A scanner, sometimes +called a tokenizer, is a program which recognizes lexical patterns in +text. The flex program reads user-specified input files, or its standard +input if no file names are given, for a description of a scanner to +generate. The description is in the form of pairs of regular expressions +and C code, called rules. Flex generates a C source file named, +\"lex.yy.c\", which defines the function yylex(). The file \"lex.yy.c\" +can be compiled and linked to produce an executable. When the executable +is run, it analyzes its input for occurrences of text matching the +regular expressions for each rule. Whenever it finds a match, it +executes the corresponding C code.") + (license "BSD"))) diff --git a/distro/packages/patches/flex-bison-tests.patch b/distro/packages/patches/flex-bison-tests.patch new file mode 100644 index 0000000000..0f372f83bf --- /dev/null +++ b/distro/packages/patches/flex-bison-tests.patch @@ -0,0 +1,24 @@ +The `test-bison-yyl{loc,val}' tests fail with "conflicting types for +'testparse'" because `YYPARSE_PARAM' is undefined; work around that. + +--- flex-2.5.37/tests/test-bison-yylloc/main.c 2012-11-22 18:17:01.000000000 +0100 ++++ flex-2.5.37/tests/test-bison-yylloc/main.c 2012-11-22 18:17:07.000000000 +0100 +@@ -21,6 +21,7 @@ + * PURPOSE. + */ + ++#define YYPARSE_PARAM scanner + #include "parser.h" + #include "scanner.h" + + +--- flex-2.5.37/tests/test-bison-yylval/main.c 2012-11-22 18:17:42.000000000 +0100 ++++ flex-2.5.37/tests/test-bison-yylval/main.c 2012-11-22 18:17:49.000000000 +0100 +@@ -21,6 +21,7 @@ + * PURPOSE. + */ + ++#define YYPARSE_PARAM scanner + #include "parser.h" + #include "scanner.h" + |
