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
error hits
}
Is that a compiler error or a linker 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.
char[] fName = "C:\\Users\\Matthew
Gamble\\Documents\\sample.bam\0".dup;
bamFile = gzopen(&fName[0],&mode[0]);
would be probably be more easily understood if written as:
string fName = "C:\\Users\\Matthew
Gamble\\Documents\\sample.bam";
bamFile = gzopen(fName.ptr,mode.ptr);
as string _literals_ are nul terminated in D ( but not
dynamically constructed ones: use .toStringz on them) assuming
that gzopen doesn't manipulate it's arguments (I would very much
doubt that).
Also if you're trying to do bam parsing/manipulating/whatever try
to get a hold of Artem Tarasov who occasionally posts on these
forums. He wrote the worlds fastest bam parser in D. He might be
able to give you some hints on further questions.
