missing http_lib.lib library from cc3100sdk_1.2.0

Part Number: CC3100BOOST
Other Parts Discussed in Thread: CC3100SDK, MSP430F5529, CC3100,

Tool/software: Code Composer Studio

Hi. I am running ccs7 on windows 7 with cc3100sdk_1.2.0 and trying to import the http_client example from the msp430f5529lp platform examples. When I compile the code, I get a "cannot find file http_lib.lib" error. I am able to import and compile the getting_started_with_wlan_station.

Hardware is msp430f5529 launchpad and cc3100 booster.

Should this file be in the sdk. I have searched my hard drive and did not find this file present so I have nothing to point the linker to. Without this file, I get unresolved symbol errors (HTTPCli_sendRequest, HTTPCli_readResponseBody, etc).

The file search path in the properties msp430 linker indicates that http_lib.lib should be an included library.

Does anyone have any suggestions on how to proceed?

Thanks

    Hi Nick,

    It looks like the pre-built http_lib.lib is missing from the most recent CC3100 SDK, so you will have to import the CCS project, build the library, and link it to your http_client example.

    1. Import the http_lib project into CCS from <cc3100-sdk>\platform\msp430f5529lp\library_project_ccs\http_lib

    2. Build the http_lib project with the most recent MSP430 compiler or whatever MSP430 compiler you are using wit the http_client example.

    3. In the http_client example Properties, go to Build-> MSP430 Linker -> File Search Path and change the old http_lib path ("${CC3100_SDK_ROOT}/platform/msp430f5529lp/library_project_ccs/http_lib/Debug") to your newly built library ("${WORKSPACE_LOC}/http_lib/Debug").


    If you rebuild the example again and get an error about the data memory model, you may have to go back to the http_lib project properties and change Build -> MSP430 Compiler -> Processor Options -> Specify the data memory model -> restricted. Then rebuild both the library and the example again.

    Best regards,
    Sarah

    Sorry I can't be of much help here. I would suggesting opening a new thread with this question. I did notice that your directive -i"C:/TI/ccsv6/ccs_base/msp430/lib/5xx_6xx_FRxx" refers to the FRAM version of this processor. Maybe a configuration issue is causing the llibmath.a conflict?

    Good luck!

    Alternatively you could find the respective files in CC3100SDK_1.2.0/cc3100-sdk/netapps directory
