Subject: [PATCH] Enable 64bit off_t
|
|
|
|
Ensure that off_t is always 64-bit by specifying -D_LARGEFILE_SOURCE
|
|
-D_FILE_OFFSET_BITS=64 this will ensure that normal lseek() function is
|
|
same as lseek64
|
|
|
|
This helps compiling on latest musl where lseek64 and friends are not
|
|
available
|
|
|
|
Upstream-Status: Submitted [https://github.com/Gregwar/fatcat/pull/34]
