HP UX Software Transition Kit (STK) manual Above example, if you type, Instead

In the above example, if you type:

$ ld main.o -L. -lbar -lc $ mv libme.so /var/tmp

instead of:

$ mv libme.so /var/tmp

$ ld main.o -L. -lbar -lc

the linker finds libme.so in ./ at link time, and the dynamic loader finds libme.so in /var/tmp at run time. At run time, the dynamic loader searches paths to resolve external references made by main in the following order:

1. ./libc.so not found /usr/lib/hpux32/libc.so found

2.SHLIB_PATH to find libbar.so not found

3. ./libbar.so (./libbar.so) found

4.LD_LIBRARY_PATH to find libme.so not found

5.SHLIB_PATH to find libme.so not found

6./var/tmp/libme.so found

7.LD_LIBRARY_PATH to find libc.so not found

8.SHLIB_PATH to find libc.so not found

9.LD_LIBRARY_PATH to find libbar.so not found

Library Example: Linking to Libraries with +b path_list in PA-32 Mode

This example is the same as “Library Example: Linking to Libraries with +b path_list in IPF/PA-64 Mode” (page 134), but this time the program is compiled in PA-32 mode.

$ cc -c +DD32 me.c bar.c main.c $ ld -b me.o -o libme.so

$ ld +compat -b bar.o -o libbar.so -L. -lme +b /var/tmp \PA-32 mode library created $ ld main.o -L. -lbar -lc

$ mv libme.so /var/tmp

When linking main.o, the link order is: 1. ./libbar.so found

2. ./libme.so found

3. ./libc.so not found

4./usr/lib/libc.so found In the above example, if you type:

$ mv libme.so /var/tmp

$ ld main.o -L. -lbar -lc

instead of:

$ ld main.o -L. -lbar -lc $ mv libme.so /var/tmp

the linker issues the following error message:

ld: Can't find dependent library ./libme.so Fatal Error

The linker does not look in /var/tmp to find shared libraries because in PA-32 mode the directories specified by +b pathname are only searched at run time. Because libme.so is specified with the -loption, it is subject to dynamic path searching. At run time, the dynamic loader looks for shared libraries used by main in the following order:

1. ./libbar.so found

2./var/tmp/libme.so found

3./libc.so not found

4./usr/lib/libc.so found
