[Freeswitch-dev] fedora 12 compiler error and workaround

[Douglas Hubler]

Here is the complier error (sorry for pasting it in here, but you'll
see why it's important in a second...)

Creating mod_amr.so...

For some reason "-shared" is not on the link line

Don't ask me how i figured this out, but If I change in file build/modmake.rules
   SOLINK = -shared -Xlinker -x
to
   SOLINK = --shared -Xlinker -x

Everything compiles and freeswitch runs.  Something in the gnu tool
chain wants to strip out any "-foo" parameter to gcc but adding an
extra "-" it allows it through.

So i didn't find the problem, but i did find a weird workaround.
