To compile the example program on a UNIX system, we can say:
cc -o psamples psamples.c -ldb
to produce an executable program called psamples. You may use any
other compiler options you choose, but the `-ldb' option must
appear in the cc command line following any and all source
(`*.c') and object (`*.o') file names, in order to instruct
the loader to search the DB library for any functions that the program
needs (in this case, isigopen and getvec). Some programs
will need additional libraries, and the corresponding `-l' options
can usually be given before or after the `-ldb' option.
Each MS-DOS C or C++ compiler has its own idiosyncratic syntax, so no general rule can be given for MS-DOS. With Microsoft C/C++, use:
cl psamples.c -link db
With Borland C/C++, use:
bcc -LLIBDIR psamples.c db.lib
where LIBDIR is the directory in which `db.lib' (the DB library) has been installed. (Substitute `tcc' for `bcc' if you are using Turbo C or C++.) See your compiler manual for further information.
