Dynamic Linking Error: ... ***.so: undefined symbol: entropy_func - Please help with a problem

[Ob1To]

I'm very new to node.js and all and was assign with a task. I have been using a lib so far like this:

function initLibrary() {
    MyLibrary = ffi.Library(path.join(__dirname, 'app/libs/libpcloudcc_lib'), {
        'psync_set_software_string': ['void', ['char *']],
        'get_token': ['string', []],
    });
}

but now I have been provided with a new lib for FB integration. They are 2 .so files and the one that I will use depends on another. I've searched so far and found that issue where you are explaining something similar - #80

My new .so files are pRJF.so, libcurl.so. Initially I've done something like this:

FbLib = ffi.Library(path.join(__dirname, 'app/libs/pRJF'), {
        'fb_authorize': ['char *', ['pointer']],
        'fb_login': ['int', ['char*', 'char **']]
    });

but I've received "App threw an error during load

Error: Dynamic Linking Error: /home/osboxes/Desktop/electron-app/app/libs/pRJF.so: undefined symbol: entropy_func

I guess these symbols are in the libcurl.so that I've done nothing so far with, just paste in the same lib folder with the others. I've tried to do something like that:

var RTLD_NOW = ffi.DynamicLibrary.FLAGS.RTLD_NOW;
    var RTLD_GLOBAL = ffi.DynamicLibrary.FLAGS.RTLD_GLOBAL;
    var mode = RTLD_NOW | RTLD_GLOBAL;
    var libCurl = ffi.DynamicLibrary(path.join(__dirname, 'app/libs/libcurl') + ffi.LIB_EXT, mode);

Again unsuccessfully, throwing the same error. The code though execute correct before the FbLib = ffi.Library(path.join(__dirname, 'app/libs/pRJF')...

Also I have tried to pass the libCurl as a 3rd parameter to the ffi.Library() function. once again with the same error:

FbLib = ffi.Library(path.join(__dirname, 'app/libs/pRJF'), {

        'fb_authorize': ['char *', ['pointer']],

        'fb_login': ['int', ['char*', 'char **']]
    }, libCurl);

Please help me because I'm on a verge of nervous breakdown, thank you!

Maybe you can try:

• windows
  copy your dll to C:\Windows\System32
• linux

vi /etc/ld.so.conf

add path where your .so in to this file

then

ldconfig

---

or

copy your .so to /usr/lib64
