[root@localhost Sockets-2.3]# cat INSTALL
C++ Sockets Library :: installation instructions


Unix (and Cygwin/Mingw on windows)
==================================

1.  Change the 'PLATFORM =' line in Makefile

    Possible values are
       linux-x86-32
       win32-cygwin
       solaris9-sparc-64
       macosx
       solaris8

2.  If you want to use ssl encrypted socket communication, the library
    has support for the third-party library openssl. If necessary, add
    the following include directory to Makefile:

    INCLUDE = -I<path to openssl>/include

    The openssl include directory contains only one directory named
    'openssl', in which all header files can be found.

    OpenSSL support is enabled by default.

    If you don't need encrypted communications, make sure to comment
    out this line in the file 'sockets-config.h':

    #define HAVE_OPENSSL

3.  If you really need thread-safe dns lookups, and your operating has
    support for *addrinfo and *nameinfo function calls, make sure this
    line in 'sockets-config.h' is commented:

    #define NO_GETADDRINFO

    By default, dns lookups using getaddrinfo/getnameinfo is disabled.

4.  If your operating system supports SCTP, there might be a slight
    chance the sctp code in the library works. Uncomment this line in
    'sockets-config.h' to try:

    //#define USE_SCTP

5.  If you need IPv6 support, uncomment this line in
    'sockets-config.h':

    //#define ENABLE_IPV6

6.  Type 'make'

7.  If all builds ok, you'll find the static library file 'libSockets.a'
    in the build directory.


When compiling the application, any flags used when compiling the library
also needs to be present when including the library .h files. All flags
can be retrieved using the 'Sockets-config' executable. Add something like
this in your Makefile:

CFLAGS += `Sockets-config`
CPPFLAGS += `Sockets-config`

When linking an application using the library, make sure the object and
library files are in correct order on your link command line:

    First:    Application object files
    2nd:       -lSockets
    3rd:      openssl libraries
    Finally:  Everything else, ending with -lpthread


windows
=======

Project files for various IDE's can be found here:

    Project/           Visual studio 6.0
    Project.net/       Visual studio .NET
    DevCpp/            Dev C++

Please see steps 2-5 above for some details on configuring the library.

When linking on cygwin/mingw, add the following libraries:
 -lwsock32
 -lws2_32

[root@localhost Sockets-2.3]#

기본설정은 openssl을 사용하도록 구성되어 있다. 여기서는 단지 prefix 옵션이 /usr/local로 되어 있다.

[root@localhost Sockets-2.3]# cat Makefile

# platforms:
#  linux-x86-32
#  win32-cygwin
#  solaris9-sparc-64
#  macosx
#  solaris8
PLATFORM =  linux-x86-32

# .h files installed to $(PREFIX)/include/Sockets
# static lib .a files installed to $(PREFIX)/lib
PREFIX =    /usr/local

[root@localhost Sockets-2.3]# make
...
[root@localhost Sockets-2.3]# make install
cp libSockets.a /usr/local/lib
cp -a *.h /usr/local/include/Sockets
install Sockets-config /usr/local/bin
[root@localhost Sockets-2.3]#

Sockets 라이브러리를 사용하기 위해서는 #include 헤더파일 을 사용한다.

컴파일시 옵션으로 -I/usr/local/include/Sockets 옵션을 붙여주고

라이브러리 경로와 .a 파일을 링크하도록 -L/usr/local/lib -lSockets -lpthread -lssl -lcrypto 을 입력해준다.

즉, 아래의 형식으로 컴파일 한다.

# g++ [컴파일할 소스파일들] -o [생성될 실행파일] -I/usr/local/include/Sockets -L/usr/local/lib -lSockets -lpthread -lssl -lcrypto

# lftpget http://packages.sw.be/rpmforge-release/rpmforge-release-0.3.6-1.$dist.rf.$arch.rpm # rpm -Uhv rpmforge-release-0.3.6-1.$dist.rf.$arch.rpm

위에서 자신의 서버에 맞는 rpm 파일을 설치하고 yum 으로 아래 두개의 라이브러리를 설치한다.

# yum install csockets csockets-devel

.h 헤더파일 file : /usr/include/Sockets
