Greetings!

Officially know as “segmentation fault”, means that the program accessed a memory location that was not assigned. That’s usually a bug in the program. So if you’re writing your own program, that’s the most likely cause. However, this FAQ will concentrate on the possibilities besides that.

It means “Illegal Operation Error” in windows terms. Most likely there is nothing wrong with your installation, your compiler or kernel. It very likely has something to do with your hardware. There are a variety of subsystems that can be wrong, and there are a variety of ways to fix it.

Configuring and Compiling on UNIX

Compiling Tcl on UNIX has two steps: configure and make. In the simplest case you type the following commands to your shell:

cd tcl8.4.16/unix
configure options
make
make test
make install

Configure

The configure script tests your system for different compilation and linking options and generates a Makefile. The configure script is created by GNU autoconf. There are two commonly-specified configure options:

–prefix=directory
This flag specifies the installation directory. The default is /usr/local.
–exec-prefix=directory
This flag specifies the installation directory for architecture-specific (i.e., binary) files. The default is to install architecture-specific files into the location specified by –prefix. This is typically set to a subdirectory of the main prefix, (e.g., /usr/local/solaris-sparc) for sites that want to maintain binaries for multiple architectures. If you just have a single system type, then you can ignore this option.

Note: be sure to use only absolute path names (those starting with “/”) in the –prefix and –exec-prefix options.

To install into the directories /home/user/tcl/bin and /home/user/tcl/lib, for example, you should configure with:

configure –prefix=/home/user/tcl

Tcl’s configure supports the following special switches in addition to the standard ones:

–enable-gcc
If this switch is set, Tcl will configure itself to use gcc if it is available on your system. Note: it is not safe to modify the Makefile to use gcc after configure is run; if you do this, then information related to dynamic linking will be incorrect.
–enable-threads
If this switch is set, Tcl will compile itself with multithreading support.
–disable-load
If this switch is specified then Tcl will configure itself not to allow dynamic loading, even if your system appears to support it. Normally you can leave this switch out and Tcl will build itself for dynamic loading if your system supports it.
–enable-shared
If this switch is specified, Tcl will compile itself as a shared library if it can figure out how to do that on this platform. This is now the default.

Configuring for multiple architectures

Suppose you are building for two platforms, Linux and Solaris, and your installation will be shared by both kinds of hosts. You’ll want to use the –exec-prefix configure option to specify different binary installation directories.

There are two ways you can build for multiple platforms. The first way is to build both platforms in the unix subdirectory. First configure and build for one platform. After you install, type make distclean and then configure and build for the second platorm. Be sure that both the configure and build steps are run on the platform for which you are building. For example, don’t configure under Solaris and then build under HP-UX.

You can also build the different platforms in different subdirectories of the unix directory. If you do this, then you must name the configure script with a full pathname. For example:

cd /home/user/src/tcl8.4.16/unix
mkdir solaris
cd solaris
/home/user/src/tcl8.4.16/unix/configure \
–enable-gcc –enable-shared \
–prefix=/usr/local \
–exec-prefix=/usr/local/solaris-sparc

Configuring Tk

When you configure Tk you may need to tell it where Tcl was built with the –with-tcl flag. This is true, for example, if you build Tcl in a subdirectory of unix as just described. To configure Tk:

cd /home/user/src/tk8.4.16/unix
mkdir solaris
cd solaris
/home/user/src/tk8.4.16/unix/configure \
–enable-gcc –enable-shared \
–with-tcl=/home/user/src/tcl8.4.16/unix/solaris \
–prefix=/usr/local \
–exec-prefix=/usr/local/solaris-sparc

Building with Make

What is Make?

After you configure your Makefile, type “make”. This will create a library archive called libtcl.a or libtcl.so and an interpreter application called tclsh that allows you to type Tcl commands interactively or execute script files. When you build Tk, you create libtk.a or libtk.so and the wish executable.

Type “make test” to run an exhaustive test suite. In most cases there should not be test failures. The Tk test suite, however, does have some tests that depend on font metrics and the window manger, which can vary across platforms. The README file in the tests subdirectory has documentation about the test suite.

Type “make install” to install Tcl binaries and script files in the directories you specified with –prefix or –exec-prefix during the configure step. You’ll need write permission on the installation directories to do this.

If you have trouble compiling Tcl, check out the platforms list. This is an on-line database of porting information. We make no guarantees that this information is accurate, complete, or up-to-date, but you may find it useful. If you get Tcl running on a new configuration, we would be happy to receive new information to add to the database. We’re also interested in hearing how to change the configuration setup so that Tcl compiles out of the box on more platforms.

Greetings!!

If you have Fedora Core 5/6 or CentOS 5 or Red Hat Enterprise Linux 5 on your server and are experiencing troubles with respect to upgrades (forced or otherwise) of Click Be! or Fantastico or Universina, please check the wget version that you have on your server.

If it is wget-1.10.2-3.3.fc5 or wget-1.10.2-7.el5 or wget-1.10.2-8.fc6.1, we suggest that you replace it immediately with an older and/or stabler version. This version does not honor the “-P” switch.

