I actually do have manpages-dev installed, so I can get a man page on
fgetc, but it still doesn't give me a man page for stuff in float.h.
Now that I see that man works for the functions and macros and not for
the header name (But why wouldn't man-k pick that up?), I do a man
pow and notice there is a powl() function that looks like it might
work but maybe doesn't:
---
#include stdio.h
#include stdlib.h
#include float.h
#include math.h
int main( int argc, char * argv[] )
{
double temp;
long double ltemp;
printf( max double digits: %d, double exponent %d\n, DBL_DIG,
DBL_MAX_10_EXP );
printf( max double value: %Lf\n, (long double) DBL_MAX );
temp = pow( 2, 2000 );
ltemp = powl( 2, 2000 );
printf( 2^2000 as double: %f\n, temp );
printf( 2^2000 as long double: %Lf\n, ltemp );
ltemp = ltemp + 1.0;
printf( 2^2000 + 1 as long double: %Lf\n, ltemp );
return EXIT_SUCCESS;
}
---
which prints out the value of 2^2000 okay, but fails to increment it.
Which makes sense, since we have no reason to believe long double ever
gets 2000 bits of significance, but powers of two should be accurately
stored up to the limit of the exponent.
Thus the need for GMP or MPFR or similar libraries. (Or you can just
do it in python. ;)
http://en.wikipedia.org/wiki/GNU_Multi-Precision_Library
and
http://en.wikipedia.org/wiki/MPFR
I note:
cat /usr/lib/gcc/x86_64-linux-gnu/4.7/include/float.h
a constant, DEC_EVAL_METHOD,
#undef DEC_EVAL_METHOD
#define DEC_EVAL_METHOD2
might force all operations and constants to the range and precision
of the _Decimal128 type, which might be of interest for compiling
environments which do not make long doubles longer than doubles -- a
kind of last chance on those systems. Unless he only needs the
constant, and doesn't need precision/accuracy, the OP is going to want
GMP or MPFR or the like, if python can't do his job.
Since I seem to be convincing myself against my better judgment that I
have time, and since I've always wanted to play with the
multiprecision stuff, I'm going to install libgmp-dev and read the
website
http://gmplib.org/
and risk stealing the OP's opportunity for learning.

Reg: gcc option for printing large number (large double)
Hi,
I have an issue in printing a large number in a c program. Please find
below the code snippet :
#include math.h
int main()
{
double temp = 0.0;
temp = pow(2, 2000);
printf(The value of temp is %lf\n, temp);
return 0;
}
I compiled and ran as below:
[balamurugan@balamurugan C_Programs]$ gcc test.c -o test
[balamurugan@balamurugan C_Programs]$ ./test
The value of temp is _inf_
But for the same expression, I am able to get the value from python,

temp is a double. In your ordinary environment, doubles are stored in
64 bits. But that's 64 bits total, and you have to have some room for
the exponent. In some environments, you have 128 bits for doubles, but
that's not the usual case.
Checking the foat.h header should give you some idea how large a
number you can store in a double. Except I don't see any sign of
float.h in /usr/include. Hmm.
Checking my copy of the old C89 standard, doubles are only guaranteed
to have more than 10 digits accuracy with a maximum storeable value of
at least 10 to the 37th power.
temp = pow(2, 2000);
2 to the 2000 power is, at any rate, at least 2000 bits long. That's
way more than 128 bits even.
Counting the digits of output from Python, that's way more than 37
decimal digits.
printf(The value of temp is %lf\n, temp);
return 0;
}
I compiled and ran as below:
[balamurugan@balamurugan C_Programs]$ gcc test.c -o test
[balamurugan@balamurugan C_Programs]$ ./test
The value of temp is inf
inf, borrowed to invoke the idea of infinity, indicates that the
number is too large to store.

