Hello,
I need some advices regarding FreeRDP & cmake.
I'd like to add a rule for generating files from Flex & Bison.
The parser.y and lexer.l files are located in libfreerdp/locale/
So I add that in the libfreerdp/locale/CMakeLists.txt :
<code>
if (WITH_SOME_VAR)
find_package(BISON REQUIRED)
find_package(FLEX REQUIRED)
bison_target(parser parser.y parser.c )
flex_target(scanner lexer.l lexer.c)
ADD_FLEX_BISON_DEPENDENCY(scanner parser)
set(${MODULE_PREFIX}_PARSER_SRCS
${BISON_parser_OUTPUTS}
${FLEX_lexer_OUTPUTS}
)
set(${MODULE_PREFIX}_SRCS ${${MODULE_PREFIX}_SRCS}
${${MODULE_PREFIX}_PARSER_SRCS})
endif()
</code>
But when I run "cmake -DWITH_SOME_VAR .", I've got this error message :
CMake Error at libfreerdp/CMakeLists.txt:293 (add_library):
Cannot find source file:
locale/parser.c
To me, it is normal that the parser.c file cannot be find (because it
have to be generated at compile time by bison) but how can I tell cmake
that this file will be generated later ?
For info, if I create a new project with CMakeLists.txt (see below) all
work fine (at least for the cmake generating part), so I think my
problem is my lack of knowledge of the FreeRDP cmake structure (and
cmake itself by the way).
Is someone can tell me what I do wrong ?
<code>
project(test)
# find required packages
find_package(FLEX REQUIRED)
find_package(BISON REQUIRED)
# create parser and scanner sources
bison_target(parser parser.y parser.c)
flex_target(scanner scanner.l scanner.c)
# probably the scanner depends on headers from the parser
add_flex_bison_dependency(scanner parser)
# define all sources here
set(lib_sources
a.c
b.c
${BISON_parser_OUTPUTS}
${FLEX_scanner_OUTPUTS})
# set up include directories
include_directories(
${CMAKE_CURRENT_SOURCE_DIR}
${CMAKE_CURRENT_BINARY_DIR})
# create the library
add_library(test ${lib_sources})
</code>
Regards,
Vincent.
