The following problems are not solved by using libtool's dlopen support:
-
Dlopen functions are generally only available on shared library
platforms. If you want your package to be portable to static platforms,
you have to use either libltdl (see section Using libltdl) or develop your
own alternatives to dlopening dynamic code.
Most reasonable solutions involve writing wrapper functions for the
dlopen family, which do package-specific tricks when dlopening
is unsupported or not available on a given platform.
-
There are major differences in implementations of the
dlopen
family of functions. Some platforms do not even use the same function
names (notably HP-UX, with its shl_load family).
-
The application developer must write a custom search function in order
to discover the correct module filename to supply to
dlopen.
