[Tinyos-help] BUG: tinyos-2 libtoscomm.so needs -fPIC flag (w/patch)

[Mr. Jonathan A. Gomez]

I looked at the documentation of gcc at
  
  http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc
  
and found the options described in section 3.18.
  
>From what I can tell, the difference between the two options -fpic and 
-fPIC has to do with whether it checks for system-dependent restrictions 
on the size of the global offset table that would be generated, avoiding 
creating PIC code in that case.

If says for the -fpic flag: "If the GOT size for the linked executable 
exceeds a machine-specific maximum size, you get an error message from 
the linker indicating that -fpic does not work; in that case, recompile 
with -fPIC instead. (These maximums are 8k on the SPARC and 32k on the 
m68k and RS/6000. The 386 has no such limit.)".

I don't know much about cygwin, but it sounds like the usage of these
two different flags is a bit more of an issue than just cygwin vs.
linux.  It sounds like it is somewhat architecture-specific too.
"This option makes a difference on the m68k, PowerPC, and SPARC".

The full text for the options, of course, is available at the link
above by going to the appropriate section.

I tried to look up -fpic/PIC on cygwin, but I wasn't having much
success.  I'd love to know where to get references.
     

Sincerely,

    Jon.
