GDB Question??

How do you make GDB step through function calls when the function is in a different .h/.cpp file (different class)?

I had everything in one file, and when it seg faulted, it gave me the exact line within that class where the problem occurred. Now I just spent a ton of time separating everything out into different .h/.cpp files, and I have lost that functionality... Doh... It just says "seg fault in function of class x blah blah" without the line number.

Code:

---

Program received signal SIGSEGV, Segmentation fault.
0x08049c75 in Trie::Getptr2item ()

---

No line numbers anymore :(

-----

Alternatively, is there a way to use Makefiles with Visual C++ (or any other Windows programs)?

Set a breakpoint in said class. I don't remember how and haven't done it for years, but gdb has help.

Compile everything with the "-g" flag to get better debug information.

Genius!

Code:

---

Program received signal SIGSEGV, Segmentation fault.
0x08049c75 in Trie::Getptr2item (this=0x8100008, x=@0xbff898b8) at Trie.cpp:100
100                    if ( current->Getptr(j) == 0 )

My makefile was only using -g for the main program, not all the classes.

Thanks!

Another question: is there a way to run your main file in Visual C++ with command line parameters?

In linux at my school, I do "./proj < input1.txt" (proj is my main)

Is there a way to do that with Visual C++?

Project -> Settings.
On the debug tab, you can set the command line.

Yes, you can pass command line parameters to programs in Visual C++. Again, this is something you should be able to find if you do a modicum of searching in the help files, or just by poking around the VC++ interface.

Ah yes, there we go.

It keeps saying my file isn't found.

If I put: "inputfile" it runs, but doesn't actually get that input (ignores what I typed)

If I put: "< inputfile", it says file not found.

Is the < valid? Or only linux?

Ah I see, I had to set the working directory field.
