error while loading shared libraries: libcrypto.so.1.0.0

[DougFerguson]

I have application written in C and I have added some message digest functions using openssl and libcrypto. I have linked the library in the Eclipse project via "-lcrypto" and "#include <openssl/evp.h>" in the C file. The application builds fine. However when I deploy and start the application on the cRIO, I am getting the following error at launch:

"error while loading shared libraries: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory"

I see that my cRIO has libcrypto.so.1.0.2 located in /usr/bin/

I assume I have some version issue. I would have thought 1.0.2 would be enough, does my application specifically call 1.0.0 without me explicitly calling it?

admin@NI-cRIO-9030-01C59BCD:/usr/lib/x86_64-linux-gnu/nisysapi# opkg info openssl

Ok, so it looks like my includes in Eclipse points to C:\build\17.0\lib\, which has libcrypto.so.1.0.0.

My cRIO feed is from 18.5, libcrypto.so.1.0.0 is not in //lib. I did find it here /usr/lib/libcrypto.so.1.0.2 Is this a linking/path issue?

Edit:

I tried creating a symbolic link and now I get this...

admin@NI-cRIO-9030-01C59BCD:/usr/lib# ln -s /usr/lib/libcrypto.so.1.0.2 /lib/libcrypto.so.1.0.0
admin@NI-cRIO-9030-01C59BCD:/usr/lib# /usr/local/bin/app
/usr/local/bin/app: /lib/libcrypto.so.1.0.0: version `OPENSSL_1.0.0' not found (required by /usr/local/bin/app)

Which looks like I need to either install openssl1.0.0 on the cRIO or somehow load openssl1.0.2 on my PC and include in the project build?

Edit:

I downgraded to 2017 drivers and now I have this:

Seems like I am closer with now having "libcrypto.so.1.0.0" but something still wants OpenSSL 1.0.0. Looks like I have some mismatch.

I am seeing that NI has moved and Linux RT developement from Eclipse (<2017) to Visual Studio. IF there is some package issue in NI's feeds for OpenSSL that is causing this issue, do I need to move to VS?

Hey Doug,

Can you rule out any search path issues with ldd? You can install it with opkg (I think the package is literally just ldd) and try running it on your application with and without the -v flag. That should give you an idea of what's missing and where it is looking for linked dependencies. 

Admittedly might just point at OpenSSL as you've already noted, but it's a good check to make.

I wanted to try calling openssl directly form the command line:

 I was able to get the same type of error and resolved ir by installing 'openssl-dev'.

However I can't resolve the same error when called by my application...

At this point I think the 2017 feed and library link in Eclipse is the root of the issue, but I don't see a solution to this. Any help would be appreciated. I am dead in the water on this topic.
