Hi Antonin,

Thank you for the bug report.  For the short-term, I'll apply the patch
since it's so simple.  Longer-term, I'll coordinate with Tom (the
maintainer) on getting 1.0 into trixie.

Cheers,
tony

Bug#1051704: capnproto: Large File Support not enabled on 32 bits systems

[Antonin Décimo]

Package: capnproto
Version: 0.9.2
Severity: important

Dear Maintainer,

capnproto doesn't define the _FILE_OFFSET_BITS=64 [1] feature test macro for
Large File Support on 32 bits systems. As a reminder, this macro switches
types such as off_t (size of a file) and ino_t (inode number) from 32 to 64
bits. If capnproto encounters a file where these values exceed 32 bits, it'll
 exit with an error.

# kj/filesystem-disk-unix.c++:305: failed: ::fstat(fd, ):
Value too large for defined data type

The issue has been fixed upstream since v1.0.0, in commit 7c8802f [2].
I suggest capnproto be updated to the latest version, or the macro
_FILE_OFFSET_BITS=64 be defined globally at compile-time for this package, or
apply the commit as a patch.
