GDB allows you to do things like run the program up to a certain point then stop and print out the values of certain variables at that point, or step through the program one line at a time and print out the values of each variable after executing each line. GDB uses a simple command line interface. How it works?

Setting breakpoints A breakpoint is like a stop sign in your code -- whenever gdb gets to a breakpoint it halts execution of your program and allows you to examine it. To set breakpoints, type "break [filename]:[linenumber]". For example, if you wanted to set a breakpoint at line 55 of main.

The GNU gcc compiler is one of the most widely used C/C++ compilers in the world. ... The GNU compilers are highly optimizing compilers that support both the C and C++ languages. The GNU C compiler (gcc) supports the C language, while the GNU C++ compiler (G++) supports the C++ language.

Programming language and coding style Linux is written in a special C programming language supported by GCC, a compiler that extends in many ways the C standard, for example using inline sections of code written in the assembly language (in GCC's "AT&T-style" syntax) of the target architecture.

All globally initialised values are stored in . data segment . i.e. initialised data segment and uninitialised values are stored in bss and compiler initialise those uninitiated values to zero automatically in bss. Then why data segment is separated as .

GTK is entirely written in C and the GTK+ software that we commonly use in Linux are also written in C. The desktop managers, such as GENOME and XFCE, also are built using GTK. There are several language bindings available for GTK, such as the following: GTK with Python binding is called PyGTK.

gchar , used in gtk, is a glib type just a typedef to a char , so you're done already. ... The code you're showing passes an uninitialized char pointer to this function... So either that is your problem, or you are not showing your actual code, which means no one can help you.

It is statically linked against libstdc++ and libgcc, no other lib is used. It is a cpu and memory intensive non-parallel process (a mesh edition operation, lots of news and deletes and queries to data structures involved). The problem is not start-up time, the whole process is painfully slow.
