Hi,
Attached are the source files of the memory tracking library and a simple driver program to test the library. But i can't get it to work. I have to define 'MEMTRACK' in order for the memory tracking functions to operate. But after i type 'define MEMTRACK' in the source of the driver program, nothing happened. It's supposed to output a report as a text file, but it didn't.
Pls just download the files and have a run, and tell me if i've doen anything wrong.
thnx in advance
Seems OK to me
> 'define MEMTRACK'
No, you have an #ifdef MEMTRACK
You need to define the symbol on the command line, depending on whether you want (or not) the traced memory routines.
This is my command line
gcc -DMEMTRACK memtrack.c memtrkmn.c
And here are the results.
I use DEVC++ 4 and i went into compiler options and at the 'add the following commands' i try a combination of -DMEMTRACK but nothing works and instead generates errors while compiling. Erros of undefined reference to the mem track functions.
What did i do wrong?
thx again

Pls tell me how to define stuff in order for them to compile, now i can't try out any of the programs from my book's cd rom.
thnx
attached is another program i can't compile. HOW DO I DEFINE???????????? It's got all sorts of undefined reference to such and such ( which are all the functions ).........
pls help
thnx
The code appears to be fine; it compiled under gcc without warnings (which is pretty encouraging, since it's clearly not coded for linux).
Undefined references to functions are a linker problem. You are probably trying to compile main.c on its own, but you need to do the two together.
Let us know what compiler you use, and if possible, what the command line argument you pass to it is (if your IDE handles that, let us know what IDE you're using).
Callou collei we'll code the way
Of prime numbers and pings!
> 'add the following commands'
Mmm, I'm not familiar with DEV-C++, but it is a gcc derivative
The place where you want to add the -DMEMTRACK should be in the compiler 'command line options'.
And please post some exact error messages.
Also, are you including ALL your .c files in the project?
I included all ( 2 total ) the .c files in y devC++ project but when i compile it i got whole bunch of the following errror:
memtrkmn.c
ANSI C++ forbids implicit conversion from `void *' in assignment
any ideas?
Yep. Stop compiling a C++ and compile as C. (Don't have files named .cpp either.)
Quzah.
Hope is the first step on the road to disappointment.
all my filenames are .c but i 'think' i'm compiling as C.
If it's telling you that 'ANSI C++ forbids...' then it isn't compiling as C. What you have is something like this:
char *c;
c = malloc( 200 );
If you compile that as C it's valid. For it to compile as C++ without any errors, you have to do:
char *c;
c = (char *)malloc( 200 );
C++ requires a type cast on void pointers. This is the error you're getting, which tells us you're compiling as C++.
Quzah.
Hope is the first step on the road to disappointment.
Hi sorry i selected the wrong option.
I successsfully compiled it but when it executes it's suppose to output a file name memtrack.txt. But instead nothing happened. Nothing outputed to the stdout and no files created.
Any ideas? please give a hand.
thnx a lot
wait i got it workin.
In my DevC++-> tools and compiler options, i go to compiler commands and type -DMEMTRACK.
One last question. DevC++ doesn't come with documentation teaching stuff like above "-DMEMTRACK" for example. Where can find documentation on using those special commands command-line options?
thnx in advance

found thnx...
at first i was trying to find -D, but on the page it was actualy displayed as -DMARCO
