[This bug is targeted to the upcoming bookworm release]

Please keep this issue open in the bug tracker for the package it
was filed for.  If a fix in another package is required, please
file a bug for the other package (or clone), and add a block in this
package. Please keep the issue open until the package can be built in
a follow-up test rebuild.

The package fails to build in a test rebuild on at least amd64 with
gcc-12/g++-12, but succeeds to build with gcc-11/g++-11. The
severity of this report will be raised before the bookworm release.

The full build log can be found at:
http://qa-logs.debian.net/2022/06/09/gcc12/ffmpegfs_2.10-2_unstable_gcc12.log
The last lines of the build log are at the end of this report.

To build with GCC 11, either set CC=gcc-11 CXX=g++-11 explicitly,
or install the gcc, g++, gfortran, ... packages from experimental.

  apt-get -t=experimental install g++

Common build failures are new warnings resulting in build failures with
-Werror turned on, or new/dropped symbols in Debian symbols files.
For other C/C++ related build failures see the porting guide at
http://gcc.gnu.org/gcc-11/porting_to.html

GCC 11 defaults to the GNU++17 standard.  If your package installs
header files in /usr/include, please don't work around C++17 issues
by choosing a lower C++ standard for the package build, but fix these
issues to build with the C++17 standard.

Thanks for the report. The issue has already been fixed, see
https://github.com/nschlia/ffmpegfs/commit/9a4ba638e38d030b7c5311cf527edafbd88bb537

There was the cstring header missing.

The fix will be available with release 2.11, I'll close this when it was
released.

Source: ffmpegfs
Architecture: source
Version: 2.11-1
Distribution: unstable
Urgency: medium
Maintainer: Norbert Schlia <nschlia@oblivion-software.de>
Changed-By: Norbert Schlia <nschlia@oblivion-software.de>
Closes: 1012925
Changes:
 ffmpegfs (2.11-1) unstable; urgency=medium
 .
   * Feature: Issue #86: Smart transcode now detects if a source file is audio
     only and uses the correct target format. For example, with
     --destination=webm+mp3, if one MP4 input file contains a video stream and
     another an audio stream only, the resulting files will be WebM (for the
     video input) and mp3 for the audio only file.
   * Feature: Issue #137: Add --no_subtitles option to turn subtitles off.
   * Bugfix: Smart encode selected the video format for cue sheet tracks,
     regardless of the input format. This has been fixed now.
   * Bugfix: Fix a crash that occurs when a DVD/Blu-ray is transcoded to audio
     only.
   * Bugfix: If the track performer field in the cuesheet is blank, try album
     performer instead.
   * Bugfix: Failing to mount Fuse during "make check" went unnoticed as the
     result code (which was supposed to be 99) was actually 0. Return the correct
     result code, failing the operation as expected.
   * Bugfix: The Docker build command contained a "make check" which actually
     failed altogether. Step has been removed. "make check" mounts Fuse, but this
     requires privileges that do not exist during "docker build".
   * Bugfix: On error, mremap () returns MAP_FAILED rather than NULL. Fixed a
     check for incorrect error conditions, which could cause the application to
     crash or return illogical error messages.
   * Bugfix: Issue #119: Fix a problem that caused frame set generation to fail
     sometimes. It seems to be related to the nremap() issue.
   * Generally revisited documentation, logging, and display texts. Improved
     grammar, formatting, and fixed quite a few typos that escaped all
     proofreading sessions.
   * The FFmpeg API INFO and DEBUG level log output has been changed to the
     FFmpegfs DEBUG level. What FFmpeg considers "INFO" is far too chatty.
   * Frequent memory reallocations when creating HLS segments have been reduced
     to speed up processing.
   * Optimised logging to save CPU time by not formatting log entries that are
     not written anyway at their log level.
   * Logging has been revised to shorten file paths and remove mount, input, and
     cache paths. Log the additional portion only to reduce log file size and
     improve readability.
   * Bugfix: To fix the build with GCC 12, add the missing include headers
     (closes: #1012925).
