I'd like to ask for help/clarification (and maybe even volunteer to
write the required code) to resolve this extension-loading problem.
I have almost a dozen C++ shared libs that implement guile modules,
and regularly struggle to get them loaded correctly. First, they
need to be installed into one of 8 different places:
/usr/lib/guile/2.0/extensions
/usr/local/lib/guile/2.0/extensions
/usr/lib64/guile/2.0/extensions
/usr/local/lib64/guile/2.0/extensions
/usr/lib/guile/2.2/extensions
/usr/local/lib/guile/2.2/extensions
/usr/lib64/guile/2.2/extensions
/usr/local/lib64/guile/2.2/extensions
which is unworkable in practice. So what I usually do is to install
wher I want to, and then do this:
(setenv "LTDL_LIBRARY_PATH"
(if (getenv "LTDL_LIBRARY_PATH")
(string-append (getenv "LTDL_LIBRARY_PATH") ":" path)
path))
(load-extension "libblah" "blah_guile_init")
so that libblah gets found via the env variable. But this too, is not
always ... stable. What I'd like to have is something like
(add-to-extension-path "/path/to/whereever")
that gets searched, when loading guile extensions...
Comments? Suggestions?
