For example: 45 </p> 46 47 <div class="shell"> 48 <pre> 49 example.i:16: Warning 501: Overloaded declaration ignored. bar(double) 50 example.i:15: Warning 501: Previous declaration is bar(int) 51 </pre> 52 </div> 53 54 <p> 55 Typically, warning messages indicate non-fatal problems with the input 56 where the generated wrapper code will probably compile, but it may not 57 work like you expect. 58 </p> 59 60 <H2><a name="Warnings_suppression">19.2 Warning message suppression</a></H2> 61 62 63 <p> 64 All warning messages have a numeric code that is shown in the warning message itself. 65 To suppress the printing of a warning message, a number of techniques can be used. 66 First, you can run SWIG with the <tt>-w</tt> command line option. For example: 67 </p> 68 69 <div class="shell"> 70 <pre> 71 % swig -python -w501 example.i 72 % swig -python -w501,505,401 example.i 73 </pre> 74 </div> 75 76 <p> 77 Alternatively, warnings can be suppressed by inserting a special preprocessor pragma 78 into the input file: 79 </p> 80 81 <div class="code"> 82 <pre> 83 %module example 84 #pragma SWIG nowarn=501 85 #pragma SWIG nowarn=501,505,401 86 </pre> 87 </div> 88 89 <p> 90 Finally, code-generation warnings can be disabled on a declaration by declaration basis using 91 the <tt>%warnfilter</tt> directive. For example: 92 </p> 93 94 <div class="code"> 95 <pre> 96 %module example 97 %warnfilter(501) foo; 98 ... 99 int foo(int); 100 int foo(double); // Silently ignored. 101 </pre> 102 </div> 103 104 <p> 105 The <tt>%warnfilter</tt> directive has the same semantics as other declaration modifiers like 106 <tt>%rename</tt>, <tt>%ignore</tt> and <tt>%feature</tt>, see the 107 <a href="Customization.html#Customization_features">%feature directive</a> section. For example, if you wanted to 108 suppress a warning for a method in a class hierarchy, you could do this: 109 </p> 110 111 <div class="code"> 112 <pre> 113 %warnfilter(501) Object::foo; 114 class Object { 115 public: 116 int foo(int); 117 int foo(double); // Silently ignored 118 ... 119 }; 120 121 class Derived : public Object { 122 public: 123 int foo(int); 124 int foo(double); // Silently ignored 125 ... 126 }; 127 </pre> 128 </div> 129 130 <p> 131 Warnings can be suppressed for an entire class by supplying a class name. For example: 132 </p> 133 134 <div class="code"> 135 <pre> 136 %warnfilter(501) Object; 137 138 class Object { 139 public: 140 ... // All 501 warnings ignored in class 141 }; 142 </pre> 143 </div> 144 145 <p> 146 There is no option to suppress all SWIG warning messages. The warning messages are there 147 for a reason---to tell you that something may be <em>broken</em> in 148 your interface. Ignore the warning messages at your own peril. 149 </p> 150 151 152 <H2><a name="Warnings_nn4">19.3 Enabling extra warnings</a></H2> 153 154 155 <p> 156 Some warning messages are disabled by default and are generated only 157 to provide additional diagnostics. These warnings can be turned on using the 158 <tt>-Wextra</tt> option. For example: 159 </p> 160 161 <div class="shell"> 162 <pre> 163 % swig -Wextra -python example.i 164 </pre> 165 </div> 166 167 <p> 168 Preprocessor warning 202 ("Could not evaluate expression <em>expr</em>.") was 169 formally off by default and enabled by <tt>-Wextra</tt>, but since SWIG 4.1.0 170 this warning is on by default because suppressing it tends to hide genuine 171 problems. If you really don't want to see it, you can suppress it with 172 <tt>-w202</tt> or using <tt>%warnfilter</tt> as described below. Both will work 173 with older versions of SWIG too. 174 </p> 175 176 <p> 177 To selectively turn on extra warning messages, you can use the directives and options in the 178 previous section--simply add a "+" to all warning numbers. For example: 179 </p> 180 181 <div class="shell"> 182 <pre> 183 % swig -w+309,+452 example.i 184 </pre> 185 </div> 186 187 <p> 188 or in your interface file use either 189 </p> 190 191 <div class="code"> 192 <pre> 193 #pragma SWIG nowarn=+309,+452 194 </pre> 195 </div> 196 197 <p> 198 or 199 </p> 200 201 <div class="code"> 202 <pre> 203 %warnfilter(+309,+452) foo; 204 </pre> 205 </div> 206 207 <p> 208 Note: selective enabling of warnings with <tt>%warnfilter</tt> overrides any global settings you might have 209 made using <tt>-w</tt> or <tt>#pragma</tt>. 210 </p> 211 212 <p> 213 You can of course also enable all warnings and suppress a select few, for example: 214 </p> 215 216 <div class="shell"> 217 <pre> 218 % swig -Wextra -w309,452 example.i 219 </pre> 220 </div> 221 222 <p> 223 The warnings on the right take precedence over the warnings on the left, so in the above example <tt>-Wextra</tt> adds numerous warnings including 452, but then <tt>-w309,452</tt> overrides this and so 452 is suppressed. 