Hi,

I found the following Macro after some research:


macro(ADD_FRAMEWORK fwname appname)
    find_library(FRAMEWORK_${fwname}
        NAMES ${fwname}
        PATHS ${CMAKE_OSX_SYSROOT}/System/Library
        PATH_SUFFIXES Frameworks
        NO_DEFAULT_PATH)
    if( ${FRAMEWORK_${fwname}} STREQUAL FRAMEWORK_${fwname}-NOTFOUND)
        MESSAGE(ERROR ": Framework ${fwname} not found")
    else()
        TARGET_LINK_LIBRARIES(${appname} ${FRAMEWORK_${fwname}})

MESSAGE(STATUS "Framework ${fwname} found at${FRAMEWORK_${fwname}}")

    endif()
endmacro(ADD_FRAMEWORK)

after the TARGET_LINK_LIBRARIES (sic!)

add_framework(Foundation Application)
add_framework(Security Application)


hth

Hi, Sebastian.
I would like to have a look at that CMake file :)
Thanks.

    Hi folks,

    I found the problem and thus a solution.
    The main issue was that I generated the project with CMake and
    therefore the framework paths where missing.
    I came up with a solution adding the frameworks programmatically
    using a CMake-macro which made linking to libz and curl possible.
    The iOSSimulator project is running as expected loading obj files
    from a HTTP url.
    Finally!

    If anyone is interested I can contribute the CMake file (Sorry I
    simpy hate using pre-baked Solution/XCode files etc.)


    I'm sure I will be back with further questions ;-)
    Thanks for the support, especially to Stephan.

    cheers
    Sebastian

    I'm still struggling with the issue. Could you (or someone
    else) try to link the curl plugin in a iOS-Simulator project
    and check if the linker complains?
    As said before I'm not familiar with the MacOS/iOS platform, so
    I don't know the tools to check the dependencies neither I know
    which SSL library could be appropriate to link.


    All I can say is that it's working for me. I don't use any
    SSL-stuff with libcurl. I am just using the osgdb_curl plugin
    and the libcurl.a Have a look at the Present3D-Control-app how
    the linking etc is setup, maybe there are some differences.

    I don't use SSL directly. I'm simply linking the curl.a delivered
    at the github page you pointed me to, which gives me the linker
    error.
    Thanks for the hint, I'll check the Present3D app, maybe I can
    locate the correct libraries there.


    And please: Post the exact error-messages, the complete output
    of the linking-stage.

    Ok, I will try to.


    cheers,

    Stephan
