Hello, I have never had a successful compile on the 2.6 kernel. On every arch in which I try to compile gcc I get either "i686-pc-cygwin-ar command not found or "i686-suse-linux-ar command not found. This always happens during the make process after configure checks for ar and finds it's just ar.... (2 Replies)

Hi Everyone,
I can ask what is the option to compile a 64 bits program using gcc. I have looked everywhere but can't find it. Before I used to use cc and the -q64 flag was the option to generate the 64 bits binary. Can anyone tell me what is the flags when using gcc. Thanks...... (3 Replies)
Heyas
I'm currently trying to make a fresh build from scratch/source of FFMPEG.
This said, it brings quite a tail with it, so the use of a script was very obvious.
Anyway, i'm currently stuck at named package.
Lets ignore the tarball/download line, as the error is after.

First of all -- thanks for being patient with me. I hope I'm submitting this correctly. Also I haven't done UNIX Admin since the early 1990's. I'm actually a DBA. But, since I'm the one in the office with the UNIX experience, I'm the SA.
I haven't been able to compile GCC 6.3.0 which I need... (9 Replies)

XvCreateImage(3) libXv Functions XvCreateImage(3)NAME
XvCreateImage, XvShmCreateImage - create an XvImage
SYNOPSIS
#include <X11/extensions/Xvlib.h>
XvImage * XvCreateImage (Display *dpy, XvPortID port,
int id, char *data,
int width, int height);
XvImage * XvShmCreateImage (Display *dpy, XvPortID port,
int id, char *data,
int width, int height,
XShmSegmentInfo *shminfo);
ARGUMENTS
dpy Specifies the connection to the X server.
port Specifies the port the XvImage will be used with.
id Specifies the format of the image to be created by the XvImageFormatValues id.
data Specifies the image data.
width, height
Specifies the desired width and height of the image.
DESCRIPTION XvCreateImage(3) is similar to XCreateImage(3). XvShmCreateImage(3) is similar to XShmCreateImage(3). The library will allocate the XvIm-
age structure and fill out all fields except for data. Width and height may be enlarged in some YUV formats. The size of the data buffer
that needs to be allocated will be given in the data_size field in the XvImage. Image data is not allocated by this function. The client
may pass a pointer to the preallocated memory as data or may allocate the memory and fill in the XvImage structure's data field after the
data_size field has been filled out by the server. The XvImage structure may be freed by XFree(3). Shared memory segments are
attached/detached with XShmAttach(3)/XShmDetach(3).
RETURN VALUES
XvImage has the following structure:
typedef struct {
int id;
int width, height;
int data_size;
int num_planes;
int *pitches;
int *offsets;
char *data;
XPointer obdata;
} XvImage;
id A descriptor for the format from the XvImageFormatValues structure returned by XvListImageFormats(3).
width, height
The width and height of the image in pixels.
data_size
The size of the data buffer in bytes.
num_planes
The number of image planes.
pitches An array of size num_planes indicating the scanline pitch in bytes. Each plane may have a different pitch.
offsets An array of size num_planes indicating the byte offset from data to the start of each plane.
data A pointer to the start of the data buffer.
obdata A private field for holding SHM info. This field will be set up by the client libraries so the programmer will generally need not
be concerned with this field.
DIAGNOSTICS
[XvBadPort]
Generated if the requested port does not exist.
[XvBadAlloc]
Generated if the X server was unable to allocate resources required to complete the operation.
[BadMatch]
Generated if incompatible arguments were supplied, such as a port that isn't capable of displaying XvImages.