224 </p> 225 226 <p> 227 If you would like all warnings to appear, regardless of the warning filters used, then use the <tt>-Wall</tt> option. 228 The <tt>-Wall</tt> option also turns on the extra warnings that <tt>-Wextra</tt> adds, however, it is subtely different. 229 When <tt>-Wall</tt> is used, it also disables all other warning filters, 230 that is, any warnings suppressed or added in <tt>%warnfilter</tt>, <tt>#pragma SWIG nowarn</tt> 231 or the <tt>-w</tt> option. 232 </p> 233 234 <H2><a name="Warnings_nn5">19.4 Issuing a warning message</a></H2> 235 236 237 <p> 238 Warning messages can be issued from an interface file using a number of directives. The 239 <tt>%warn</tt> directive is the most simple: 240 </p> 241 242 <div class="code"> 243 <pre> 244 %warn "900:This is your last warning!" 245 </pre> 246 </div> 247 248 <p> 249 All warning messages are optionally prefixed by the warning number to use. If you are generating 250 your own warnings, make sure you don't use numbers defined in the table at the end of this section. 251 </p> 252 253 <p> 254 The <tt>%ignorewarn</tt> directive is the same as <tt>%ignore</tt> except that it issues a 255 warning message whenever a matching declaration is found. For example: 256 </p> 257 258 <div class="code"> 259 <pre> 260 %ignorewarn("362:operator= ignored") operator=; 261 </pre> 262 </div> 263 264 <p> 265 Warning messages can be associated with typemaps using the 266 <tt>warning</tt> attribute of a typemap declaration. For example: 267 </p> 268 269 <div class="code"> 270 <pre> 271 %typemap(in, warning="901:You are really going to regret this usage of $1_type $1_name") blah * { 272 ... 273 } 274 </pre> 275 </div> 276 277 <p> 278 In this case, the warning message will be printed whenever the typemap is actually used and the <a href="Typemaps.html#Typemaps_special_variables">special variables</a> will be expanded as appropriate, for example: 279 </p> 280 281 <div class="shell"> 282 <pre> 283 example.i:23: Warning 901: You are really going to regret this usage of blah * self 284 example.i:24: Warning 901: You are really going to regret this usage of blah * stuff 285 </pre> 286 </div> 287 288 <H2><a name="Warnings_symbolic_symbols">19.5 Symbolic symbols</a></H2> 289 290 291 <p> 292 The <tt>swigwarn.swg</tt> file that is installed with SWIG contains symbol constants that could also be 293 used in <tt>%warnfilter</tt> and <tt>#pragma SWIG nowarn</tt>. 294 For example this file contains the following line: 295 </p> 296 297 <div class="code"> 298 <pre> 299 %define SWIGWARN_TYPE_UNDEFINED_CLASS 401 %enddef 300 </pre> 301 </div> 302 303 <p> 304 so <tt>SWIGWARN_TYPE_UNDEFINED_CLASS</tt> could be used instead of 401, for example: 305 </p> 306 307 <div class="code"> 308 <pre> 309 #pragma SWIG nowarn=SWIGWARN_TYPE_UNDEFINED_CLASS 310 </pre> 311 </div> 312 313 <p> 314 or 315 </p> 316 317 <div class="code"> 318 <pre> 319 %warnfilter(SWIGWARN_TYPE_UNDEFINED_CLASS) Foo; 320 </pre> 321 </div> 322 323 <H2><a name="Warnings_nn6">19.6 Commentary</a></H2> 324 325 326 <p> 327 The ability to suppress warning messages is really only provided for 328 advanced users and is not recommended in normal use. You are advised 329 to modify your interface to fix the problems highlighted by the warnings 330 wherever possible instead of suppressing warnings. 331 </p> 332 333 <p> 334 Certain types of SWIG problems are errors. These usually arise due to 335 parsing errors (bad syntax) or semantic problems for which there is 336 no obvious recovery. There is no mechanism for suppressing error 337 messages. 338 </p> 339 340 <H2><a name="Warnings_nn7">19.7 Warnings as errors</a></H2> 341 342 343 <p> 344 Warnings can be handled as errors by using the <tt>-Werror</tt> command line 345 option. This will cause SWIG to exit with a non successful exit code if a 346 warning is encountered. 347 </p> 348 349 <H2><a name="Warnings_nn8">19.8 Message output format</a></H2> 350 351 352 <p> 353 The output format for both warnings and errors can be selected for 354 integration with your favourite IDE/editor. Editors and IDEs can usually parse 355 error messages and if in the appropriate format will easily take you 356 directly to the source of the error. The standard format is used by 357 default except on Windows where the Microsoft format is used by default. 358 These can be overridden using command line options, for example: 359 </p> 360 361 <div class="shell"><pre> 362 $ swig -python -Fstandard example.i 363 example.i:4: Syntax error in input(1). 364 $ swig -python -Fmicrosoft example.i 365 example.i(4) : Syntax error in input(1). 366 </pre></div> 367 368 <H2><a name="Warnings_nn9">19.9 Warning number reference</a></H2> 369 370 371 <H3><a name="Warnings_nn10">19.9.1 Deprecated features (100-199)</a></H3> 372 373 374 <ul> 375 <li>101.
