Cygwin compilation problem

[Diego Biurrun]

Hi everybody!

libdvdcss 1.2.9 does currently not compile under Cygwin (latest Cygwin,
Windows XP SP2), here is the error message:

gcc -shared .libs/libdvdcss.o .libs/device.o .libs/css.o .libs/ioctl.o
.libs/error.o -o .libs/cygdvdcss-2.dll -Wl,--enable-auto-image-base
-Wl,--out-implib,.
libs/libdvdcss.dll.a
Creating library file: .libs/libdvdcss.dll.a
.libs/device.o: In function `libc_seek':
/home/diego/src/libdvdcss-1.2.9/src/device.c:440: undefined reference to
`__lseeki64'
collect2: ld returned 1 exit status
make[3]: *** [libdvdcss.la] Error 1

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/diego/src/libdvdcss-1.2.9'
make: *** [all] Error 2

1.2.8 does not compile as well, but gives a different error. Sorry, I
cannot test subversion right now.

Correction: 1.2.8 compiles if I run ./bootstrap befor ./configure.

Subversion does not compile either. Here is the fix from MPlayer CVS.
Please apply or commit a different fix that I can port to MPlayer then.

Rejected? Applied? No interest?

Do you see problems or a way to fix this differently?

I have no Cygwin system to test it. But from what I see, this patch
simply uses lseek instead of the non (no longer?) existent _lseeki64.
What is expected together with such a patch is an explanation on whether
lseek understands 64 bit offsets in Cygwin.

Cygwin wrapper provides 64-bit lseek and defines off_t as a 64-bit type.
MinGW uses MSVCRT lseek, which is 32-bit. MSVCRT also exports the
obscure _lseeki64, which is the MS 64-bit version. This function is not
available in Cygwin.
