Creating a shared-object file on UNIX or Linux

To create a shared-object file on UNIX or Linux:

Load the abs.o object file into the abs.so shared library, as the following example shows:
```
/compilers/bin/cc -K abs.o -o abs.so

ld -G abs.o -o abs.so
```
Put the shared library in a directory on which user informix has read permission and set the permissions to 755 or 775 so that only the owner can write to the shared libraries.
```
# ls -ld /usr/code
drwxr-xr-x 12 informix devel 2560 Feb 25 05:27 /usr/code 
# chmod 775 /usr/code/abs.so
drwxrwxr-x 12 informix devel 2560 Feb 25 05:27
   /usr/code 
```