An alternate version that we suggest is wget-1.10.2-3.2.1

You can use the following commands for this purpose:

Code:

rpm -qa wget ;
wget http://fedora.osmirror.nl/core/development/i386/Fedora/RPMS/wget-1.10.2-3.2.1.i386.rpm ;
rpm -e wget ;
rpm -ivh --force wget-1.10.2-3.2.1.i386.rpm ;
rpm -qa wget ;

Note: You must execute the commands shown above as root.

You will also want to put wget on /etc/yum.conf’s exclude= line so the OS doesn’t automatically reinstall the buggy version.

Reports suggest that the version of wget included with Fedora Core 7 does not have this problem, so that may be a better option for some people.

Regards,

Harry

mod_layout is an Apache module that provides a Footer and/or Header directive to automatically include output from other URIs at the beginning and ending of a Web page. It can be used to wrap documents for a standard look and feel for a site (or to insert banners on any given document in a site). mod_layout is currently known to support mod_perl, PHP and Apache JServ and should support just about any other type of handler.

You can use static html or a cgi/perl/php script to insert.

If you are running mod_layout on a cPanel server and want to insert (execute) a script be prepared to have lots of fun…

1) cd /usr/local/src; wget http://www.tangent.org/download/mod_layout-3.2.1.tar.gz
2) tar xvfz mod_layout-3.2.1.tar.gz
3) cd mod_layout*
vim Makefile -w

replace “apxs” “/usr/local/apache/bin/apxs” — Makefile

Or where even you have your apxs file for apache. Give the path for it.

Replace

DEF = -Wall -DDEBUG

with

DEF = -Wall

4) Save the file Makefile

5) Make it and install it.

make
make install

Thats it. You Check the installed modules on phpinfo();

Cheers!

Download it from here : http://tomcat.apache.org/download-55.cgi Download it from here http://archive.apache.org/dist/tomcat/tomcat-5/archive/v5.0.25/bin/

tar -zxvf jakarta-tomcat-5.x.xx.tar.gz

move  jakarta-tomcat-5.x.xx /opt

cd /opt

ln -s jakarta-tomcat-5.0.25 tomcat

In order for Tomcat to startup and shutdown, you will also need to add an environment variable pointing to the Tomcat directory (CATALINA_HOME), and one variable pointing to your Java SDK directory (JAVA_HOME). I will make the following assumptions:

JAVA_HOME

Java is installed into /opt/IBMJava2-141.

CATALINA_HOME

Tomcat is installed into /opt/jakarta-tomcat-5.x.xx and symlinked to /opt/tomcat.

Insert the following lines inside /etc/profile or /root/.bashrc.

export JAVA_HOME=/opt/IBMJava2-141 export CATALINA_HOME=/opt/tomcat

# echo $CATALINA_HOME
# echo $JAVA_HOME

If you get a blank line, or if the directory points anywhere besides where it is supposed to, you will have to correct these environment variables first, before continuing.

If everything is fine, you can start Tomcat with the following command. As root,

# $CATALINA_HOME/bin/startup.sh

To check if Tomcat is running fine, you should open a browser and point the URL to http://localhost:8080. You should see the default Tomcat welcome page. It would be a good idea, at this point, to browse the documentation or try out the example servlets and JavaServer Pages samples.

To stop Tomcat, as root,

# $CATALINA_HOME/bin/shutdown.sh

If Tomcat does not start and you downloaded the zip file, the cause is probably due to permissions. Ensure that the following files are executable : inside $CATALINA_HOME/bin directory,

# chmod +x startup.sh
# chmod +x shutdown.sh
# chmod +x tomcat.sh 

After you have made the files executable, try starting and stopping Tomcat again.

3.5. Running Tomcat as Non-Root User

I don’t believe there any issues with running Tomcat as root user. However, for the more security-conscious readers out there, here are some instructions on running Tomcat as a non-root user.

At this stage, the Tomcat packages, files and binaries are owned by root. We will first need to create a Tomcat user and group that will own these files, and under which Tomcat will run.

Tomcat User :: tomcat

Tomcat Group :: tomcat

Not too imaginative, huh ? We will now create the Tomcat user and group. Open a terminal window and, as root,

# groupadd tomcat
# useradd -g tomcat -d /opt/tomcat tomcat
# passwd tomcat

Notice that we specified the home directory of Tomcat to be /opt/tomcat. Some people believe that this is good practice because it eliminates an additional home directory that needs to be administered.

Now, we will put everything in /opt/tomcat under Tomcat user and group. As root,

# chown -R tomcat:tomcat /opt/tomcat

If /opt/tomcat is a symlink to your Tomcat install directory, you’ll need to do this:

# chown -R tomcat:tomcat /opt/jakarta-tomcat-5.x.xx

Verify that JAVA_HOME and CATALINA_HOME environment variables are setup for tomcat user, and you should be good to go. Once the Tomcat binaries are under Tomcat user, the way you invoke it will be different.

To start Tomcat,

# su - tomcat -c /opt/tomcat/bin/startup.sh

To stop Tomcat,

# su - tomcat -c /opt/tomcat/bin/shutdown.sh

Cheers!!

 Greetings,

check which library file ismissing by using

ldd /path/to/that/script.

You can have it fixed by installing some rpms for the current linux version you are running with it. You need to install

compat-libstdc++*****.rpm
