I have a problem at make step to install a downloaded package consisted of different programs.
1) I have tried
to correct the weird characters, but this seems to be a temporary fix. What is the permanent fix?
2) The error message is
The code fragment of the function prototype is:
I know the function is declared as char *, which is conflict with the returned value as a boolean "false". How to fix this syntax problem?
Thanks a lot!

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)

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.

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
