Failed to load shared library on RT target device.

I am using 7030 RT target. When I use Call Library Function Node with specified DLL library the application is working properly on Windows target. When I try to download the application on RT target PCI 7030 I get the following error messages: Failed to download useDLL.vi. Failed to load shared library EasyDLL.dll on RT target device. Because the application (attached to the question) is distributed with NI product I would suppose it is written OK. I would like to know what restrictions are imposed on DLL libraries which should be targeted on PCI 7030 RT target. Why the application useDLL.vi with EasyDLL.dll can't be loaded on PCI 7030? Does it mean that Call Library Function Nodes are not compatibel with PCI
7030 target?! Thank you for any explanation.

OK I downloaded your files and tried them with a PXI real time controller and the error you mentioned happened for me as well. After digging for awhile, here's the best explanation I could find:
1 - useDLL is calling other DLLs that are failing to download
2 - useDLL is accessing some of the Win API that is not supported by the RT OS.

  • CRIO Fails to Load Shared Library

    All,
    I'm getting an odd error every other time I tried to load my code onto a cRIO in the dev environment.
    Deploying NI_AALPro.lvlib:Linear Fit (LS).viNI_AALPro.lvlib:Linear Fit (LS).vi loaded with errors on the target and was closed.
    LabVIEW:  Failed to load shared library lvanlys.*:LinFit_head:C on RT target device.
    This VI works the first time, and then fails to run the second time you hit run.
    If I reboot the device this corrects the problem, but I have to say this bug costs me quite a lot of time.
    Regards,

    xkenneth,
    Did that solve your problem? If so, is it reproducible with a small project?

  • Failed to load shared library

    I am getting a "Failed to load shared library myDLL.dll:myFunction:C on RT Target Device" error when attempting to deploy a VI which contains a call to myDLL on a RT PXI.  If I open the VI with the Call Library Function Node and simply reselect myDLL within the Library name or Path box and save the VI, it will then deploy without error.  This continues to work until I start changing the VI at which point I attempt to deploy the VI again and get the failed to load error.  Once again I open the VI, reselect myDLL, save, and the failed to deploy error goes away.
    Does anyone have any ideas about whats going on here?
    Thanks in advance

    Hi Bob,
    Thanks for responding.  I am running LabVIEW 8.5 and running on an 8106 Embedded Controller.  Unfortunately, I cannot post my DLL however, I did some troubleshooting and found that the issue seems to be that myDLL calls another one of my DLLs which doesn't seem to be loaded onto the RT box.  If I deploy and run a VI which calls this second DLL and then run my original VI, it deploys without issue.  I guess I can understand why it didn't work in first place, since the 2nd DLL is not called from any VI and only called from myDLL, however I don't understand why simply opening the VI which contains the call to myDLL and reselecting it fixes the problem.  Also I have run the DLL thru the 8.5 DLL checker and it says that the DLL is OK, in fact the DLL checker new that myDLL had a dependency on the second DLL.  Is there something that I can do other than pre-deploy the second DLL to the RT box to get around this issue?
    Thanks again,

  • RealTime - Failed to load shared library

    Hi everyone,
    I'm working with the cRIO 9074 system and programmed a ANC application with LabView. Yesterday I tested my application the first time but it didn't work as expected. Because of my testing- and developing-place are different I have to carry the cRIO-System and my laptop between them. So I just disconneted the powersupply and the networkcable. Then 10min later I tried testing again but I got an error. Today in the morning I got the same error like yesterday, which is the following one:
    "Failed to load shared library AdaptivFilter. Ensure that the library is present on the RT target. Use MAX [...]"
    I reinstalled the NI software (more than once) how I was adviced with MAX but it didn't fix the problem, maybe the AdaptivFilters-library was not included.
    In the project-explorer a library called "NI_AdaptivFilter.lvlib" is included and I also found the path of the file on my harddrive.
    It drives my nuts that it worked and than 10min later it doesn't.
    I hope you could help me, thanks.

