Re: [Gnash-dev] Gnash for ARM, "undefined reference to `lt_libltdlc_LTX_preloaded_symbols'"

[David Goldsmith]

I actually fixed it by just removing the "extern" from the
corresponding line in ltdl.c.
Then I encountered a problem with Boost, but downgrading to a slightly
older version seems to have cleared that up.
Now to build with plugin enabled, and badda bing badda boom, YOUTUBE!
Or so goes the theory.
