Subject: [PATCH] cmake: Enable 64bit off_t on 32bit glibc systems
|
||
|
|
|
||
|
|
Pass -D_FILE_OFFSET_BITS=64 to compiler flags on 32bit glibc based
|
||
|
|
systems. This will make sure that 64bit versions of LFS functions are
|
||
|
|
used e.g. seek will behave same as lseek64. Also revert [1] partially
|
||
|
|
because this added a cmake test to detect lseek64 but then forgot to
|
||
|
|
pass the needed macro to actual compile, this test was incomplete too
|
||
|
|
since libc implementations like musl has 64bit off_t by default on 32bit
|
||
|
|
systems and does not bundle[2] -D_LARGEFILE64_SOURCE under -D_GNU_SOURCE
|
||
|
|
like glibc, which means the compile now fails on musl because the cmake
|
||
|
|
check passes but we do not have _LARGEFILE64_SOURCE defined. Using the
|
||
|
|
*64 function was transitional anyways so use -D_FILE_OFFSET_BITS=64
|
||
|
|
instead
