#1128 closed defect (fixed)

build failure on debian squeeze (double typedef)

With current ffmpeg git, the gcc of stable debian (4.4.5) is irritated by the touble occurence of typedef SwrContex?:

In file included from libswresample/audioconvert.h:32,

from libswresample/audioconvert.c:32:

libswresample/swresample_internal.h:78: error: redefinition of typedef ‘SwrContext?
libswresample/swresample.h:47: note: previous declaration of ‘SwrContext?’ was here

I fixed it that way:

I am sure you come up with whatever way you prefer to avoid doubling that typedef;-)

Please add the first line of "git log".
(Compilation works fine here with an old version of gcc since yesterday night.)

I see now that that exact change has been pushed with commit ac6798dbc118a8d63a6e57f8a0120666a2449efa. Well, there is a certain window between pulling the tree and the build advancing up to the breakage with old gear.

The issue can be closed,
