Hi,
unfortunately it doesn't work without the lib prefix either. I tried
quite a few combinations:
libgneural
libgneural-0.0.0
gneural
gneural-0.0.0
gneural-0
From distant memory I recalled that ldconfig needs to be executed to
avoid LD_LIBRARY_PATH. So I created a conf file for ldconfig at
/etc/ld.so.conf.d/gneuralnetwork.conf (I'm on Parabola):
/opt/gneural/lib
But I'm out of luck. Do you have any other hints?

The string you pass to Lt_dlopen should not contain the "lib" prefix.

Hello,
I librarified gneural_network, patches pending at:
https://lists.gnu.org/archive/html/gneuralnetwork/2016-04/msg00015.html
In that patch library is called libgneural_network, locally I
modified name to libgneural.
Next I installed gneural_network at /opt:
/opt/gneural/

I try to load that library with lt_dlopen:
#include <ltdl.h>
#include <stdio.h>
int
main (int argc, char** argv)
{
lt_dlhandle handle;
lt_dlinit ();
handle = lt_dlopen ("libgneural");
if (handle != NULL)
{
printf ("Loaded library\n");
lt_dlclose (handle);
}
else
{
printf (lt_dlerror ());
printf ("\n");
}
return 0;
}
This program fails with error message: file not found. What am I
doing wrong? The command line is:
$ gcc -l ltdl -o dlopen dlopen.c
$ LD_LIBRARY_PATH=/opt/gneural/lib ./dlopen
