[Paraview] dlopen question

[Mattijs Janssens]

In our code we use dlopen with RTLD_LAZY|RTLD_GLOBAL to optionally load 
additional libraries.

We noticed that this gives problems in the paraview reader. The same code 
which happily loads when running from the command line now gives undefined 
symbols when used through the reader.

E.g. the additional library libAdditional uses a symbol aaa from library 
libmain which is already a dependency of my application. (so 'ldd 
application' shows up libmain). My application does a dlopen of libAdditional 
and it all works fine.

Now when invoked in a reader (the reader itself I assume is loaded using 
dlopen into Paraview?) the dlopen of libAdditional complains about unresolved 
symbol aaa. Funnily enough it works if we first do a dlopen of libmain and 
then of libAdditional.

Is this related to the flags passed into dlopen? To complicate the matter, 
from what we heard, the problem does not appear on OSX.

Regards,

Mattijs
