of function ‘virtqueue_driver_dequeue’ [-Wimplicit-function-declaration] int dequeue_res = virtqueue_driver_dequeue(node->virtqueues.send_queue, ^ ../projects/camkes/vm/components/Init/src/virtio_net_vswitch.c: In function ‘emul_raw_tx’: ../projects/camkes/vm/components/Init/src/virtio_net_vswitch.c:123:13: error: unknown type name ‘virtqueue_t’ virtqueue_t *destbuff;
