Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am using RedHat Linux 2.6.9-1.667smp on a standard intel desktop and I've written a simple little test program to prove that dbopen works and I just
can't get it to compile properly. I really need help with this one as I'm stuck.
The error message I get is as follows,
cc -g -I/usr/include -c dbtest.c -o dbtest.o
dbtest.c: In function `main':
dbtest.c:14: error: `RECNOINFO' undeclared (first use in this function)
dbtest.c:14: error: (Each undeclared identifier is reported only once
dbtest.c:14: error: for each function it appears in.)
dbtest.c:14: error: syntax error before "rec"
dbtest.c:17: error: `rec' undeclared (first use in this function)
dbtest.c:17: error: `R_FIXEDLEN' undeclared (first use in this function)
dbtest.c:26: warning: assignment makes pointer from integer without a cast
cons: *** [dbtest.o] Error 1
cons: errors constructing dbtest.o
the program is as follows.
rec.flags = R_FIXEDLEN;
rec.cachesize=0; /* use default cachesize */
rec.psize = 0; /* Let system select page size. */
rec.lorder = 0; /* Use current Host ordering. */
rec.reclen = 20;/* 20 byte record length */
rec.bval = '\0';/* Padding char used when fixed length. */
rec.bfname= NULL; /* Don't need to know about internal b-tree. */
the dbm libraries appear to be part of the GNU db libraries rather than the db libraries. All the examples I have found on the internet for dbopen indicate that I should be using <db.h> and setting my pointer as a DB *ptr.
I have found references to RECNOINFO and the other missing defintions in db_185.h - but I don't know what that is or whether I should be using it.
I believe when Berkeley DB is built it automaticaly includes db-1.8.5
compatability. So u must be using BerkeleyDB version 2 or higher. Their
file formats change as often as their underware. If u build DB yourself u
can use a command line switch in the configure file to shut it off. So if u
write any code using db-1,8,5 calls u must include db_185.h. I'm sure if
i'm wrong someone on here will let me know.
