Building and running the net example

The build scheme for the net example looks as follows:

Building the net_client and net_server entities

When building the net_client and net_server entities, they must be linked to the vfs_remote library.

x86_64-pc-kos-gcc -o net_client -L $SDK/sysroot-x86_64-pc-kos/lib net_client.c -lvfs_remote

x86_64-pc-kos-gcc -o net_server -L $SDK/sysroot-x86_64-pc-kos/lib net_server.c -lvfs_remote

Hereinafter: SDK=/opt/KasperskyOS-StarterKit-<version>.

Building the initializing entity

Building the einit entity will require the net_client.edl.h and net_server.edl.h files that need to be generated using the NK compiler:

nk-gen-c -I $SDK/sysroot-x86_64-pc-kos/include net_client.edl

nk-gen-c -I $SDK/sysroot-x86_64-pc-kos/include net_server.edl

The code of the initializing entity (einit.c) is generated by using the einit tool:

einit -I $SDK/sysroot-x86_64-pc-kos/include -I . init.yaml -o einit.c

Building the einit initializing entity:

x86_64-pc-kos-gcc -I . -o einit einit.c

Building a solution image

Now you just need to build a solution image containing the KasperskyOS kernel image (kos-qemu), and the net_client, net_server, vfs_entity and einit entities:

makeimg --target=x86_64-pc-kos \

--sys-root=$SDK/sysroot-x86_64-pc-kos \

--with-toolchain=$SDK/toolchain \

--ldscript=$SDK/libexec/x86_64-pc-kos/kos-qemu.ld \

--img-src=$SDK/libexec/x86_64-pc-kos/kos-qemu \

--img-dst=kos-qemu-image \

net_client net_server $SDK/sysroot-x86_64-pc-kos/bin/vfs_entity

The einit entity does not need to be indicated because it will be automatically included in the solution image.

Running the net example

To run the built solution image under QEMU, run the following command:

qemu-system-x86_64 -m 1024 -serial stdio -kernel kos-qemu-image

Building and running the net example using the build.sh script containing all of the above commands
