You can read about its many functions with the GNU Info reader: $ info gdb There's a lot more you can do with it than I demonstrated in this article. GNU Debugger is a useful tool in finding bugs. Whatever the cause, bugs are basically everywhere, and it's part of the programmer's job to find and neutralize them. Sometimes programmers inherit bugs from the libraries they use in their own code. Sometimes bugs happen intermittently based on an unexpected combination of choices made by a particularly creative user. Not all bugs are so crippling that they stop an application from running (or even from compiling), and not all bugs are caused by incorrect code.

It's a fact of life, in even the most basic forms of programming, that code has bugs. Using GDB is one way to hunt them down and eliminate them. If they were easy to catch, they wouldn't be bugs. It's especially frustrating when code compiles but then reveals that there are bugs present, but that's how the trickiest of bugs work. Making that change causes the application to run as expected, with no more obvious bugs present. In this example, the whatis command on a variable gives you a clue that your alpha and beta variables are integers, which might jog your memory about printf syntax, making you realize that instead of %s in your printf statements, you must use the %d designator. This kind of introspection better informs you about not only what code is getting executed but how it's getting executed. An easy way to get to 11 quickly is to set a breakpoint that looks for a specific line number: To try some data introspection, restart your application by issuing the start command again and then proceed to line 11. Once your code is loaded into GDB, you can ask GDB about the data that the code has produced so far. The bug has been exposed several times in this article (spoiler: the wrong data type is being provided to printf), but assume for a moment that the solution remains unclear and that further investigation is required. so.6įrom this process, you can confirm that the crash didn't happen when the beta variable was being set but when the printf line was executed. Program received signal SIGSEGV, Segmentation fault.Ġx00007ffff71c0c0b in vfprintf ( ) from /lib64 /libc. Welcome to the communityġ4 printf ( "alpha is set to is %s \n", alpha ).If you're overwhelmed by the number of personal accounts you're trying to manage, or you're trying to keep your small business on track financially, GnuCash is freeware you should try.
#Gnucash account code series#
GnuCash is an ongoing project and this isn't the latest release, but the developers warn that the 2.3 series is not stable and is for testing only, so stick with this earlier version. And novice users will appreciate the wizard that walks you through the setup process. Fortunately, GnuCash has an excellent tutorial that outlines not only the program, but also financial terminology as well.
We found it a simple process to view spending reports, reconcile checking accounts, and other tasks.ĭespite the overall simplicity of using the program, the sheer number of terms and actions may require a dictionary for some people. At the top of the screen are various commands for actions, reports and tools. Selecting an entry displays further details in a larger pane.
Various holdings (anything from checking accounts, to CDs, stocks and any other form of investment) are listed in a tree along the left side. This freeware program's interface is bland but functional, and presents itself in a way that will be familiar to users who do their banking online. Although users with a solid grasp of financial management basics will get the most from this freeware program, GnuCash proved to be a capable tool for personal and small business accounting.
