On Unix systems it is not possible to dynamically load a
library shared by a static executable, I don't know if it
works differently for Windows.
This is because it is absolutely necessary to link libdl
dynamically, you cannot link static.
For GNU/Linux systems there is this alternative to
dlopen/dlsym that does not require dynamic link:
https://www.gnu.org/software/libtool/manual/html_node/Dlpreopening.html
This is a topic I almost have no knowledge, therefore a
question.
If I understand this StackOverflow question correctly, it is
possible to call dynamically a shared object from a static
library (with dlopen):
https://stackoverflow.com/questions/17862272/dlopen-a-dynamic-library-from-a-static-library-linux-c
But I understand from you it is not possible dynamically call a
shared object from a static executable.
Therefore it works for static libraries but not for statically
executables?
Kind regards

Static libraries are simple collections of object files, there is
no difference between linking a static library or several object
files
If you notice when going to compile the executable linka libdl
and the static library, then the executable will be linked to
dynamic library and will not be a static executable.
