LPC 1.4 Error 0012: Unable to load CURL

Hi. I have just install LPC 1.4 in RH 7. ./start_lpc works good but when trying to connect from client throws error:

Text:Error querying service discovery: Failed to initialize RsslRestClient. Text: </local/jenkins/workspace/RRT  LPC/OS/OL7-64/esdk/source/rtsdk/Cpp-C/Eta/Impl/Transport/rsslSocketTransportImpl.c:547> Error: 0012 Unable to load CURL.

I have correctly setup LD_LIBRARY_PATH as included in the start script and try also other locations but fails with same error.

    There should be a "libcurl.so" library within the LD_LIBRARY_PATH path. That should have execute permissions. If the library isn't found or has incorrect permissions, then it cannot be loaded. Be sure to have "LD_LIBRARY_PATH" exported in your environment.

    Another possibility is that the incorrect compiled version of libcurl.so is in your LD_LIBRARY_PATH. For example, a RHEL8 library is in the directory vs the RHEL7 version. The installer should have installed the correct library version.

    Hi. LD_LIBRARY_PATH is correct and libcurl.so have execute permissions. I set the debug option in cnf file and here is part of the log. I can see a "RSSL_SC_USAGE_ERROR" code:

    It should be like this. For example, libcurl.so is in the /opt/lpc/curl directory.

    [radmin@d4636649ed34 lpc]$ pwd
    /opt/lpc
    [radmin@d4636649ed34 lpc]$ export LD_LIBRARY_PATH=/opt/lpc/curl
    [radmin@d4636649ed34 lpc]$ echo $LD_LIBRARY_PATH

    You may use the ldd to verify the requried libraries are found properly. Then, use the strings command to verify the version of libcurl.so.

    Based on your response, I gather that you are still experiencing errors? Some questions:

    1. Are you using the startup script to execute the LPC 1.4 process?
    2. What major version of Linux are you using (Linux 7 or 8)?
    3. What version of OpenSSL is installed on your Linux?

    Dear
    @Jirapongse, the ldd comand on
    libcurl.so throws that libcrypto was expecting openssl 1.0.2, and I was working with 1.0.1. I just install openssl 1.0.2 and now is working fine.

    Thanks for your help.

    Hi, the problem was openssl 1.0.1. Update to 1.0.2 and works fine. Thank you.
