Public bug reported:
...and because luarocks hardcodes an x86_64 workaround for lua.org
upstream's non-pic brain damage ("it works on i386!"), the luarocks
workaround is undone by luarocks.deb lying to it about the architecture.
The exact bug is present in Debian, except inverted: the architecture is
hardcoded to x86_64. I forget, is that "grave"? Should I file there too?
$ luarocks build lpack
[...]
gcc -O2 -I/usr/include/lua5.1 -c lpack.c -o lpack.o
gcc -shared -o pack.so -L/usr/local/lib lpack.o
/usr/bin/ld: lpack.o: relocation R_X86_64_32S against `.rodata' can not be used
when making a shared object; recompile with -fPIC
lpack.o: could not read symbols: Bad value
$ grep fPIC /usr/share/lua/5.1/luarocks/cfg.lua
if proc == "x86_64" and not defaults.variables.CFLAGS:match("-fPIC") then
defaults.variables.CFLAGS = defaults.variables.CFLAGS.." -fPIC
$ grep UNAME_M /usr/share/lua/5.1/luarocks/config.lua
LUAROCKS_UNAME_M=[[i686]]
$ uname -m
x86_64
$ grep -A 10 proper /usr/share/lua/5.1/luarocks/cfg.lua
-- A proper installation of LuaRocks will hardcode the system
-- and proc values with config.LUAROCKS_UNAME_S and config.LUAROCKS_UNAME_M,
-- so that this detection does not run every time. When it is
-- performed, we use the Unix way to identify the system,
-- even on Windows (assuming UnxUtils or Cygwin).
system = config.LUAROCKS_UNAME_S or io.popen("uname -s"):read("*l")
proc = config.LUAROCKS_UNAME_M or io.popen("uname -m"):read("*l")
if proc:match("i[%d]86") then
proc = "x86"
elseif proc:match("amd64") or proc:match("x86_64") then
proc = "x86_64"
$ # So if we simply remove the i686 line from config.lua, luarocks will
get the architecture right. Feel free to set it in /etc in postinst
instead....
$ # apply attached patch directly to /usr/share/lib/lua5.1 because I'm
grumpy
$ luarocks build lpack

Do not use 'module' as a build type. Use 'builtin' instead.
