Yes, that should work, but...

... under guix, $HOME/.guix-profile/{lib,...} is the standard prefix ;-)

 

So would it be possible to modify the test so that it takes LIBRARY_PATH into account? (If it were C, the AC macros would do that automatically.) Or could one simply use AC_CHECK_LIB?

 

If not, a possible work-around would be to check explicitly with the $HOME/.guix-profile/lib prefix.
