[CMake] flex/bison modules?

[André EBERSOLD]

Hello Juan,

Several years ago, I wrote some cmake rules to work with lex and yacc on
Linux and windows.

Hop it will help you.

Below the macro :


#
# here, I will put some macro
# for flex and yacc transformation
#
# Author   EBERSOLD Andre
# Created  6/7/2007
#
IF(UNIX)
    SET(LEXER "flex" CACHE STRING "flex parser")
    SET(BISON "bison" CACHE STRING "yacc parser")
ELSE(UNIX)
    SET(LEXER "c:\\tools\\bison\\flex.exe" CACHE STRING "flex parser")
    SET(BISON "c:\\tools\\bison\\bison.exe" CACHE STRING "yacc parser")
ENDIF(UNIX)

#
#
#
MACRO(LEXGEN file)

ADD_CUSTOM_COMMAND(SOURCE ${CMAKE_CURRENT_SOURCE_DIR}/${file}.l
        COMMAND ${LEXER}
        ARGS  -olds_lexer.c ${CMAKE_CURRENT_SOURCE_DIR}/${file}.l
#        TARGET ${CMAKE_CURRENT_BINARY_DIR}/${file}.c
        OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/${file}.c
        COMMENT "lex files")

SET_SOURCE_FILES_PROPERTIES(${CMAKE_CURRENT_BINARY_DIR}/${file}.c GENERATED)

ENDMACRO(LEXGEN file)

MACRO(BISONGEN file)
   ADD_CUSTOM_COMMAND(SOURCE ${CMAKE_CURRENT_SOURCE_DIR}/${file}.y
        COMMAND ${BISON}
        ARGS    -d ${CMAKE_CURRENT_SOURCE_DIR}/${file}.y --output=${file}.c
#        TARGET ${CMAKE_CURRENT_BINARY_DIR}/${file}.c
        OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/${file}.c
        COMMENT "yacc files")

        SET_SOURCE_FILES_PROPERTIES(${CMAKE_CURRENT_BINARY_DIR}/${file}.c
GENERATED)
ENDMACRO(BISONGEN file)



If you don't plan to use macro ... You can write  rules like this :

SET(LEXER "c:\\tools\\bison\\flex.exe" CACHE STRING "flex parser")
SET(BISON "c:\\tools\\bison\\bison.exe" CACHE STRING "yacc parser")
INCLUDE_DIRECTORIES(${CMAKE_CURRENT_BINARY_DIR})
INCLUDE_DIRECTORIES(${CMAKE_CURRENT_SOURCE_DIR})

ADD_CUSTOM_COMMAND(SOURCE ${CMAKE_CURRENT_SOURCE_DIR}/jumli_lexer.l
                   COMMAND ${LEXER}
                   ARGS -ojumli_lexer.c
${CMAKE_CURRENT_SOURCE_DIR}/jumli_lexer.l
                   TARGET ${CMAKE_CURRENT_BINARY_DIR}/jumli_lexer.c
                   OUTPUTS ${CMAKE_CURRENT_BINARY_DIR}/jumli_lexer.c
                  )
ADD_CUSTOM_COMMAND(SOURCE ${CMAKE_CURRENT_SOURCE_DIR}/jumli_parser.y
                   COMMAND ${BISON}
                   ARGS --output jumli_parser.c -d
${CMAKE_CURRENT_SOURCE_DIR}/jumli_parser.y
                   TARGET ${CMAKE_CURRENT_BINARY_DIR}/jumli_parser.c
                   OUTPUTS ${CMAKE_CURRENT_BINARY_DIR}/jumli_parser.c
                  )

SET_SOURCE_FILES_PROPERTIES(${CMAKE_CURRENT_BINARY_DIR}/jumli_parser.c
GENERATED)
SET_SOURCE_FILES_PROPERTIES(${CMAKE_CURRENT_BINARY_DIR}/jumli_lexer.c
GENERATED)