    这个错误是因为RT系统启动部署时缺失库文件或者加载库文件失败导致的。
    库文件加载失败原因有很多，而且就算把库文件重新添加进去可能也不能解决问题。建议你重装sbRIO 9636的RT系统，RT重装系统很快，10分钟就能完成。
    在MAX里面远程系统下找到你的9636，右键选择格式化。格式化完成后展开9636，右键软件选择更改删除软件，此时把软件再重新装进去就可以了。

  • DBD: Error while trying to load the transport provider for odbc. Failed to load the library. System error: The specified module could not be found.

    Hello Everyone,
    We are getting an error while trying to create an Universe via Microsoft -> MS Analysis Services 2014 -> OLEDB for OLAP Provider under Connection in UDT -"DBD: Error while trying to load the transport provider for odbc. Failed to load the library. System error: The specified module could not be found."  We have installed BI 4.1 SP05 in our system. As per earlier posts in scn in BO XI 3.x this issue used to be for improper installation of Integration KIT but in our scenarion Integration KIT is within the BO 4.1 package so no seperate installation is required. Moreover I have checked whether all the driver is present under file: "C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\dataAccess\connectionServer\drivers" and seems everything is fine. But still I am getting this error. One important point is we could use IDT because in IDT still we don't have option to connect with 'Microsoft Analysis Services - 2014 (XMLA)' as we are using Microsoft Analysis Services 2014 version.
    Kindly help if anyone has faced the same problem with SAP BO 4.1.
    Thanks and Best Regards,

  • Failed to load ODBC library symbol: /export/home/odbc/ODBC60/lib/libodbc.so

    I've been trying to create a database link from a MySQL database to Oracle using the Oracle dg4odbc gateway. I downloaded and installed DataDirect's ODBC package which includes mysql ODBC library (ddmysql24.so) and a generic ODBC libary (libodbc.so). After creating the DSN in odbc.ini, I tested it and it can connect to the mysql database. Then I created the init{SID}.ora file in hs/admin directory, added dg4odbc lines in the listener.ora, and added lines in tnsnames.ora. Then I tnspinged the new SID with success. Finally, I created the database link. However, when I tried to access the database, I got the ORA-28500 error. In the trace log, I found the following:

    on which platform did you install DG4ODBC? On a 64bit? In this case did you install the 64bit DD ODBC driver?
    What is the output of: file dg4odbc
    and: file /export/home/odbc/ODBC60/lib/libodbc.so
    can you also please clarify your statement: .. and a generic ODBC libary (libodbc.so). Datadirect ODBC drivers come with their own driver manager ... and you have to use their driver manager with their drivers.

    Dave,
    Please close Organizer and delete the folder Organizer inside your user folder @ path: C:\Documents and Settings\<username>\Application Data\Adobe\Photoshop Elements\6.0\Organizer.
    This would delete your APD preferences. If relaunch doesnot fix the problem, remove your card and restart your system and try again. Let me know if this works.

  • Loading shared library failed: Reports fatal: libgcc_s.so.1 : open failed

    Hi,
    I am developing a shared library in solaris. While loading the shared library it reports "ld.so.1: tn-tipc-config-bin: fatal: libgcc_s.so.1: open failed: No such file or directory". I noticed that libgcc_so.1 is available at /usr/sfw/lib. But this library is missing in some solaris build/install configuration. I want my library to loaded in any solaris system. So I want to reduce dependency over libgcc_s.so.1. By looking at the objdump of my shared library, I found that references to
    __register_frame_info and __deregister_frame_info which are provided by libgcc_s.so.1. Looks like these references are added by gccfss compiler since I dont call these functions in my code. Please suggest a method to remove reference for these functions.
    Thanks
    Shankar

    If you don't want to bring libraries your app depends on with you, the only choice you have is linking statically. It is a very bad idea to manually "detach" compiler-supplied library from the application unless you know exactly what you are doing. Even if your library does not call anything directly, initialization routines inserted by compiler may need routines from that library (just as an example).

Maybe you are looking for
