For 64-bit offset, use int fseeko(FILE *stream, off_t offset, int whence); for definition of off_t, use #include <sys/types.h> You can read more in Mac OS X man pages.

I have a C application I am trying to compile under Mac OS X 10.6.4, which includes large file support. The application builds correctly under Linux.

Here is the Darwin kernel I am using:

------------------------- $ uname -v Darwin Kernel Version 10.4.0: Fri Apr 23 18:28:53 PDT 2010; root:xnu-1504.7.4~1/RELEASE_I386 -------------------------

My gcc installation is as follows:

------------------------- $ gcc --version i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664) -------------------------

My Makefile is as follows:

------------------------- CC=gcc CFLAGS=-D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE -O3 -Wformat -Wall -pedantic -std=gnu99

all: myApp rm -rf *~

myApp: myApp.o ${CC} ${CFLAGS} myApp.o -lbz2 -o myApp rm -rf *~

clean: rm -rf *.o myApp -------------------------

The issue is that my application makes calls to "fseeko64" and "fopen64", and it uses the "off64_t" type for offsets. When I attempt to build, I get the following related warnings and errors:

------------------------- $ make myApp gcc -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE -O3 -Wformat -Wall -pedantic -std=gnu99 -c -o myApp.o myApp.c myApp.c: In function ‘extractData’: myApp.c:119: warning: implicit declaration of function ‘fseeko64’ myApp.c:119: error: ‘off64_t’ undeclared (first use in this function) myApp.c:119: error: (Each undeclared identifier is reported only once myApp.c:119: error: for each function it appears in.) myApp.c: In function ‘extractMetadata’: myApp.c:305: warning: implicit declaration of function ‘fopen64’ myApp.c:305: warning: assignment makes pointer from integer without a cast -------------------------

My code builds without errors under Linux. What changes can I make to the source code to add large file support when building under Darwin?

Thanks for your advice.
