This package contains several programs for beginners.
It includes as sources and binaries.
Programs available here are:
fileOperations
A program demonstrating how to operate with files.
Performs reading and writing operations.
simpleThread
Demonstrates thread operations.
When run several times the output may be different, depending how the
threads are executed.
server
This is server-side program which demonstrates how a server works.
The user has to specify on which port the server will listen.
After reading a message the server exits.
Example: ./server 50000
client
This program is used as a client for the server, and should use the same
port.
The client sends a message to the server and reports whether the server
got the message or not.
Example: ./client <hostname or localhost> 50000
=== How to add a new C file to the project ===
This is a guide to adding a new C file using autotools, by editing the
files in the project directory.
Let's say that we have added a file named my_test.c to the project
directory and we want to build a binary my_test from that file.
Let's also say that my_test.c includes the <pcre.h> header and uses the
function pcre_compile.
The steps for compilation and making binaries below assume your current
working directory is the project directory. When running from a different
directory append -p <path_to_your_project> to the commands.
1) Update the file Makefile.am to add the new binary name at the end of
bin_PROGRAMS like:
bin_PROGRAMS = <existing_binaries> my_test
2) Tell autotools to build the my_test.c file, by adding a new line to
Makefile.am:
my_test_SOURCES = my_test.c
3) To add a test to the configure script to check whether the header is
on the target system call devassistant with these parameters:
da modify c header --header pcre.h
4) To add a test for the library call devassistant with these parameters:
da modify c lib -l libpcre -f pcre_compile>
The project makefile will be updated so the binary will be linked
with the library.
5) When the project is buildable and no errors occurs then you can add
your binary to the RPM, by modifying the <project_name>.spec file
stored in your project directory.
In that file add your binary in the %install section as a new line like:
install -p -m 755 -D my_test ${RPM_BUILD_ROOT}%{_bindir}/my_test
You also need to add that file in %files section with a new line like:
%{_bindir}/my_test
Update the %changelog section to record the change.
6) To build the RPM package leave your project directory and run the
command:
da create c c -n <your_project_name> -b
