6.13. System Libraries
When you are building the source application on Linux, link errors may result because of missing libraries. System libraries may be named differently on Linux or simply don't exist because the APIs are already in the standard libc library. Table 6-21 compares HP-UX system libraries to Linux system libraries in terms of their functionalities.
GNU libc includes a variety of support libraries. See Chapter 3 for a complete listing of the libraries included in the GNU libc.
