libst-dev binary package in Ubuntu Noble riscv64

 The State Threads library has an interface similar to POSIX threads.
 .
 However, the threads are actually all run in-process. This type of
 threading allows for controlled schedualing points. It is highly useful
 for designing robust and extremely scalable internet applications since
 there is no resource contention and locking is generally unnecessary.
 .
 It can be combined with traditional threading or multiple process
 parallelism to take advantage of multiple processors.
 .
 This package contains the development files for compiling programs.
