Då som cad är det viktiga för mej i dator värden och då inte det finns ett vettigt 3 d alternativ som jag har sett allt annat verkar finnas hur mycket som helst av. Men som jag vet så var många cad program från början skrivna för unix och jag kan då inte förstå att det ska var så omöjligt att få in ett bra cad program i linux. I installations filen som jag kommer att bifoga har sedan så står det att det det ska gå med just ubuntu. Men som förvirrad linux användare så börjar jag att mycket lite överväga fall ubuntu är programet för mej. Än så länge endast lite!
BRL-CAD on Linux README
=======================
Below are installation and platform notes of relevance to particular
Linux distributions.
Table of Contents
-----------------
Ubuntu
PPC64 Linux
Ubuntu
------
Users of Ubuntu and other similar packaging distributions of Linux
will need to ensure that a few essentials are in place before you will
be able to compile BRL-CAD.
Following the build instructions in the INSTALL file, if you are
starting from configure then you will need:
gcc (3+, e.g. 4.0.3)
make (e.g. gnu make 3.8.0)
If you are starting from autogen.sh you will need a few additional
tools that comprise the GNU Autotool toolset:
autoconf (2.50+, e.g. 2.59)
automake (1.6+, e.g. 1.9)
libtool (1.4+, e.g. 1.5)
All three of those have implicit dependencies on things like m4, perl,
cpp, and more.
If you installed automake version 1.4, you will need to install 1.9
and update the alternatives entry for automake so that it refers to
version 1.9 and not version 1.4:
sudo update-alternatives automake /usr/bin/automake-1.9
PPC64 Linux
-----------
If you happen to be installing on a ppc64 Linux system, the binaries
will not correctly resolve without being installed first. Be sure to
install before testing applications.
Som sagt så finns det möjlighet enligt vad jag förstår så frågan står kvar vad gör jag för fel??
he Installation Guide to BRL-CAD
=================================
Please read this document if you are interested in installing BRL-CAD.
This document covers the basics of installing BRL-CAD from either a
source or binary distribution. Please see the 'Reporting Problems'
section if you run into any trouble installing BRL-CAD.
Some platforms have additional platform-specific documentation
provided in the doc/ directory of the source distribution that should
be consulted if that is the platform you are installing on. This
presently includes the following:
doc/README.MacOSX -- Apple Mac OS X
doc/README.IRIX -- SGI IRIX and IRIX64

QUICK INSTALLATION
------------------
If you downloaded a binary distribution of BRL-CAD for your system,
please read the INSTALLING FROM BINARY section of this document down
below. The rest of this quick installation section is only relevant
to source code distributions of BRL-CAD.
For the impatient or simplistic, the following should compile, test,
and install an optimized BRL-CAD quickly into the /usr/brlcad
directory. If you have a configure script, run the following:
./configure --enable-optimized
make
make benchmark
make test
make install # as root, e.g. sudo make install
If you don't have a configure script, run the following to generate
the script then proceed with the steps above:
sh autogen.sh
If any of the listed steps fail, then something unexpected happened.
See the REPORTING PROBLEMS section of this document to report the
problem or the INSTALLING FROM SOURCE section for more comprehensive
instructions.
Once installed, add /usr/brlcad/bin to your path, and you should be
able to run one of the 400+ applications that constitute BRL-CAD. For
example, to run the MGED solid modeler:
PATH=/usr/brlcad/bin:$PATH ; export PATH
mged
If you use tcsh or another C-shell based command shell, use this
instead:
set path=( /usr/brlcad/bin $path ) ; rehash
mged
INSTALLING FROM BINARY
----------------------
There are a variety of different kinds of binary distributions of
BRL-CAD. Some of the binary disributions are sufficiently generic and
are simply a binary commpressed tarball distribution. Others are
specific to a particular platform such as Debian, Mac OS X, FreeBSD,
and Windows etc.
Generic Binary Distributions:
For the unspecialized binary distributions that are basically
compressed tarballs of the installation root, they should contain the
entire hierarchy of the distribution. That is to say that they
contain /usr/brlcad in it's entirety so that if you decompress, you
will have a `usr' directory that contains a single `brlcad' directory:
gunzip brlcad-7.2.4_linux_ia64.tar.gz
tar -xvf brlcad-7.2.4_linux_ia64.tar
sudo mv usr/brlcad /usr/.
Of course, there are other compression options possible including zip
and bzip2. By default, BRL-CAD expects to be installed into
/usr/brlcad and MGED is not relocateable by default. It's recommended
that you start from a source distribution if you would like to install
into an alternate installation location.
However, if you do desire to install and run BRL-CAD from a different
location, give it a try..
The only problems encountered should be
with running the MGED solid modeler where you will need to set the
BRLCAD_ROOT environment variable to your different install location
(e.g. /usr/local). If this doesn't work (some platforms are more
problematic than others), you will need to compile and install from a
source distribution.
