Looking at the Source Files. Simple Debugging

You can perform the following operations on source files:

• Tell the debugger where your sources are, if it cannot find them.
• Find out the name of the current source file.
• Switch to a different source file.
• List lines in a source file.
• Search within a source file.

DBX Mode

Following is an example that shows listing lines and using the / command to search for a string:

(idb) file

src/x_list.cxx

(idb) list 180:10

    180 main()

    181 {

    182     List<Node> nodeList;

    183

    184     // add entries to list

    185     //

>   186     IntNode* newNode = new IntNode(1);

    187     nodeList.append(newNode);   {static int somethingToReturnTo; somethingToReturnTo++; }

    188

    189     CompoundNode* cNode = new CompoundNode(12.345, 2);

(idb) /CompoundNode

    192     CompoundNode* cNode1 = new CompoundNode(3.1415, 7)

Aliases are shorthand forms of longer commands. This example shows using the W alias, which lists up to 20 lines around the current line. Note that a right bracket (>) marks the current line.

(idb) alias W

W       list $curline - 10:20

(idb) W

    176

    177

    178 //  The driver for this test

    179 //

    180 main()

    181 {

    182     List<Node> nodeList;

    183

    184     // add entries to list

    185     //

>   186     IntNode* newNode = new IntNode(1);

    187     nodeList.append(newNode);

    188

    189     CompoundNode* cNode = new CompoundNode(12.345, 2);

    190     nodeList.append(cNode);

    191

    192     nodeList.append(new IntNode(3));

    193

    194     IntNode* newNode2 = new IntNode(4);

    195     nodeList.append(newNode2);

GDB Mode

Use info source, info line, and list commands for looking at source files:

(idb) info source

Current source file is src/x_list.cxx

(idb) list 180,+10

180 main()

181 {

182     List<Node> nodeList;

183

184     // add entries to list

185     //

186     IntNode* newNode = new IntNode(1);

187     nodeList.append(newNode);   {static int somethingToReturnTo; somethingToReturnTo++; }

188

189     CompoundNode* cNode = new CompoundNode(12.345, 2);

(idb) forward-search CompoundNode

192     CompoundNode* cNode1 = new CompoundNode(3.1415, 7);
