I am a newbie and have started using different compilers and tools to make myself familiar with their workings. I wanted to know that how compliant is gcc with the C++ standards. It is pretty obvious that no compiler is close to being completely compliant, but if there are some things which are not according to the ANSI/ISO standard; what are they in gcc?
I will be very grateful if someone who is an expert user of gcc can answer this doubt of mine?
Regards.
gcc can be told comply with standards, lots of them. Pick your favorite:
gcc also has lots of language extensions, but you don't need to use them.
I have been asked to put together some coding standards for the project I am assigned to. I have found documented standards for C/C++, Java but was wondering if there is a good place for UNIX scripting (Korn/Bourne) standards?
Does anyone know of a good place to find information on scripting... (3 Replies)
I'm new to UNIX programming. I'm used to starting my program's versions at 1.0, but I look at all the UNIX programs out there and see things like 0.000.1 or 3.3.000 and I'm wondering what these things really mean. Do people just type anything they feel in there? Are things in pre-release... (6 Replies)

Hi all...
This is just a fun project to see if it is possible to get a square root of a positive integer from 1 to 9200000 to 6 decimal places on a 64 bit architecture machine.
It is coded around dash and the results show the values from 0 to 10000.
Complex numbers can easily be catered for by... (3 Replies)

LEARN ABOUT DEBIAN
builder-cc
BUILDER-CC(1) Debian GNU/Linux BUILDER-CC(1)NAME
builder-cc - gcc wrapper to facilitate pentium-optimizations
SYNOPSIS
export DEBIAN_BUILDARCH=architecture
export DEBIAN_BUILDGCCVER=gcc-version
gcc ...
DESCRIPTION
The builder-cc wrapper is normally used by calling gcc as usual. If the environment variable DEBIAN_BUILDARCH is not set, builder-cc does
nothing, and the real gcc is invoked with the specified arguments.
When the DEBIAN_BUILDARCH environment variable is set, builder-cc invokes gcc with the specified arguments, plus -mcpu=DEBIAN_BUILDARCH
-march=DEBIAN_BUILDARCH This has the effect of telling gcc to use architecture-specific optimizations without changing the command line.
This is particularly useful for package builds.
If DEBIAN_BUILDGCCVER is not set, builder-cc calls gcc.real. If DEBIAN_BUILDGCCVER is set, builder-cc calls gcc-DEBIAN_BUILDGCCVER
instead.
ENVIRONMENT
DEBIAN_BUILDARCH
If set, the architecture to compile for. Useful values are pentium or pentiumpro.
DEBIAN_BUILDGCCVER
If set, the version of gcc to be invoked. Useful values are 3.0 or 2.95.
NOTES
The real gcc is renamed gcc.real, and a diversion is registered with dpkg-divert(1). Thus builder-cc's idea of the default gcc is dictated
by whatever package installed /usr/bin/gcc.
