To build picrin, you need some build tools installed on your platform.

- cmake (>= 2.8)

- cmake (>= 2.6)

- git

# - Find flex executable and provides a macro to generate custom build rules
|
||||
#
|
||||
# The module defines the following variables:
|
||||
# FLEX_FOUND - true is flex executable is found
|
||||
# FLEX_EXECUTABLE - the path to the flex executable
|
||||
# FLEX_VERSION - the version of flex
|
||||
# FLEX_LIBRARIES - The flex libraries
|
||||
#
|
||||
# The minimum required version of flex can be specified using the
|
||||
# standard syntax, e.g. FIND_PACKAGE(FLEX 2.5.13)
|
||||
#
|
||||
#
|
||||
# If flex is found on the system, the module provides the macro:
|
||||
# FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>])
|
||||
# which creates a custom command to generate the <FlexOutput> file from
|
||||
# the <FlexInput> file. If COMPILE_FLAGS option is specified, the next
|
||||
# parameter is added to the flex command line. Name is an alias used to
|
||||
# get details of this custom command. Indeed the macro defines the
|
||||
# following variables:
|
||||
# FLEX_${Name}_DEFINED - true is the macro ran successfully
|
||||
# FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an
|
||||
# alias for FlexOutput
|
||||
# FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput}
|
||||
#
|
||||
# Flex scanners oftenly use tokens defined by Bison: the code generated
|
||||
# by Flex depends of the header generated by Bison. This module also
|
||||
# defines a macro:
|
||||
# ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget)
|
||||
# which adds the required dependency between a scanner and a parser
|
||||
# where <FlexTarget> and <BisonTarget> are the first parameters of
|
||||
# respectively FLEX_TARGET and BISON_TARGET macros.
|
||||
#
|
||||
# ====================================================================
|
||||
# Example:
|
||||
#
|
||||
# find_package(BISON)
|
||||
# find_package(FLEX)
|
||||
#
|
||||
# BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp
|
||||
# FLEX_TARGET(MyScanner lexer.l ${CMAKE_CURRENT_BIANRY_DIR}/lexer.cpp)
|
||||
# ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser)
|
||||
#
|
||||
# include_directories(${CMAKE_CURRENT_BINARY_DIR})
|
||||
# add_executable(Foo
|
||||
# Foo.cc
|
||||
# ${BISON_MyParser_OUTPUTS}
|
||||
# ${FLEX_MyScanner_OUTPUTS}
|
||||
