How to install seastar

[Muhammad Umar]

Hi, am a Bachelors in Electrical Engineering student. I have some experience with  c++ multithreading, including debugging race conditions in my personal project. 

I made a game, and wanted to make a high performance scalable server for it (to learn high performance computing). so, I learned about seastar's design pholosophy and how it achieves maximum hardware performance. I learned about coroutines and other prerequisites for seastar.

But while installing seastar on Ubuntu terminal VM, " sudo ./install-dependencies.sh" worked flawlessly. But hell started after it, when i ran " ./configure.py --mode=release", since it continously said me to install something for like 10-20 times every time i ran that command.

eventually it somehow worked now i am stuck trying to run "ninja -C build/release". there were version conflicts(i think so), and alot of problems i couldn't understand. that's why, currently I am learning build systems, and multi file projects better. 

so, if you can, tell me if i was installing something wrong(or guide me in cpp progression journey)

Hi,

It is possible that install-dependencies.sh is out-of date, or it doesn't install optional dependencies like lttng. Optional dependencies have an opt-out flag when invoking ./configure.py. Without seeing the actual error, I cannot help beyond guessing.

Adding missing dependencies to install-dependencies.sh and sending a patch with the fix is a great way to start contributing.

Botond

Hi,

I restarted a clean build after deleting the previous one. It showed "fmt"  was outdated, and I had to manually install some dependencies too (like doxygen), and it finally worked flawlessly.

Also, I am going to start working on the patch.
