Thanks!
It is a too long code to attach it here. I may need to go back to check the code again. The machine is:
On another machine with smaller RAM, I only got warning but not error on it, and it went through to have all the programs compiled.
Is there any option(s) that I may have missed from the compiling part? Thanks again.
Hi, I'm converting a C program that I made using the Visual Studio. I now use GCC (over Linux) and can't find some equivalences. I changed my __int64 definitions to unsigned long long, but can't find an equivalent to the microsoft i64toa() function, which let you convert a char* to a 64 bit... (1 Reply)

Hi,
I wrote a simple code in C++ converting from UpperToLower case characters. However, my compiler gives me a warning:
"warning: conversion to 'char' from 'int' may alter its value".
Any tips?

Hello everyone.
I'm stuck with an error message that neither I nor any of my computer science peeps can understand. The program I wrote is meant to be a simple decimal to binary converter, but with this message it's more complicated than I thought.

Dear all,
I am using C and ROOT for programming. And I need to incorporate following in my code.
char *fps=NULL;
int dec=0,sign=0;
float mean = h1->GetMean(1); //0.001298
fps= fcvt(mean,6 , &dec, &sign);
I need to provide this mean as const char to some other function to get... (8 Replies)
I'm writing a DB to manage books & dvd's for the library.
So after they added more books/dvd's, they press the print button and all newly added entries are printed.
That is, as it prints all 'printed = false' entries, which (false) is the default value for that field for each new entry.

hardened-cc
HARDENED-CC(1) Debian GNU/Linux HARDENED-CC(1)NAME
hardened-cc - gcc wrapper to enforce hardening toolchain improvements
SYNOPSIS
export DEB_BUILD_HARDENING=1
gcc ...
DESCRIPTION
The hardened-cc wrapper is normally used by calling gcc as usual when DEB_BUILD_HARDENING is set to 1. It will configure the necessary
toolchain hardening features. By default, all features are enabled. If a given feature does not work correctly and needs to be disabled,
the corresponding environment variables mentioned below can be set to 0.
ENVIRONMENT
DEB_BUILD_HARDENING=1
Enable hardening features.
DEB_BUILD_HARDENING_DEBUG=1
Print the full resulting gcc command line to STDERR before calling gcc.
DEB_BUILD_HARDENING_STACKPROTECTOR=0
Disable stack overflow protection. See README.Debian for details.
DEB_BUILD_HARDENING_RELRO=0
Disable read-only linker sections. See README.Debian for details.
DEB_BUILD_HARDENING_FORTIFY=0
Don't fortify several standard functions. See README.Debian for details.
DEB_BUILD_HARDENING_PIE=0
Don't build position independent executables. See README.Debian for details.
DEB_BUILD_HARDENING_FORMAT=0
Disable unsafe format string usage errors. See README.Debian for details.
NOTES
System-wide settings can be added to /etc/hardening-wrapper.conf, one per line.
The real gcc symlinks are renamed gcc.real, and a diversion is registered with dpkg-divert(1). Thus hardened-cc's idea of the default gcc
is dictated by whatever package installed /usr/bin/gcc.
