SNOPT 7.4 library cannot be loaded #11

Hi @darioizzo,

I am trying to use Snopt 7.4 (compiled from source) with snopt-interface commit 76b166e as mentioned in the README file. However I get a run-time error message that is quite similar to the one encountered in Issue #2:

ValueError:
function: evolve_version
where: /home/conda/feedstock_root/build_artifacts/pygmo_plugins_nonfree_1549017917386/work/include/pagmo_plugins_nonfree/snopt7.hpp, 766
what:
An error occurred while loading the snopt7_c library at run-time. This is typically caused by one of the following
reasons:

- The file declared to be the snopt7_c library, i.e. $HOME/software/lib/libsnopt7_c.so, is not a shared library containing the necessary C interface symbols (is the file path really pointing to
a valid shared library?)
 - The library is found and it does contain the C interface symbols, but it needs linking to some additional libraries that are not found
at run-time.

We report the exact text of the original exception thrown:

function: evolve_version
where: /home/conda/feedstock_root/build_artifacts/pygmo_plugins_nonfree_1549017917386/work/include/pagmo_plugins_nonfree/snopt7.hpp, 718
what: The snopt7_c library path was constructed to be: $HOME/software/lib/libsnopt7_c.so and it does not appear to be a file

Both libsnopt7_c.so and libsnopt7.so are located in the folder specified and I ran the command patchelf --add-needed libsnopt7.so libsnopt7_c.so as mentioned in Issue #3. Please also find the results of the command ldd libsnopt7_c.so below:

Could you please help me identify the problem? I would really appreciate it.

``` $HOME/software/lib/libsnopt7_c.so and it does not appear to be a file````

I think you are just passing the path wrongly? whats the full path of the library? How do you construct the snopt7 uda?

sanjeev-narayanaswamy commented 5 years ago

Perfect! I replaced $HOME with the full path and it works now. Thanks!

Good to see that you managed to compile snopt and use it in plugins!!!!

Will close the ticket now.
