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?

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)

sb2-init - initialize a target for scratchbox2
SYNOPSIS
sb2-init [OPTION]... [TARGETNAME] [COMPILER[:SPECS]] [SECONDARY_COMPILER...]
DESCRIPTION
sb2-init initializes a target for scratchbox2. If no options or other parameters are given, already initialized targets are listed.
A scratchbox2 target is simply a light-weight, symbolic name for a configuration set. A target does not contain anything that is active,
like running processes; hence a user never "works inside a target". Instead, sessions are used for all active operations. Sessions are
created by the sb2 command.
sb2-init is expected to be run in the directory you want to use as the target root filesystem.
TARGETNAME is the name of the target to initialize. If it refers to an existing target, then the target is re-initialized. Otherwise a new
one is created.
COMPILER is full path to a cross-compiler (gcc), of the form $HOME/arm-2006q3/bin/arm-linux-gcc. An optional SPECS parameter is path to
the compiler specs file.
If more than one compiler is specified, additional compilers are available by version number (e.g. if the primary is known as "gcc" and
"gcc-4.1", the secondary may be "gcc-3.4", etc)
Note that the compiler is usually used during the target creation process to determine CPU architecture of the target system.
OPTIONS -c "command"
specify cpu transparency command, for example: "qemu-arm", "sbrsh" or "qemu-arm -R 256M". CPU transparency method is the program
which is used to execute foreign binaries, that the host computer can not execute directly.
-p "command"
specify cpu transparency command for staticly linked native binaries.
-r [hostname]
generate sbrsh config using remote device address
-l [hostname]
NFS server/localhost address seen by remote device
-d set target as default scratchbox2 target (default target can also be set later with the sb2-config command)
-m [mapping_mode]
use mapping_mode as default. Default for this is "simple"
-h Print help.
-n don't build libtool for the target
-N don't generate localization files for the target
-s skip checks for target root's /usr/include etc.
-t [tools_dir]
set directory containing the build tools distribution
-C "options"
add extra options for the compiler, for example: -C "-fgnu89-inline"
-A arch
manually override target architecture
-M arch
manually override machine name (see uname(2)). This defaults to the target architecture (see option -A)
-v display version
EXAMPLES
mkdir $HOME/buildroot
cd $HOME/buildroot
[fetch a rootfs from somewhere and extract it here]
sb2-init -c qemu-arm TARGET /path/to/cross-compiler/bin/arm-linux-gcc
