| 136 .SH DESCRIPTION | |
| 137 .B lcov | |
| 138 is a graphical front\-end for GCC's coverage testing tool gcov. It collects | |
| 139 line, function and branch coverage data for multiple source files and creates | |
| 140 HTML pages containing the source code annotated with coverage information. | |
| 141 It also adds overview pages for easy navigation within the file structure. | |
| 142 | |
| 143 Use | |
| 144 .B lcov | |
| 145 to collect coverage data and | |
| 146 .B genhtml | |
| 147 to create HTML pages. Coverage data can either be collected from the | |
| 148 currently running Linux kernel or from a user space application. To do this, | |
| 149 you have to complete the following preparation steps: | |
| 150 | |
| 151 For Linux kernel coverage: | |
| 152 .RS | |
| 153 Follow the setup instructions for the gcov\-kernel infrastructure: | |
| 154 .I http://ltp.sourceforge.net/coverage/gcov.php | |

| 159 For user space application coverage: | |
| 160 .RS | |
| 161 Compile the application with GCC using the options | |
| 162 "\-fprofile\-arcs" and "\-ftest\-coverage". | |
| 163 .RE | |
| 164 | |
| 165 Please note that this man page refers to the output format of | |
| 166 .B lcov | |
| 167 as ".info file" or "tracefile" and that the output of GCOV | |
| 168 is called ".da file". | |

| 201 .RI "Use " directory | |
| 202 as base directory for relative paths. | |
| 203 | |
| 204 Use this option to specify the base directory of a build\-environment | |
| 205 when lcov produces error messages like: | |
| 206 | |
| 207 .RS | |
| 208 ERROR: could not read source file /home/user/project/subdir1/subdir2/subdir1/sub
dir2/file.c | |
| 209 .RE | |
| 210 | |
| 211 In this example, use /home/user/project as base directory. | |
| 212 | |
| 213 This option is required when using lcov on projects built with libtool or | |
| 214 similar build environments that work with a base directory, i.e. environments, | |
| 215 where the current working directory when invoking the compiler is not the same | |
| 216 directory in which the source code file is located. | |
| 217 | |
| 218 Note that this option will not work in environments where multiple base | |
| 219 directories are used. In that case repeat the lcov call for each base directory | |
| 220 while using the \-\-ignore\-errors option to prevent lcov from exiting when the | |
| 221 first source code file could not be found. This way you can get partial coverage | |
| 222 information for each base directory which can then be combined using the \-a | |
| 223 option. | |

| 231 Capture coverage data. | |
| 232 | |
| 233 By default captures the current kernel execution counts and writes the | |
| 234 resulting coverage data to the standard output. Use the \-\-directory | |
| 235 option to capture counts for a user space program. | |
| 236 | |
| 237 The result of the capture operation will be written to stdout or the tracefile | |
| 238 specified with \-o. | |

| 248 .RS | |
| 249 Specify whether to generate checksum data when writing tracefiles. | |
| 250 | |
| 251 Use \-\-checksum to enable checksum generation or \-\-no\-checksum to | |
| 252 disable it. Checksum generation is | |
| 253 .B disabled | |
| 254 by default. | |
| 255 | |
| 256 When checksum generation is enabled, a checksum will be generated for each | |
| 257 source code line and stored along with the coverage data. This checksum will | |
| 258 be used to prevent attempts to combine coverage data from different source | |
| 259 code versions. | |
| 260 | |
| 261 If you don't work with different source code versions, disable this option | |
| 262 to speed up coverage data processing and to reduce the size of tracefiles. | |

| 271 | |
| 272 Use \-\-compat\-libtool to enable libtool compatibility mode or \-\-no\-compat\-
libtool | |
| 273 to disable it. The libtool compatibility mode is | |
| 274 .B enabled | |
| 275 by default. | |
| 276 | |
| 277 When libtool compatibility mode is enabled, lcov will assume that the source | |
| 278 code relating to a .da file located in a directory named ".libs" can be | |
| 279 found in its parent directory. | |
| 280 | |
| 281 If you have directories named ".libs" in your build environment but don't use | |
| 282 libtool, disable this option to prevent problems when capturing coverage data. | |

| 303 | |
| 304 Use this option if you want to merge coverage data from different source code | |
| 305 levels of a program, e.g. when you have data taken from an older version | |
| 306 and want to combine it with data from a more current version. | |
| 307 .B lcov | |
| 308 will try to map source code lines between those versions and adjust the coverage | |
| 309 data respectively. | |
| 310 .I difffile | |
| 311 needs to be in unified format, i.e. it has to be created using the "\-u" option | |
| 312 of the | |
| 313 .B diff | |
| 314 tool. | |
| 315 | |
| 316 Note that lines which are not present in the old version will not be counted | |
| 317 as instrumented, therefore tracefiles resulting from this operation should | |
| 318 not be interpreted individually but together with other tracefiles taken | |
| 319 from the newer version. Also keep in mind that converted coverage data should | |
| 320 only be used for overview purposes as the process itself introduces a loss | |
| 321 of accuracy. | |
| 322 | |
| 323 The result of the diff operation will be written to stdout or the tracefile | |

| 583 Use this switch if you want to remove coverage data for a particular | |
| 584 set of files from a tracefile. Additional command line parameters will be | |
| 585 interpreted as shell wildcard patterns (note that they may need to be | |
| 586 escaped accordingly to prevent the shell from expanding them first). | |
| 587 Every file entry in | |
| 588 .I tracefile | |
| 589 which matches at least one of those patterns will be removed. | |
| 590 | |
| 591 The result of the remove operation will be written to stdout or the tracefile | |
