I tried:
defaults.external_deps_dirs = { "/usr/local", "/usr",
"/lib/i386-linux-gnu", "/usr/lib/i386-linux-gnu",
}
but that seemed to get messed up with the
external_deps_subdirs = {
bin = "bin",
lib = "lib",
include = "include"
},
so it seems luarocks needs the last four characters to be /lib So I:
mkdir /usr/symlinks
ln -s /usr/lib/i386-linux-gnu /usr/symlinks/lib
And in /usr/local/share/lua/5.2/luarocks/cfg.lua:
defaults.external_deps_dirs = { "/usr/local", "/usr",
"/usr/symlinks",
}
Which gave me my next error message:
Error: Could not find expected file gdbm.h, or gdbm.h for GDBM --
you may have to install GDBM in your system and/or pass GDBM_DIR
or GDBM_INCDIR to the luarocks command.
so it seems luarocks needs lib/ and include/ to be subdirs of the
same directory. So I:
ln -s /usr/include /usr/symlinks/include
and now it works !! :-) And should continue to work, for all other
modules on this machine :-) Bit rough and primitive, though.
The logic behind looking at /etc/ld.so.conf (and thence /etc/ld.so.conf.d/*)
is that that's what ld does (see step 8):
3. On an ELF system, for native linkers, ... search the
contents of the environment variable "LD_RUN_PATH".
4. On SunOS, ... search any directories specified using -L options.
5. For a native linker, the search the contents of the environment
variable "LD_LIBRARY_PATH".
6. For a native ELF linker, the dirs in "DT_RUNPATH" or "DT_RPATH"
of a shared library are searched for shared libraries needed by it.
The "DT_RPATH" entries are ignored if "DT_RUNPATH" entries exist.
7. The default directories, normally /lib and /usr/lib.
8. For a native linker on an ELF system, if the file
/etc/ld.so.conf exists, the list of directories found in that file.
A suitable rockspec featuring ~> should follow some time today...
