I am trying to make the transition from C++ to D. I've hit a

Error 42: Symbol Undefined __lseeki64.
Here is a simple example of code that gives the error upon
compilation.
import std.stdio;
import etc.c.zlib;
void main(string[] args)
{
char[] fName = "C:\\Users\\Matthew
Gamble\\Documents\\sample.bam\0".dup;
char[] mode ="r\0".dup;
gzFile bamFile; //no error here
bamFile = gzopen(&fName[0],&mode[0]); //this is where the

I'm using DMD32 D Compiler v2.067.1 on a windows 8 64 bit
machine. Working from either Visual D in Visual Studio 2013
Community and Coedit as IDEs gives the error. I'm probably
doing something obviously wrong, so have mercy. If etc.c.zlib
is not the preferred way to read from a binary gzipped file any
advice would be appreciated. Thanks.
Hi.
The etc.c.zlib headers are, I think, just translations of the C
headers and allow you to link with an external library. If the
library is not installed, or the compiler/linker cannot find them
then you may have a link error. Are you sure that Visual Studio
knows where to find the zlib library binary ? Can you try
compiling your project with DMD from the command line appending
-L-lz (that might work on linux, but I don't know on windows)?
There is a program called everything from void tools that may be
helpful in finding the library file if its location is not
obvious.
