I am trying to load at runtime a dynamic library using ITK (let&#39;s call =
it<br>
lib.so), within a program also linked to ITK.<br>
To do this, I am using :<br>
<br>
void* handle =3D dlopen(&quot;lib.so&quot;, RTLD_LOCAL | RTLD_LAZY)<br>
<br>
but it crashes (I receive an H5::DataSpaceIException).<br>
<br>
This works when I remove linking to ITK from the program that use the<br>
library, or when I remove it from the library itself, so I guess I have<br>
conflicting links between both programs, but I can&#39;t figure it out.<br>
<br>
Thank you !<br>
