library catalogue program

[Slavrix]

hey guys, i got an assingment due and i was wondering if you could please help me to debug this program.

5 files,
ass1.h
ass1.cpp
main.cpp
Makefile.txt (needs to be renamed to makefile for it to be used properly)
ass1.txt(needs to be renamed ass1.dat to be used[its the database for the books])

to be compiled for a linux environment

the files to be loaded needs to change from text to binary file type, i havnt been able to work out how to do that yet

[jwenting]

no, we're not going to do that. We're certainly not going to sheepishly compile and run your code and fix it for you.

[iamthwee]

Ask specific questions. Post your code here not as attachments. Read the forum rules etc...

[Slavrix]

well it was worth a try

i fixed it all now anyhow, except one thing, my makefile.

CC=g++

all:	ass1

ass1:	main.o ass1.o
	$(CC) main.o ass1.o -o ass1

main.o:	main.cpp ass1.h
	$(CC) -c main.cpp

ass1.o:	ass1.cpp ass1.h
	$(CC) -c ass1.cpp

there it is, and here is the error (im using SSH to compile with, its connected to uni servers running ubuntu)

$ make
make: Fatal error in reader: Makefile, line 3: Unexpected end of line seen

[SpS]

Try this

CC=g++
 
ass1:	main.o ass1.o
	$(CC) main.o ass1.o -o ass1
 
main.o:	main.cpp ass1.h
	$(CC) -c main.cpp
 
ass1.o:	ass1.cpp ass1.h
	$(CC) -c ass1.cpp

[Slavrix]

still not working, error got bigger

mksh: Warning: newline is not last character in file Makefile
Current working directory /home/ug/q/nt647
make: Fatal error in reader: Makefile, line 3: Unexpected end of line seen

[SpS]

Try implicit rules

CC = g++
 
ass1: main.o ass1.o
	$(CC) main.o ass1.o -o ass1
 
main.o:	main.cpp ass1.h
 
ass1.o:	ass1.cpp ass1.h

[SpS]

I just downloaded your files(.cpp & .h) and tried the Makefile. Makefile just works fine. The problem is with your codes.

[Slavrix]

??

that code there btw is out of date, i have almost completly re-written it all, (except the main.cpp)

i put all my code into one file and compiled it and it worked fine (my new stuff) but when i split it again, for the makefile to do its job, it didnt complie

[SpS]

Post your corrected codes(all .cpp and .h files). I will try them at my end with the Makefile.

[Slavrix]

ok, i got my makefile working, but there seems to still be an error that i cant find , int he code itself, if possible could you see if you could find it ?

dont forget to change the makefile.txt back to makefile (just a reminder :P )

the error im getting now is

main.cpp:1: error: stray '\239' in program
main.cpp:1: error: stray '\187' in program
main.cpp:1: error: stray '\191' in program

[Slavrix]

ok, fixed, that, now this error instead :"(

$ make
g++ -c main.cpp
g++ -c ass1.cpp
g++ main.o ass1.o -o ass1
Undefined first referenced
symbol in file
DisplayRecords() main.o
ld: fatal: Symbol referencing errors. No output written to ass1
collect2: ld returned 1 exit status
*** Error code 1
make: Fatal error: Command failed for target `ass1'

use that main

[SpS]

That's a linker error. It seems that you don't have defination of DisplayRecords() .

[Slavrix]

yea, i jsut had a thoroguh read of it, and found teh problem, please come and shoot me where i stand

DisplayRecord();
DisplayRecords();

i mixed it up in one spot :)

the makefile problems i was haveing seemed to be coming from invisible characters, i got my mate to retype on on his linux and send to me and i used that fine

but yea mate, thnx again for ur help
