Re: [EXTERNAL] Re: Using function from OOT in another OOT

Michael,

Thank you for the response.  Here is what I ended up doing:

If I have gr-myoot that I want to reference from gr-anotheroot

In gr-anotheroot/cmake/modules, create FindMyoot.cmake, which should look something like:

########################################################

find_package(PkgConfig)
pkg_check_modules(PC_GNURADIO_RUNTIME gnuradio-runtime)

find_path(MYOOT_INCLUDE_DIR myoot/one_of_the_header_files.h
          HINTS ${PC_GNURADIO_RUNTIME_INCLUDEDIR} ${PC_GNURADIO_RUNTIME_INCLUDE_DIRS}
          PATH_SUFFIXES myoot )

find_library(MYOOT_LIBRARY NAMES gnuradio-myoot
             HINTS ${PC_GNURADIO_RUNTIME_LIBDIR} ${PC_GNURADIO_RUNTIME_LIBRARY_DIRS} )

include(FindPackageHandleStandardArgs)
# handle the QUIETLY and REQUIRED arguments and set MYOOT_FOUND to TRUE
# if all listed variables are TRUE
find_package_handle_standard_args(Myoot  DEFAULT_MSG
                                  MYOOT_LIBRARY MYOOT_INCLUDE_DIR)

mark_as_advanced(MYOOT_INCLUDE_DIR MYOOT_LIBRARY )

set(MYOOT_LIBRARIES ${MYOOT_LIBRARY} )
set(MYOOT_INCLUDE_DIRS ${MYOOT_INCLUDE_DIR} )
########################################################

I'm sure there are better ways to do this, but this did the trick quick and dirty.  It looks like some other oots have .pc files installed which help with the process, but that doesn't look to be standard.

Hi Josh - I don't think there's a standard way to do this. -Most- OOTs install cmake scripts that can be used to "find" them, if you can determine the correct "find" name (might be "gr-OOT" or just "OOT", where 'OOT' is the name of the OOT module). Once found, you can then use either the target or returned variables (OOT_INCLUDE_DIRS, OOT_LIBRARIES most likely) to find the API and link against the ABI. Nothing special, but generic enough that it should work on different OSs & GR installs. Hope this is useful! - MLD

Is there a prescribed method for including functions from one OOT in another OOT (c++ code)?

I could probably figure out how to do it in cmake, but is there some magical cmake find functions that already exist for OOTs to set the INCLUDE and LIBRARY variables relative to the GR prefix installation?

Thanks,

Josh
