Anonymous CVS access

Anonymous CVS access is now available to SILC CVS repository. The repository includes everything related to SILC project; source codes, documentation and even these web pages. The CVS access is of course public but it is intended for developers. After you have checked out the SILC source tree you should read README.CVS file from the source tree or rest of this web page.

Also note that this is the closest to real time development you can get thus you cannot expect that the source tree would work or even compile. While it is our intention that the trunk would always at least compile there might be situations when it will not.


Browsing the Source Tree

If you want to browse the source tree using web browser before checking out the tree with CVS use following link:

Web Access to CVS repository

Note that this is not real-time access to the CVS repository. It is updated once a day. If you want real-time access then checkout the CVS repository.


Howto Checkout The Source Tree

The repository can be checked out by using anonymous pserver with CVS.

For those who are using sh/ksh/bash the check out is done as follows:

export CVSROOT=:pserver:cvs@cvs.silcnet.org:/cvs/silc

cvs login
cvs co silc


For those who are using csh/tcsh the check out is done as follows:

setenv CVSROOT :pserver:cvs@cvs.silcnet.org:/cvs/silc

cvs login
cvs co silc


If you don't want to set $CVSROOT environment variable you can set the path to the cvs as command line options:

cvs -d:pserver:cvs@cvs.silcnet.org:/cvs/silc login
cvs -d:pserver:cvs@cvs.silcnet.org:/cvs/silc co silc

What ever method you decide to use, after you have done cvs login you will be prompted for password:

CVS password: silc

Type the password "silc" and press Enter.

The actual SILC source tree is checked out using the cvs co silc command, described above. This command will fetch the source tree and save it into directory named silc. SILC CVS repository currently does not have any branches thus this will check out the trunk. The size of the trunk is currently about 13 MB but will grow in the future.


What SILC Source Tree Includes

SILC Source tree includes a lot more stuff that appears in public distribution. The source tree includes, for example, internal scripts, configuration files, SILC webpages etc. These never appear on a public distribution.

Following directories currently exist in SILC source tree.

doc/

Includes all the SILC documentation. Some of the documentation are generated when distribution is generated. The automatically generated files must never be commited to CVS.

includes/

Includes SILC include files.

lib/

Includes SILC libraries. There maybe libraries on the CVS that does not appear on public distribution.

public_html/

Includes the official SILC web pages and everything that relates to them. This directory never appears on public distribution.

silc/

Includes SILC client. There can be some extra files that will never appear in public distribution, such as, configuration files.

silcd/

Includes SILC server. There can be some extra files that will never appear in public distribution, such as, configuration files.


Howto Compile SILC Source Tree

After checkout from CVS the SILC source tree must be prepared for configuration and compilation. To compile the source tree, give,

./prepare
./configure --enable-debug
make

The ./prepare script is included in to the source tree and it never appears in public distribution. The script prepares the source tree by creating configuration scripts and Makefiles. The prepare must be run every time you make some changes to configuration scripts (however, making changes to Makefile.am's does not require running ./prepare).

As a developer you should read the ./configure script's help by giving ./configure --help and study all of its different options. Also, you should configure the script with --enable-debug option as it compiles SILC with -g (debugging) option and it enables the SILC_LOG_DEBUG* scripts. Warning is due here: The debugging produced by both cilent and server is very heavy, thus it is common to test the programs as follows:

./silc -d -f configfile 2>log
./silcd -d -f configfile 2>log


Howto Clean SILC Source Tree

To entirely clear the source tree to the state after it was checked out from CVS, give,

./prepare-clean

This calls `make distclean' plus removes automatically generated files by hand. It also removes *.log files. However, it will not remove any other files you might have created.


Makefiles and configuration files

Developers should never directly write a Makefile. All Makefiles are always automatically generated by ./prepare and later by ./configure scripts. Instead, developers must write Makefile.am files. There are plenty of examples what they should look like. If you change Makefile.am during development you don't have to run ./prepare, just run normal make.

Configuration files are the files that ./prepare automatically generates and what will be included into public distribution. ./prepare creates for example the ./configure script that is not commited to the CVS. `configure.in' is the file that developers must edit to change ./configure script. After changing one must run ./prepare.
