On Ubuntu, I have a C++ app in Eclipse. The application compiles fine and I can run the app from the command line.
But when I try to debug it or run it with Eclipse, the error :
"Cannot open shared object file: No such file or directory" is thrown on a shared library.
I've set LD_LIBRARY_PATH in my bashrc file and also set an LD_LIBRARY_PATH environment variable in both the Run Configuration and Debug Configuration to :
/home/behlingb/Documents/api_libs/FileGDB_API/lib
What else am I missing here to get Eclipse to run this?
UPDATE
There is only one shared object file this application requires, and that file is from a 3rd party API download. I just found that if I place the shared object inside the directory the executable is in, it will debug in Eclipse. Is there a way to specify a different directory so I dont have to copy the file for every project?
I'm using the Kepler version of Eclipse.
- In Eclipse click on Run then Debug Configurations
- Click on the Environment Tab
- Click on New
- Add LD_LIBRARY_PATH and set its value to the directory containing the library
- restart Eclipse
you can use strace utility (and then grep for open and/or stat calls) to get list of .so files required to run smth, then use locate (or find among packages) to find out the actual placement of required lib
According to what @zuafi suggested , you do not have to grep for the libraries and `locate' to find them.
Instead save strace's output to a file:
strace -o my_output_file.txt /path/to/my_executable_file
then open the file, where you can see
open("/a/path/to/some/library.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
scroll down those lines until you hit
open("/real/path/to/some/library.so", O_RDONLY|O_CLOEXEC) = 3 (any value here)
this means before finding /real/path/to/some/library.so there have been several trials to find library.so in different paths. but finally the library has been found in /real/path/to/some/.
Just copy and paste this into your Eclipse!
If you have set LD_LIBRARY_PATH and it doesn't work. Close Eclipes and run it from command terminal. I accidentally found that this could make it work. Not sure about the reason, but probably have something to do with Eclipes initialization.
This is valid with Eclipse Kepler (I have not looked into older versions). To enable the debugger to load your shared libraries, trying to set LD_LIBRARY_PATH will fail. However the CDT plugin provides a Shared Libraries list for this purpose
Run menu -> Debug Configurations ...
then in the configuration dialog
C/C++ Application -> your project -> Debugger tab -> Shared Libraries tab