Mac OS X Disk Mounting Image:
Mount the .dmg and run the Installer .pkg contained therein. This
will install into /usr/brlcad and will only require confirming that
your environment is set up properly (i.e. add /usr/brlcad/bin to your
path) as described in this document's Installation Options section.
INSTALLING FROM SOURCE
----------------------
There are a couple means to obtain the BRL-CAD sources, usually via
one of the following starting points:
1) from a SVN checkout/export, or
2) from a source distribution tarball
Using the latest SVN sources is recommended where possible, since it
will have the latest changes. See the corresponding section below for
details on how to install from either starting point.
Starting From a SVN Checkout/Export:
If you have obtained the BRL-CAD sources from the SVN revision control
system, you will need to prepare the build for configuration:
sh autogen.sh
This step requires that you have the GNU Build System (GBS) installed,
which includes a sufficiently recent version of Autoconf, Automake,
and Libtool. Running autogen.sh will verify that the versions of each
are sufficient and will generate the `configure' script. If you do
not have sufficient versions of the GBS components installed, you will
either need to install/ugrade them, run autogen.sh on another system
and them copy the files over, or start with a source tarball
distribution (where autogen.sh is automatically run for you).
Once autogen.sh is sucessfully run somewhere, you can continue with
the steps shown next for starting from a source distribution.
Starting From a Source Distribution:
There are many different ways to build BRL-CAD and depending on what
you need/want will determine which configuration options you should
use. See the CONFIGURATION OPTIONS section below for details on how
to go about selecting which options are appropriate for you.
By default, the default configuration will prepare the build system
for installation into the /usr/brlcad directory (the --prefix option
may be used to change that). This tradition goes back a couple
decades and is a convenient means to isolate the BRL-CAD solid
modeling system from your system, resolves conflicts, facilitates
uninstalls, and simplifies upgrades. The default configuration is
performed by running the `configure' script:
./configure
By default, an unoptimized debug build of BRL-CAD will be configured
for compilation. To obtain an optimized build (for example, for
BRL-CAD Benchmark performance evaluation), use the --enable-optimized
configure option:
./configure --enable-optimized
By default, all components and functionality will be built except
jove. However, BRL-CAD does require and include several 3rd party
components. If your system does not include a sufficient version of
those required 3rd party components, they will be automatically
configured for compilation. You can force any one of those components
on or off via --enable-FEATURE and --disable-FEATURE arguments to
configure:
./configure --enable-termlib --disable-png
See the CONFIGURATION OPTIONS below for more details on all of the
possible settings.
Once configured, you should be able to succesfully build BRL-CAD via
make:
make
See the COMPILATION OPTIONS section in this document for more details
on compile-time options including options for parallel build support.
Testing the Compilation:
Once the compilation is complete, you can test it before and after
installation. To test a compilation of BRL-CAD before installation,
you can run the BRL-CAD benchmark. The benchmark will report if the
results are correct, testing a majority of the core functionality of
BRL-CAD in addition to testing your system's performance:
make benchmark
See the TESTING FUNCTIONALITY section of this document for more
details on how to ensure that the build completed successfully and
additional tests that may be run.
Installing the Compilation:
After the build successfully completes and assuming the benchmark also
produces correct results, installation may begin. Like any package,
you must have sufficient filesystem permissions to install. To
install into a system location, you can generally either become a
super user via the su or sudo commands:
sudo make install
See the INSTALLATION OPTIONS section of this document for more details
on BRL-CAD installation options and post-install environment
preparations.
CONFIGURATION OPTIONS
---------------------
Variables can be set in the environment passed to `configure'.
However, the build may run configure again during the build, and the
customized values of these variables may be lost. In order to avoid
this problem, you should set them in the `configure' command line,
using `VAR=value'. For example:
./configure CC=/usr/ucb/bin/cc
will cause the specified executable program to be used as the C
compiler.
By default, BRL-CAD is configured to build the entire package and will
install completely isolated into the /usr/brlcad directory.
Configuration will prepare the build for an unoptimized compilation by
default and will attempt to utilize required system libraries if they
are available, otherwise compiling the required library dependencies
as needed. Run `./configure --help' for a list of all of the possible
configuration options. See the ENABLE OPTIONS and WITH OPTIONS lists
below for the arguments presently available to configure in more
descriptive detail.
ENABLE OPTIONS:
The below --enable-* options can be used to enable or disable aspects
of compilation that relate to what and how BRL-CAD will be compiled.
Using --disable-* is the same as --enable-*=no and either can be used
interchangably. As BRL-CAD is a large bazaar of functionality, there
are a lot of options and configurations possible. See the section
labeled WITH OPTIONS below for a list of options that enable/disable
optional system functionality.
