[Buildroot] BR 2012.rc1 :: XORG compilation issue

[MERCADIER Johann]

Hi everybody,

   back with a new problem. I try to add a graphical output to my
pandaboard.
   It seems gcc try to compile 'liblua.so' as a static lib the raison why
it suggest to add the -fPIC option. What I don't understand using a
all-in-one tool like BR it is where I do that? Do I have to modify manually
the Makefile? then if it works how I do report that to the community?
  If someone could help me?

Bye

[Buildroot] [PATCH] lua: fix non-shared library build

[Arnout Vandecappelle]

Building without BR2_PACKAGE_LUA_SHARED_LIBRARY failed because of
missing -ldl.  dl is used by lua's dynamic module loading.

On ARM, there's still a warning:
ld: warning: creating a DT_TEXTREL in object.

I haven't checked if lua actually works on the target.  But it certainly
won't be worse than before :-)
