[GRASS-dev] WinGrass7 - disable LFS

GRASS GRASS developer
1

Has disabling LFS to be set explicitly for configure in the windows-world?
  
I've tried --disable-largefile,

but again there is

[...]
checking if system supports Large Files at all... yes
[...]
Large File support (LFS): yes
[...]

in the build-log.

what have to be done to disable LFS for building WinGrass7?

configure.in is broken; it sets USE_LARGEFILES according to whether
LFS is detected, regardless of whether it is enabled. MinGW has LFS,
but it's not in a form which currently works with GRASS.

I'm builiding Grass7 on WinVista32. so there shouldn't be LFS?

Configure will detect it, but it doesn't work. GRASS assumes that
defining _FILE_OFFSET_BITS=64 will make off_t a 64-bit type. Windows
has a 64-bit offset type (actually, it has two of them) and functions
which work with it, but you have to use them explicitly; there's no
macro to "redirect" off_t, lseek(), etc to 64-bit versions.
