compiling exmap on Ubuntu 8.04

I downloaded the exmap package, but it doesn't seem to include the kernel module, just the binary which isn't very useful so I tried to compile it. Here's the make output:

Code:

Wait: you tried to compile the binary?

Have you tried:

sudo apt-get install exmap

???

Anyway

Code:

cc1plus: warnings being treated as errors

... check the compile string if you want warnings to be ignored.

Code:

exmtool.cpp:35: warning: deprecated conversion from string constant to ‘char*’

- the code you are using is too old for the compiler you have. There are sections which are no longer supported.

The error location is given to you - you can always go into the code and correct it by using a non-depreciated method to convert a string-constant into a char.

No I tried to compile the source. Yes I apt-got it, but whoever packaged it only provided the supporting programs and left out the kernel module which it requires.

How do I change the compile string to ignore warnings? Where is the compile string? Or how do I use an older compiler? How old do I need? As far as correcting the code myself, I don't know C++.

Used to work - tried it quite a while back (on Ubuntu IIRC).
I just pulled the source directly, and it also fails. Probably no longer maintained.

Depending on what you are looking for, have a look at /proc/<pid>/smaps.
There is a module on CPAN, and some perl to format it lurking on the 'net (smem.pl maybe ... ???)
