Hi Thang Tran,

I'm new to Fiasco and L4Re. I want to write a new program in C++ which will run on L4Re. I'm looking at the simple client server example in the l4/pkg/examples/clntsrv directory for my reference. I was able to get it compiled eventually on L4Re, but I have no idea how to run it. Is there anyway that I can run examples/clntsrv package just like we run the hello package by using grub2iso and qemu?

For some explanation on how client/server programming works, please see http://wiki.tudos.org/L4Re_simple_client_server_example Setting up a run in Qemu works like this: 1) You compile L4Re and your own program. (You already did that.) 2) You setup l4/conf/Makeconf.boot once. There is an example file that you can start from. The relevant required changes are: * set MODULE_SEARCH_PATH to include your Fiasco.OC build dir (by default that's build/ in the kernel directory) * set QEMU_OPTIONS as needed (leaving the default shoud be ok) 3) For every program setup you need two things A) A modules.lst entry describes the kernel and binary you want to load. Examples are in l4/conf/modules.lst - the syntax is similar to GRUB config files. B) A Lua init script to launch your application(s). Again, examples are both in l4/conf and sometimes in the respective program direc- tories. For the clntsrv example, there is a clntsrv.cfg file in l4/pkg/examples/clntsrv Bjoern -- Dipl.-Inf.
