Hello!
Sorry if it was discussed already but I can't find anything really
useful for me.
In current project I use lex & yacc and Makefile rules looks like:
cmake currently does not ship with bison and flex modules,
unfortunately. Here's a couple of mine.
--------------- FindFlex.cmake
# - Try to find Flex
# Once done this will define
#
# FLEX_FOUND - system has Flex
# FLEX_EXECUTABLE - path of the flex executable
# FLEX_VERSION - the version string, like "2.5.31"
#
FIND_PROGRAM(FLEX_EXECUTABLE NAMES flex flex.exe )
IF(FLEX_EXECUTABLE)
SET(FLEX_FOUND TRUE)
EXECUTE_PROCESS(COMMAND ${FLEX_EXECUTABLE} --version
OUTPUT_VARIABLE _FLEX_VERSION
)
string (REGEX MATCH "[0-9]+\\.[0-9]+\\.[0-9]+" FLEX_VERSION
"${_FLEX_VERSION}")
ENDIF(FLEX_EXECUTABLE)
IF(FLEX_FOUND)
IF(NOT Flex_FIND_QUIETLY)
MESSAGE(STATUS "Found Flex: ${FLEX_EXECUTABLE}")
ENDIF(NOT Flex_FIND_QUIETLY)
ELSE(FLEX_FOUND)
IF(Flex_FIND_REQUIRED)
MESSAGE(FATAL_ERROR "Could not find Flex")
ENDIF(Flex_FIND_REQUIRED)
ENDIF(FLEX_FOUND)
---------------------------
-------------------- FindBison.cmake
# - Try to find Bison
# Once done this will define
#
# BISON_FOUND - system has Bison
# BISON_EXECUTABLE - path of the bison executable
# BISON_VERSION - the version string, like "2.5.31"
#
FIND_PROGRAM(BISON_EXECUTABLE NAMES bison bison.exe )
IF(BISON_EXECUTABLE)
SET(BISON_FOUND TRUE)
EXECUTE_PROCESS(COMMAND ${BISON_EXECUTABLE} --version
OUTPUT_VARIABLE _BISON_VERSION
)
string (REGEX MATCH "[0-9]+\\.[0-9]+\\.[0-9]+" BISON_VERSION
"${_BISON_VERSION}")
ENDIF(BISON_EXECUTABLE)
IF(BISON_FOUND)
IF(NOT Bison_FIND_QUIETLY)
MESSAGE(STATUS "Found Bison: ${BISON_EXECUTABLE}")
ENDIF(NOT Bison_FIND_QUIETLY)
ELSE(BISON_FOUND)
IF(Bison_FIND_REQUIRED)
MESSAGE(FATAL_ERROR "Could not find Bison")
ENDIF(Bison_FIND_REQUIRED)
ENDIF(BISON_FOUND)
--------------------------
----------- Sample usage
FIND_PACKAGE( Flex REQUIRED)
FIND_PACKAGE( Bison REQUIRED)
#
# Create custom command for flex/lex (note the outputs)
#
ADD_CUSTOM_COMMAND(
SOURCE "${CMAKE_CURRENT_SOURCE_DIR}/grammar.lex"
COMMAND ${FLEX_EXECUTABLE}
ARGS -o"${CMAKE_CURRENT_BINARY_DIR}/lex.yy.c"
-Pmrl_yy -8 -CFe "${CMAKE_CURRENT_SOURCE_DIR}/grammar.lex"
TARGET miparser
OUTPUTS "${CMAKE_CURRENT_BINARY_DIR}/lex.yy.c"
)
#
# Create custom commands for bison/yacc (note the DEPENDS)
#
ADD_CUSTOM_COMMAND(
SOURCE "${CMAKE_CURRENT_SOURCE_DIR}/grammar.y"
COMMAND ${BISON_EXECUTABLE}
ARGS -l -pmrl_yy -o"${CMAKE_CURRENT_BINARY_DIR}/grammar.tab.cpp"
"${CMAKE_CURRENT_SOURCE_DIR}/grammar.y"
TARGET miparser
DEPENDS "${CMAKE_CURRENT_BINARY_DIR}/lex.yy.c"
OUTPUTS "${CMAKE_CURRENT_BINARY_DIR}/grammar.tab.cpp"
)
