1. Getting Started
The following instructions take you through a sequence of steps to get the default configuration up and running.
(a) You will need the following prerequisites.
- REQUIRED: This tar file izem-%VERSION%.tar.gz - REQUIRED: A C compiler (gcc is sufficient) Also, you need to know what shell you are using since different shell has different command syntax. Command "echo $SHELL" prints out the current shell used by your terminal program.
(b) Unpack the tar file and go to the top level directory:
tar xzf izem-%VERSION%.tar.gz cd izem-%VERSION% If your tar doesn't accept the z option, use gunzip izem-%VERSION%.tar.gz tar xf izem-%VERSION%.tar cd izem-%VERSION%
(c) Choose an installation directory, say /home/<USERNAME>/izem-install, which is assumed to non-existent or empty.
(d) Specify the installation directory:
for csh and tcsh: ./configure --prefix=/home/<USERNAME>/izem-install |& tee c.txt for bash and sh: ./configure --prefix=/home/<USERNAME>/izem-install 2>&1 | tee c.txt Bourne-like shells, sh and bash, accept "2>&1 |". Csh-like shell, csh and tcsh, accept "|&". If a failure occurs, the configure command will display the error. Most errors are straight-forward to follow.
(e) Build Izem:
for csh and tcsh: make |& tee m.txt for bash and sh: make 2>&1 | tee m.txt This step should succeed if there were no problems with the preceding step. Check file m.txt. If there were problems, do a "make clean" and then run make again with V=1. make V=1 |& tee m.txt (for csh and tcsh) OR make V=1 2>&1 | tee m.txt (for bash and sh) Then go to step (3) below, for reporting the issue to the Izem developers and other users.
(f) Install Izem:
for csh and tcsh: make install |& tee mi.txt for bash and sh: make install 2>&1 | tee mi.txt This step collects all required executables and scripts in the bin subdirectory of the directory specified by the prefix argument to configure.
2. Testing
We package a test suite in the Izem distribution. You can run the test suite in the test directory using:
make check OR make testing
The distribution also includes some Izem examples. You can run them in the examples directory using:
make check OR make testing
If you run into any problems on running the test suite or examples, please follow step (3) below for reporting them to the Izem developers and other users.
3. Reporting Problems

4. Etymology
Izem means Lion in Berber. "I" here is pronounced "E" in English (the whole word will sound similar to "Eden").
