Introduction to Pth

The Pth package contains a very portable POSIX/ANSI-C based library for Unix platforms which provides non-preemptive priority-based scheduling for multiple threads of execution (multithreading) inside event-driven applications. All threads run in the same address space of the server application, but each thread has its own individual program-counter, run-time stack, signal mask and errno variable.

Installation of Pth



Don't add the --enable-pthread parameter to the configure command below else you will overwrite the pthread library and interface header installed by the Glibc package in LFS.

Install Pth by running the following commands:

./configure --prefix=/usr &&

To test the results, issue: make check.

Now, as the root user:

make install &&
