Checking For X11 Header Files For Beagle
I am using Beaglebone Black Rev C with BB-View CapeManager as follow:
1/ Latest kernel version 'Linux arm 4.15.0-bone2.1 #1 Tue Jan 30 11:48:09 GMT 2018 armv7l armv7l armv7l GNU/Linux'
2/ BBB fire up correctly and screen work correctly
I have recently upgraded to new computer and CentOS 6.4 I was using CentOS 5.1 and compiling C programs that required X11R6 header files and Can't find X11 headers in CentOS 6.4 Share your knowledge at the LQ Wiki. May 24, 2013 I have recently upgraded to new computer and CentOS 6.4 I was using CentOS 5.1 and compiling C programs that required X11R6 header files and Can't find X11 headers in CentOS 6.4 Share your knowledge at the LQ Wiki. X Window System design documentation, manual pages, library reference works, static versions of the shared libraries, and C header files are supplied by the packages depended on by this metapackage. Note that this is a convenience package for users and is not a package for Debian developers to have their package depend on.
3/ Build Qt-everywhere package 5.11 fro io.qtdownload site
4/ The Qt for ARM build successfully and deployed across Beaglbone black
5/ A small test program developed on x86_64bit development Machine, targeted for an ARM.
6/ I am using cross-compiler toolchain 'arm-linux-gnueabihf-gcc-7.2.1-*'
Checking For X11 Header Files For Beagle Rescue
7/ Binary program definitely generating executable for an ARM cpu
8/ After deployment of the binary test program on BBB machine.An error!
9/ './test: /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.25' not found (required by /usr/local/qt5.11/lib/libQt5Core.so.5)'
0/ I ran on BBB 'sudo ldconfig -v
a/ The lib 'ib/arm-linux-gnueabihf/libc.so.6' exists in the given path
b/ After executing command objdump -p test following result I get
c/ On Beaglebonblack I am using rootfs UBUNTU 16.04
List Of C++ Header Files
d/ I only have a barebone Kernel + rootfs on BB Black board.
Your help, advise tip(s) or any info on this problem will be greatly appreciated. Thank you,
To open a connection to the X server that controls a display, useXOpenDisplay().Syntax
Arguments
| display_name | Specifies the hardware display name, which determines the displayand communications domain to be used.On a POSIX-conformant system, if the display_name is NULL, it defaults to the value of the DISPLAY environment variable. |
Description
The encoding and interpretation of the display name isimplementation dependent.Strings in the Host Portable Character Encoding are supported;support for other characters is implementation dependent.On POSIX-conformant systems,the display name or DISPLAY environment variable can be a string in the format:| hostname | Specifies the name of the host machine on which the display is physicallyattached.You follow the hostname with either a single colon (:) or a double colon (::). |
| number | Specifies the number of the display server on that host machine.You may optionally follow this display number with a period (.).A single CPU can have more than one display.Multiple displays are usually numbered starting with zero. |
| screen_number | Specifies the screen to be used on that server.Multiple screens can be controlled by a single X server.The screen_number sets an internal variable that can be accessed byusing the DefaultScreen()macro or the XDefaultScreen()function if you are using languages other than C (see 'Display Macros'). |
Header Files In C
For example, the following would specify screen 1 of display 0 on the machine named ``dual-headed':
dual-headed:0.1
TheXOpenDisplay()function returns a Display structure that serves as theconnection to the X server and that contains all the informationabout that X server.XOpenDisplay()connects your application to the X server through TCP or DECnet communications protocols,or through some local inter-process communication protocol.If the hostname is a host machine name and a single colon (:)separates the hostname and display number,XOpenDisplay()connects using TCP streams.If the hostname is not specified,Xlib uses whatever it believes is the fastest transport.If the hostname is a host machine name and a double colon (::)separates the hostname and display number,XOpenDisplay()connects using DECnet.A single X server can support any or all of these transport mechanismssimultaneously.A particular Xlib implementation can support many more of these transportmechanisms.
If successful, XOpenDisplay() returns a pointer to a Display structure,which is defined in X11/Xlib.h.If XOpenDisplay() does not succeed, it returns NULL.After a successful call toXOpenDisplay() all of the screens in the display can be used by the client.The screen number specified in the display_name argument is returned by the DefaultScreen()macro (or theXDefaultScreen()function).You can access elements of theDisplayandScreenstructures only by using the information macros or functions.For information about using macros and functions to obtain information from theDisplay structure,see Display Macros.
X servers may implement various types of access control mechanisms(see 'Controlling Host Access').
