Shared object "libdl.so.2" not found, required by "libnvidia-encode.so.1" : where to find the correct version of libdl.so.2 ?

Hello.

When I try to run obs I get this error message :

Code: 
error: os_dlopen(libnvidia-encode.so.1->libnvidia-encode.so.1): 
Shared object "libdl.so.2" not found, required by "libnvidia-encode.so.1"

Is there a method to know where should be stored and which version should be the library that libdl.so.2 hyperlink should point to as asked by "libnvidia-encode.so.1" ?

libdl.so.2 is a pointer that should point to a library like one of these :

Code: 
libdl-2.17.so
libdl-2.31.so
libdl-2.32.so

For example if it points to : libdl-2.31.so I get the following error :

Code: 
error: os_dlopen(libnvidia-encode.so.1->libnvidia-encode.so.1): /usr/local/lib/libc.so.6: 
version GLIBC_ABI_DT_RELR required by /usr/local/lib/libdl.so.2 not found

If it points to : libdl-2.17.so I get the following error :

Code: 
error: os_dlopen(libnvidia-encode.so.1->libnvidia-encode.so.1): /usr/local/lib/libdl.so.2: 
unsupported file layout

If it points to : libdl-2.32.so I get the following error :

Code: 
error: os_dlopen(libnvidia-encode.so.1->libnvidia-encode.so.1): /usr/local/lib/libc.so.6: 
version GLIBC_ABI_DT_RELR required by /usr/local/lib/libm.so.6 not found

Creating an hyperlink called "libm.so.6" which points to library libm-2.32.so :

Code: 
ln -s libm-2.32.so libm.so.6

I get the following error :

Code: 
error: os_dlopen(libnvidia-encode.so.1->libnvidia-encode.so.1): /usr/local/lib/libc.so.6: 
No space available for static Thread Local Storage

unfortunately none of those works. So now I'm very curios to understand what it really wants.
 
1. there's no libdl in FreeBSD, dlopen(3) and friends are part of FreeBSD's libc.
2. FreeBSD's libc is at ABI version 7 (libc.so.7) and certainly doesn't have any GLIBC_* symbol versions.
3. The Linuxulator's glibc (libc.so.6) certainly isn't installed in /usr/local/lib.

So, all in all, WTF is this all about?
 
Its obs (installed from the packages) which wants to load the Linux libraries to take advantage of the nvidia driver and of the CUDA libraries :

Until now I wasn't aware such a hack exists.

Once upon a time there was a port named www/linuxpluginwrapper, which is still referenced in the examples section of libmap.conf(5). So, the idea is not all new, just the implementation is.

There are, of course, quite a few limitations. For example, I wanted to use the shim for Widevine, but the recent versions of libwidevinecdm.so were found to directly invoke Linux syscalls bypassing libc, so now there is a yet another wrapper specifically for it.