Not so much an option as a library, that is not part of the standard.
Several libraries, in fact. I don't remember their names right
off-hand, don't seem to have them loaded in my system, either. Looking
up BigInt led me to them in the past.

gcc unable to find 32-bit gtk-x11-2.0 library (x86_64)
Hi all, I am currently investigating a build failure of GNU Classpath/Jikes RVM on Debian Squeeze 6.0.4 (cf. http://jira.codehaus.org/browse/RVM-942): The problem is that gcc is unable to find the 32-bit gtk-x11-2.0 library, even though it sits right there in /usr/lib32: ls /usr/lib32/libgdk-x11-2.0* /usr/lib32/libgdk-x11-2.0.so.0 /usr/lib32/libgdk-x11-2.0.so.0.2000.1 The offending gcc command used by during the Jikes RVM build boils down to this: gcc -m32 -L/usr/lib32 -lgdk-x11-2.0 /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../libgdk-x11-2.0.so when searching for -lgdk-x11-2.0 /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../libgdk-x11-2.0.a when searching for -lgdk-x11-2.0 /usr/bin/ld: skipping incompatible /usr/lib/libgdk-x11-2.0.so when searching for -lgdk-x11-2.0 /usr/bin/ld: skipping incompatible /usr/lib/libgdk-x11-2.0.a when searching for -lgdk-x11-2.0 /usr/bin/ld: cannot find -lgdk-x11-2.0 (The -m32 is needed as Jikes RVM itself is really a 32-bit VM.)

gcc using Pipes Done!
lee writes:
And leftchannel_pipe is supposed to be an array? Without seeing more of
your program, we're left in the dark ...
Now that I got it working, here it is. All this does is
to give you an 8-bit 8000 sample per second audio feed from both
the left and right channels of the sound card as
/tmp/leftchannel and /tmp/rightchannel. For it to work, you must
cat both files in to either a program that continuously reads
them or cat both in to respective files because the fifo I ended
up using instead of pipes blocks if you stuff bytes in to the
input and there is nothing to read the fifo yet.
If you start this code without anything connected to
both fifos, it patiently blocks until both streams are going,
then it works fine.
There is a catch as to the type of audio you can use
with this code because it actually has to configure the sound
card to sample in stereo at 32000 samples per second. The
Nyquist low-pass filter needed on both the input and output of
the sound card is set to block sounds above 16000 HZ but the
sound streams we want can only carry audio at 4000 HZ. I do not
have any kind of Nyquist filtering built in to this code so the
best audio to feed it is audio from radio scanners,
communications receivers and any other device with a limited
audio bandwidth so that the low-pass filtering is already there.
Do anything else such as feeding music from a FM broadcast radio
or television sound source in to the splitter gives you sound
that is peculiar to listen to because frequencies above 4 KHZ
heterodyne with the sampling rate and produce what are called
aliases. Trust me. S sounds sound like tearing paper and chimes
or bells put one in mind of the world through a bad ear ache.
Here is the splitter code. I used sample code from
others to learn how to setup the sound card. Many thanks to all.

gcc using Pipes Some Progress
Ivan Jager writes:
Rather than using fwrite() you could just use write(), which takes a

