Hi guys,

Sorry if the question was already answered before (couldn't find any answer in the forum) !

Could someone please point me the a Linux debugger with support of FASM (32/64-bit) ?
I found FDGB (http://board.flatassembler.net/topic.php?t=9689), but it only support Linux 64bits.

Does someone tried IDAPro on Linux?

This is the right debugger for Linux: EDB

The development goes slow and the last version is accessible only in source form (old and disgusting habit of the Linux developers ) but the debugger is pretty useful and is not front-end of some console tool (another disgusting habit of the Linux developers )

Hi JohnFound,

Thanks for EDB. Any one else ?

Well, there are bunch of gdb front ends (for example ddd) but all these sucks really.

Also, there is an very interesting pure assembly GUI debugger: AsmBug

Unfortunately, it is long time abandoned and not supported.
I was never able to run it with the recent Linux distributions...
Maybe some day I will try to fix it or to write my own...

OK. So how Fasm guys are doing on Linux?
Are they using EDB?

You may also try ALD.
Well it seems to be abandoned too.

Well, I can write about myself:
1. If it is possible, I am trying to deal with the problem without debugger. Using "debug.asm" library from FreshLib I can easy output debug messages and register and memory values during the program execution, so in the most cases I can live without debugger.

2. In the remaining cases, when I need to stop the program and to examine the stack, and to execute the instructions one by one, I am using EDB, when I am in Linux. (well, moderately using some bad words)
When I am in Windows and need to debug some Linux program, I am using gdb or ddd, furiously swearing.

what about IDA?

I hear that it's very good, albeit expensive.
And the free version is Windows only, no?

Thanks guys. I'll check them all.

I have found no suitable 32/64-bit debugger, sadly.. I simply use FDBG when doing 64-bit assembly in linux (which is my main platform nowadays), and ALD when doing 32-bit assembly. I've tried compiling ALD on a 64-bit system - but its not supported, it has no 64-bit support, and will not even build (let alone run).

I dont mind too much using two seperate programs.. they are quite similar, so its not too much of a hassle to switch between the two. (Both are terminal-based, of course - rather than GUI-based..)

The only other debugger that I know of that will handle both 32-bit and 64-bit is GDB.. however that means dealing with AT&T syntax (although I believe there are ways of making it produce intel-like syntax, but its still pretty ugly), and it was really designed to be used with C, rather than assembly - so it isnt well suited (but it does work, and at a pinch - can be enough, depending what you're attempting to do).
