32 CONTENTS
7.2.1.1 Software requirements
• Linux x86 (32-bit)
– The 32 bit version will run on a 64-bit Linux system if the other library requirements are met with 32-bit
libraries. I.e. you cannot mix 64 and 32-bit libraries and applications.
– Versions for Linux on x86-64 (64-bit), PowerPC, ARM or MIPS may be possible on request.
• GNU compiler version GCC 3.2.x or greater and associated tool chain.
Note
Our own modified version of libusb has been statically linked to our library and is therefore included, so
libusb is not a requirement.
7.2.1.2 Other requirements
• libexpat (http://expat.sourceforge.net)
• Optional: wxWidgets 2.6.x (non Unicode) for the wxWidget test programs.
• Optional: udev or hotplug subsystem (see also 4. below).
As an example of which packets need to be installed, consider OpenSuSE 10.1:
• The compiler used is gcc 4.1.0 and may need to be installed. Use the "gcc" und "gcc-c++" RPMs. Other
RPMs may be installed automatically due to dependencies (e.g. make).
• libexpat will almost definitely be installed already in any software configuration. The RPM is called "expat".
• Install the wxWidgets "wxGTK" and "wxGTK-develop" RPMs. Others that will be automatically installed due
to dependencies include "wxGTK-compat" and "wxGTK-gl". Although the MATRIX VISION software does not
use the ODBC database API the SuSE version of wxWidgets has been compiled with ODBC support and the
RPM does not contain a dependency to automatically install ODBC. For this reason you must also install the
"unixODBC-devel" RPM.
• OpenSuSE 10.1 uses the udev system so a separate hotplug installation is not needed.
7.2.1.3 Hardware requirements
USB 2.0 Host controller (Hi-Speed) or USB 1.1 Host controller will also work (with a max. frame rate of 3 to 4 fps
at 640x480 only).
Note
We have noticed problems with some USB chip sets. At high data rates sometimes the image data appears
to be corrupted. If you experience this you could try one or more of the following things.
• a different PC.
• a plug-in PCI/USB-2.0 card without any cables between the card and the USB connector.
• turning off the image footer property - this will ignore data errors.
Note
The driver contains libraries for Linux x86 (32 bit) or Linux 64-bit (x86_64). There are separate package files
for systems with tool chains based on GNU gcc 3.2.x - 3.3.x and those based on GNU gcc >= 3.4.x. gcc 3.1.x
may work but, in general, the older your tool chain is, the lass likely it is that it will work. Tool chains based on
GNU gcc 2.x.x are not supported at all.
GCC 4.x (4.1.0) has been tested on OpenSuSE 10.1 and should work on other platforms.
This version (32-bit only) will also run in a VMware (http://www.vmware.com) virtual machine!
