Golang SDK - libappdynamics.so: cannot open shared object file

Golang SDK - libappdynamics.so: cannot open shared object file

 I've build a simple Golang application and have packaged it inside Docker, building off of the image '

busybox:ubuntu-14.04'

 

When I run the built app I get this error:

 

/usr/local/bin # ./golang-example-app
./golang-example-app: error while loading shared libraries: libappdynamics.so: cannot open shared object file: No such file or directory

 

Trying to fix it, I copied the AppDynamics Golang SDK folder underneath /usr/local/bin:

 

/usr/local/bin # ls -al
total 2432
drwxr-xr-x 4 root root 4096 Nov 22 15:03 .
drwxr-xr-x 6 root root 4096 Nov 22 15:03 ..

drwxr-xr-x 3 root root 4096 Nov 22 14:58 sdk_lib

 

 

I still get this error when running.

 

Do I need to "install" the 'libappdynamics.so' file in a certain location so it can be found by the Golang app?

Re: Golang SDK - libappdynamics.so: cannot open shared object file

Hi David,

 

You don't want to have appdynamics/ directory in /usr/local/bin/.

 

Try moving your golang-example-app in to the appdynamics/ directory and running it there.

 

In your specific case:

 

mv -v /usr/local/bin/golang-example-app /usr/local/bin/appdynamics/;
mv -v /usr/local/bin/appdynamics /;  # keep bin/ tidy.
cd /appdynamics; ./golang-example-app;
