[MPlayer-users] any success compiling with gcc-6 yet?

[Arthur Marsh]

Hi, I've tried building mplayer with gcc-6 but it failed with a compiler
error (which I can post if anyone's interested).

Has anyone else been attempting to build mplayer with gcc-6?

Arthur.

Another weird side-effect of running ./configure with --cc=gcc-6 is that
dirac support gets removed.

I'll wait until Debian releases another snapshot unless anyone can
suggest how to narrow down the bug into a reportable state.

Hi Arthur,

thanks for testing build with gcc-6.

libavcodec/pngdec.c is in FFmpeg, but as I said
before it very much looks like a bug in gcc.

Maybe you should try reporting problems with gcc snapshots
from Debian to Debian first? In the hope they could handle
your report efficiently and maybe forward to gcc upstream
or e.g. send you to us if they think it is not a gcc problem.

OK, I received the reply:

this bug report is useless without the full stacktrace, the command line
options used, and the preprocessed source.

How would I provide that for pngdec.c from an mplayer build?

(e.g. options to ./configure, manual editing of makefile...?)

I added -v -save-temps to the start of the cc flags in config.mak and
the source built fine, and I've sent the output from the build of
pngdec.c and the pngdec.i file to the Debian bug tracker.

Funny how when one added the -v -save-temps that the source built fine.

it was written in the previous mail: internal compiler error.
