RE: Using debugger under Linxu...
Very nice. :) DDD looks good. Makes getting around a little nicer, but for the times when the gui get's in the way, you can just use gdb through ddd's command line interface window. :) Thanks Erik! -Original Message- From: Erik van der Knaap [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 24, 2000 12:02 AM To: [EMAIL PROTECTED] Subject: Re: Using debugger under Linxu...

Re: Using debugger under Linxu...
Hello, I loked at the latest gdb. It is not a GUI based one?. Is there any good GUI based debugger based on gdb?. also, If I do some changes in some section of the code (for example commandline.ui) and want to use the gdb to find out where UI failed (i.e. the to find the stupid mistake I have made in the code) how do I do that without doing any changes in the make file?. thanks Prabha ___ [EMAIL PROTECTED] http://www.freeamp.org/mailman/listinfo/freeamp-dev

I use gdb. It works most of the time, but freeamp is complex enough and has enough threads going on that gdb has an annoying tendency to segfault when freeamp does.. makes it fun to debug =) 2) How to change the make file to be able to debug?. (The make file is too complicated for me to follow). If you built freeamp from sources yourself, you shouldn't have to change anything.. thanks in advance.. Prabha To debug segfaults and the like, all you really need to do is: gdb freeamp gdb startup junk (gdb) run ... mess with it, wait for a segfault, etc... (gdb) bt and it'll give you a stack trace of where the problem occurred. Isaac ___ [EMAIL PROTECTED] http://www.freeamp.org/mailman/listinfo/freeamp-dev

Do you have any hints for working around that? Everytime I try to debug a segfault gdb segfaults. Paul ___ [EMAIL PROTECTED] http://www.freeamp.org/mailman/listinfo/freeamp-dev
