Bug#47777: errors compiling mpeglib from source

[Martin Vogt]

Hello,

can you please try the following:
I never tested it, but if this works, please
make a diff against the old version, I will
then commit it.

Heres the "tutorial":

please change all inline assembly labels from "<label>" to "<label>_%=" to
prevent duplicate symbol errors caused by inlining due to optimization
flags. "%=" generates a unique number per instance and thus inlining
becomes possible.
  
Example:
  
label: movl %eax,(%ebc,%ecx,4)
       decl %ecx
       jnz  label

The above is impossible with inlining as there are multiple instances of
"label" defined. This is fixed below:

label_%=: movl %eax,(%ebc,%ecx,4)
          decl %ecx
          jnz label_%=

Now every inlined instance has a unique label and thus inining is possible.
  

regards,

Martin

The way I usually get around this is to simply skip building mpeglib. I'm using a LinuxFromScratch 3.3 (approx.) system and I've had this problem with KDE 3, 3.0.1, 3.0.2 and 3.0.3.
