Hi,
After reading a recent thread on `guile-user', it occurred to me that
`lt_dlopenext ()' doesn't allow to pass information about the version of
a module that is requested.
This is quite unfortunate, especially for Guile, since Guile modules
load C libraries using `dynamic-link' which is roughly the Scheme
version of `lt_dlopenext ()'. This precludes having several versions of
a given extension installed at once since each of these versions need to
load a particular version of its companion C library.
So, I think it would be very nice to have something like:
/* Open a module with the file name FILENAME which is compatible with
revision REVISION of interface INTERFACE. The module should have
been linked with `-version-info'. */
lt_dlhandle lt_dlopen_version (const char *filename,
unsigned interface,
unsigned revision);
And similarly for `lt_dlopenext ()'. And I believe this may also be
useful for other kinds of programs, like programs that use plug-ins (for
instance, plug-ins could be compiled with a `-version-info' that
reflects the version of the plug-in API exposed by the program).
What do you think?
Thanks,
Ludovic.
