Operating Systems Linux Red Hat [Solved] Using ULL suffix in C++ code compiled on RHEL6.4 Post 302890069 by ankit_ka on Tuesday 25th of February 2014 04:03:20 AM

[Solved] Using ULL suffix in C++ code compiled on RHEL6.4

Hi,

I am trying to compile a piece of c++ code using the g++ compiler on an RHEL6.4 system. Here is a code snippet:

Code:
#define CDMA_TIME_OFFSET     315964800000ULL
unsigned long long int ABC=CDMA_TIME_OFFSET;

For some reason, the value assigned to ABC is only the LSB 32-bit of CDMA_TIME_OFFSET. The MSB 32-bit is being ignored.

Below are the relevant compiler options that I am using:

Code:
./x86_64-redhat-linux-gnu-g++ -c -g -pthread -lpthread -m32 -O3 -fno-strict-aliasing -ffast-math -fno-trapping-math -std=c99

Note that I have already tried including the -std=c99 option but that did not help. Could the -m32 that I have used be the reason for MSB 32-bit being ignored?

Thanks !

NAME
g-ir-compiler - typelib compiler. SYNOPSIS
g-ir-compiler [OPTION...] GIRFILE DESCRIPTION
g-ir-compiler converts one or more GIR files into one or more typelib. It can either emit the raw typelib blob (default behavior) or C code (--code). The output will be written to standard output unless the --output is specified. OPTIONS
---help Show help options ---code Emit C code which is suitable for including in a shared library instead of a raw typelib. ---output=FILENAME Save the resulting output in FILENAME. ---verbose Show verbose messages ---debug Show debug messages ---no-init Do not include an initialization snippet to register the typelib in the respository. This can only be used if --code is also speci- fied. ---includedir=DIRECTORY Adds a directory which will be used to find includes inside the GIR format. ---module=MODULE FIXME ---shared-library=FILENAME Specifies the shared library where the symbols in the typelib can be found. The name of the library should not contain the leading lib prefix nor the ending shared library suffix. BUGS Report bugs at http://bugzilla.gnome.org/ in the glib product and introspection component.
