  12 Specifying program arguments, working directory, environment variables</h1>
  13 Choose <i>Execution|Arguments</i> to open a dialog where you can set program
  14 arguments, the working directory for your program, and environment variables.
  15 <h2>
  16 <a NAME="PgmArgs"></a>Program Arguments</h2>
  17 In the top edit box enter the arguments that shall be passed on to your
  18 program. Next time the program is started, the new arguments will be used.
  19 <h2>
  20 <a NAME="WorkingDir"></a>Working directory</h2>
  21 In the edit box below you can specify the working directory for your program.
  22 Your program will use the new directory only when it is run the next time.
  23 <p>The working directory also applies to gdb itself! The directory that
  24 you specify will be passed to gdb immediately, i.e. gdb will work with
  25 the new setting as soon as you press <i>OK</i>. This can influence whether
  26 source code files are found.
  27 <h2>
  28 <a NAME="Environment"></a>Environment variables</h2>
  29 In the environment variables section type in an expression of the form
  30 <tt>VARIABLE=value</tt>
  31 to set the environment variable <tt>VARIABLE</tt> to the value <tt>value</tt>,
  32 and click <i>Modify</i>. To remove a variable, select it from the list
  33 below and click <i>Remove</i>. To change the value, edit the value in the
  34 edit field and click <i>Modify</i>. If you change the name of the variable
  35 and click <i>Modify</i>, you add a new variable! The new environment variables
  36 will be used by your program the next time it is run.
  37 <p>An important environment variable to set if you are using glibc2 on
  38 Linux is <tt>LD_BIND_NOW</tt>. It is very important that you set this variable
  39 to <tt>1</tt> for all your debugging sessions. If it is not set, gdb cannot
  40 step into and out of system functions that are imported from the shared
  41 <tt>libc</tt>
  42 and other libraries.