other stdio functions rather than the *nix syscalls, you could
use fdopen() to get a FILE* corresponding to the pipe's fd.
If you check the pipe manpage, you'll find an example of how to
use pipes.
What I ended up doing was to use write as you suggested.
I had confused the file descriptor with the file so write was
what I really needed. In the write command, I forgot the
address of operator so once I fixed that I had:
if( write(leftchannel_pipe[1], leftbyte, 1) 0)
{
printf(write error!\n);
exit (1);
}
That appears to work but I need the pipe to show up as a
newly-created file so that a separate program can attach to it
and that's where it looks like I need fdopen. In the case of
this particular program, the pipe function gave me 7 and 8 as
the descriptors for leftchannel_pipe[0] and leftchannel_pipe[1]
so I added the following line to the code:
if ((leftchannel_pipe[0] = fdopen(leftdata,r)) == NULL) {
perror(leftdata);
exit(1);
}
Leftdata is a string set to leftchannel and should have been
the file name that shows up when the code runs.
I may be misunderstanding how this all works, but it
should have opened the file discriptor already created by the
pipe() function.
At that point, I get the bad file descriptor error.
One interesting point. the man page for pipe on my
debian lenny system exists in section 7 and discusses pipes and
fifo's but there is no example. I did, however, find an man page
by doing a Google search which did include an example of a
program that uses fork to let data flow from whatever wrote it
to whatever needs to read it.
I think I am on the wrong track, here, because I want to
run this code and see 2 new entries pop up in the file system
which are each data streams, one to the left channel of my sound
card and the other, to the right channel.
mkfifo is probably what I need.
Except for the I/O, this project is almost done. For the
curious, I wrote some code years ago that uses /dev/dsp which,
when read or written without any fcntl commands, either produces
or plays 8-bit audio samples at 8,000 samples per second. It's
horrible for music, but fine for communications-level audio such
as from short wave radios, scanner receivers and amateur radio
gear.
You only get the input from the left channel, however.
If you also want the right channel, you have to set the sound
card to stereo at 32,000 16-bit samples per second so to get the
8-KHZ samples, you must throw away 3 out of 4 samples and then
mask off the 8 LSB's from each channel to get the same thing as
before plus change from signed to unsined data. I actually got
that to work so what's left is to build the I/O or the O, to be
specific so that this code is sort of a railroad switch to route
all the left-channel data and right-channel data to their
respective outlets.
Finally, I wrote a VOX or Voice Activated Relay program
that takes one stream and only writes to a file when there is
sound. When I get the splitter to work, I will be able to put a
VOX on each channel and double the number of streams to record
from.

gcc using Pipes
I want to send two output streams from a code module I wrote to
two pipes so that other programs can read the streams.
The rest of the module works but I am doing something
wrong when writing to a pipe.
The way I understand pipes, you write to one end. A
small buffer fills and the operation blocks until something else
reads the read end of the pipe to clear the buffer.
The bytes are defined as unsigned char and I can send them to
test files with fwrite with no problem but here is what happens
when I try to send to a pipe. Here is the trace with annotation:
Breakpoint 2, main () at 2pipes.c:47

#Let's see what the uninitialized integers are.

#After the step, we should have two file descriptors.
(gdb) output leftchannel_pipe
{7, 8}
#good! I also did the same thing to open a second pipe called
#rightchannel_pipe.
(gdb) output rightchannel_pipe
{9, 10}
#that also looks right, but let's try to write to leftchannel_pipe.
main () at 2pipes.c:98

(gdb) step
Program received signal SIGSEGV, Segmentation fault.
0xb76a78d1 in fwrite () from /lib/i686/cmov/libc.so.6
That looks like what you get when confusing the contents
of a pointer with the name of that pointer but the fwrite
statement is what I used when writing to a normal file and that
worked.

It also happens when you try to use 7 as a pointer.
Note that fwrite does not take a file descriptor but a FILE*. I'm
not sure what options you're passing gcc, but I would have
expected it to at least warn you that you were passing an int as
a pointer.
Rather than using fwrite() you could just use write(), which takes a
file descriptor. Alternately, if you really want to use fwrite or
other stdio functions rather than the *nix syscalls, you could
use fdopen() to get a FILE* corresponding to the pipe's fd.
If you check the pipe manpage, you'll find an example of how to
use pipes.
Also, I'm not sure what kind of modules you're writing, but if
they both live in the same address space, then using pipes is
like calling your cellphone from your work phone so that you can
talk to yourself. If your modules are separate processes, then
that's exactly what pipes are for.

Problema con GCC al compilar
Hola Listeros, Nuevamente recurro a ustedes por que he tenido algunos problemas con un equipo y que les paso a comentar, sucede que instale GCC en mi caso la version es gcc version 4.3.2 (Debian 4.3.2-1.1). Bueno el problema es que intenten compilar un servicio (Unreal). y no puedo por que arroja el siguiente mensaje de error. checking for gcc... gcc checking for C compiler default output file name... configure: error: C compiler cannot create executables Viendo esto encuentro que aparentemente no esta reconociendo el GCC o por lo menos la version instalada y debido a ello es que no es capas de compilar. La cosa es que volvi a tras la versión de GCC remove con el apt dicha version e instale una más antigua para probar. Ahora aquí tengo otro problema y es el que me esta dando mayor dolor de cabeza. Cuando Instale GCC (version vieja). 4.2 paso que como tampoco no funciono para compilar, volvi a la 4.3.2-1.1 y además instale el build-essential y el apt posterior a esto quedo mal, ahora no puedo remover ni instalar nada por que en caso de instalar me dice que haga un apt-get -f install para concluir un proceso entiendo y cuando quiero remover algo no deja por que dice que: libc6: Depends: libc-bin (= 2.11.2-6+squeeze1) but it is not going to be installed Recommends: libc6-i686 but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). En definitiva deje la cagada y recurro a su ayuda, de ante mano gracias.

