The warnings I can fix, but the linker error ... looks like your libc was compiled without large file support Ok - obviously you have a 64bit architecture... so not sure what the problem there is.

[bitmelt]

It looks like like there's a macro (LSEEK) that should be used instead of lseek64 directly. Created a pull request #28 . Tests pass.

[rico666]

merged. Should compile now
