Full Discussion: Problem creating files greater than 2GB
Top Forums UNIX for Advanced & Expert Users Problem creating files greater than 2GB Post 302103288 by hegemaro on Wednesday 17th of January 2007 11:19:37 AM

With the GNU gcc compiler, specifying the "-m64" option generates code for the 64-bit environment which includes 8-bytes for a file offset. I normally use low-level I/O with which you can specify the O_LARGEFILE status flag when working in a 32-bit environment.

In short, try compiling with the -m64 option.
