[CMake] Problem when globbing files and using that OUTPUT variable between ADD_CUSTOM_COMMAND commands

2012-02-17 Thread NoRulez 
Hi,i have several ADD_CUSTOM_COMMAND commands with a specified target (let's say TARGET1).Between those commands I need to collect files and want to use those collected files in the next ADD_CUSTOM_COMMAND.How can i do that, because the following doesn't work as expected.ADD_CUSTOM_COMMAND(TARGET TARGET1 COMMAND SAMPLE_COMMAND ARGS ARGUMENTS WORKING_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY} COMMENT "Doing some stuff" VERBATIM)# HERE I NEED A CUSTOM COMMAND where the CUSTOM_FILES variable can be used in the next ADD_CUSTOM_COMMANDADD_CUSTOM_COMMAND(OUTPUT CUSTOM_FILES

 Hi,

 i have several ADD_CUSTOM_COMMAND commands with a specified target (let's
 say TARGET1).
 Between those commands I need to collect files and want to use those
 collected files in the next ADD_CUSTOM_COMMAND.
 How can i do that, because the following doesn't work as expected.

 ADD_CUSTOM_COMMAND(TARGET TARGET1
COMMAND SAMPLE_COMMAND ARGS ARGUMENTS
WORKING_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}
COMMENT Doing some stuff
VERBATIM)

may be you could do:

ADD_CUSTOM_COMMAND(TARGET TARGET1
   COMMAND SAMPLE_COMMAND ARGS ARGUMENTS
   COMMAND ${CMAKE_COMMAND} -DOutFile=fl.cmake -P
collectFiles.cmake
   COMMAND ${CMAKE_COMMAND} -DInFile=fl.cmake -P
doPostProcessing.cmake
   WORKING_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}
   COMMENT Doing some stuff
   VERBATIM)

the collectFiles step will do whatever you want and create the fl.cmake
file
which will be loaded by the second doPostProcessing in order to get
access to list of file in a pre-defined CMake var.

You can split this in separate add_custom_command but I don't see the need
in your example.


 # HERE I NEED A CUSTOM COMMAND where the CUSTOM_FILES variable can be used
 in the next ADD_CUSTOM_COMMAND
 ADD_CUSTOM_COMMAND(OUTPUT CUSTOM_FILES
COMMAND /usr/bin/find ARGS ${CUSTOM_PATH} -type f
COMMENT Find files
VERBATIM)

 ADD_CUSTOM_COMMAND(TARGET TARGET1
COMMAND SAMPLE_COMMAND ARGS ${CUSTOM_FILES}
WORKING_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}
COMMENT Doing some stuff
VERBATIM)

 ADD_CUSTOM_COMMAND(TARGET TARGET1
COMMAND SAMPLE_COMMAND ARGS ARGUMENTS
WORKING_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}
COMMENT Doing some stuff
VERBATIM)

 Thanks in advance

Re: [CMake] Problem when globbing files and using that OUTPUT variable between ADD_CUSTOM_COMMAND commands

2012-02-17 Thread Eric Noulard 
2012/2/17 noru...@me.com

 Is there no way to depend on an other custom command without using extra 
 files?

I don't think there is beside the fact that you can specify dependency
to a target (including custom target) or files using OUTPUT and DEPENDS options.

 It would be nice if i can pass OUTPUT and TARGET to ADD_CUSTOM_COMMAND.

You can (using OUTPUT and DEPENDS) your problem is you don't
know the output of your command **statically**.

 So i here is my problem in a more detail:
 I want to get a list of files from 
 ${CMAKE_RUNTIME_OUTPUT_DIR}/${PROJECT_NAME}.app where all files beginning 
 with ${PROJECT_NAME} would be excluded.

The result of this command is only known at build-time.
At build time the build tool (make, Visual Studio, etc...) is
running not CMake,
The objective of add_custom_ is to execute some commands **at
build-time** on behalf
of the build tool how would the build tool handle a CMake variable
while CMake is not even running ???

 After that I want to iterate over that list (foreach) and run 
 ADD_CUSTOM_COMMAND for each file.
 I see here no need for any extra files.

I think you are missing a point.
the ADD_CUSTOM_COMMAND processed by CMake when reading
CMakeLists.txt at CMake time
are ***TRANSLATED*** into build tool rules.

I think there is a need of an extra file because it's the only way to
communicate
build-time informations between several build tool rules (i.e.
derived from custom command).

The only way around I see would be for you to know ahead of build (at
CMake time)
the list of files you'll be processing.
