#73 Installation


I have tried to install Brlcad as outlined: (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.) but keep receiving file not found or commands unknown. Tried to launch it in X11 and Terminal same thing. I see others have had the same issue but I cant find a good tutorial to get it up and running. I would really like to use this program.

    This is what I get in X11. bash-3.2$ /usr/brlcad/rel-7.12.2/bin/mged
    bash: /usr/brlcad/rel-7.12.2/bin/mged: Bad CPU type in executable

    Until a new binary can be generated, have you considered building BRL-CAD yourself? Sean has put a lot of work into making the Mac build easier. And taking good notes would help improve it more.

    The error you're seeing means it was built for a different CPU than you have. We typically don't build PPC binaries (most have moved on to x86_64). Building from source would be the best approach, as outlined in http://brlcad.svn.sourceforge.net/svnroot/brlcad/brlcad/trunk/INSTALL. You will need Xcode and X11 installed.

    The typical sequence of events after downloading the source tarball:
    $ tar zxvf brlcad-7.18.4.tar.gz
    $ cd brlcad-7.18.4
    $ ./configure --enable-optimized
    $ make -j2 all install

    If you want to verify the file type, you can use "file </path/to/file>" (i.e. file /usr/brlcad/bin/rt), and the machine architecture by running "uname -m"