The problem I ran into was that Matlab R2010b works with gcc 4.3 but not 4.4 and I didn't know how to configure Matlab to use 4.3. However, I now see that that can be solved by editing ~/.matlab/R2010b/mexopts.sh, changing CC=gcc to CC=gcc-4.3 So I didn't need the use the debian alternatives after all. But see my other response for how I did it.

Many Debian packages work on ubuntu unchanged. And many others don't. Worst of all, some packages may be unchanged but don't work due to changes in _other_ packages that Ubuntu deploys. This mostly affects packages in universe which are imported from Debian and built automatically, but might never have been tested by anyone in Ubuntu.

This is where the BSD version of make has an advantage over GNU make.
It checks for system-wide defaults in the file /etc/make.conf:

AS I think using an alias 'gcc -lm' is not a good idea. It may be looking
AS easier for this particular C file, but '-lm' would be linked always for
AS even in the case of hello_world.c which is really unnecessary.
The additional linking won't do much besides take an extra millisecond
of time and add around 25 bytes to your binary; that's what I saw when
comparing on a Deadrat Enterprise system. Build the executable both
ways, run nm and chop the first 10 characters to see for yourself.
The results should be identical.
You're right about the alias -- it works fine right up to the part where
someone changes their login shell or alias setup. It's safer to use a
script as a front-end, so you can check for environment variables in a
global or user-specific config file:
#!/bin/sh
# front-end for make with preset preferences.
export PATH=/usr/local/bin:/bin:/sbin:/usr/sbin:/usr/bin
cbase='make.conf'
for cfg in /etc/$cbase $HOME/etc/$cbase; do
test -f $cfg . $cfg
done
exec /usr/bin/make ${1+$@} # Use full path just to be safe...
exit 1
Under Linux, the config file looks like this:
me% cat $HOME/etc/make.conf
# Default values for make.
export CC=gcc
export CFLAGS=-O2 -pipe -funroll-loops
export COPTFLAGS=-O -pipe
Comparison:
me% cat Makefile

how to configure gcc

The best way to avoid that is to write a makefile to use that.

That method is really for cases when there is a long list of options, or they are complicated and easy to get wrong. Just put everything in a makefile, and call make. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Thanks for answer yes but normally gcc should be configured, where is the config file, for example sshd_config is a config file for ssh, vsftpd.conf for ftp server and so on .., so where is the config file for gcc, just this I couldn't find it. thanks a lot regards -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

It's in the same place as the config file for ls, cp, and rm. (There isn't one.) sshd runs continuously as a daemon, as does vsftp, which is part of why they have configuration files.

It may be looking easier for this particular C file, but '-lm' would be linked always for even in the case of hello_world.c which is really unnecessary. The best way to solve this problem is as I mentioned previously. use makefiles

Hacer downgrade de gcc.
Hola a todos, Estoy intentando instalar vmware server en un Ubuntu. Llegados a un momento en la instalación me dice que no existe el módulo vmware, creo, para la versión de kernel que tengo instalada y que si deseo generarla. Le digo que me lo genere, pero llegados a la compilación me dice que el kernel se compiló con la versión de gcc 4.2.2 y que la que hay actualmente instalada es la 4.2.3 y puede dar problemas, que si deseo continuar o no. Evidentemente, como no podía ser de otra manera, la compilación casca... :-( ¿Cual sería la forma legal de hacer un downgrade del gcc, si es que la hay?.
