Sujet Installer la librairie D2XX (Linux) pour émetteur DMX sur eeepc

Installing the D2XX shared library and static library.
------------------------------------------------------

1. tar xfvz libftd2xx1.1.12.tar.gz

This unpacks the archive, creating the following directory structure:

build
arm926
i386
x86_64
examples
libusb
ftd2xx.h
WinTypes.h

2. cd build/arm926

3. sudo -s
or, if sudo is not available on your system:
su

Promotes you to super-user, with installation privileges. If you're
already root, then step 3 (and step 7) is not necessary.

4. cp lib* /usr/local/lib

Copies the libraries to a central location.

5. chmod 0755 /usr/local/lib/libftd2xx.so.1.1.12

Allows non-root access to the shared object.

6. ln -sf /usr/local/lib/libftd2xx.so.1.1.12 /usr/local/lib/libftd2xx.so

Creates a symbolic link to the 1.1.12 version of the shared object.

7. exit

Ends your super-user session.



Building the shared-object examples.
------------------------------------

1. cd examples

2. make -B

This builds all the shared-object examples in subdirectories.

With an FTDI device connected to a USB port, try one of the
examples, e.g. reading EEPROM.

3. cd EEPROM/read

4. sudo ./read

If the message "FT_Open failed" appears:
Perhaps the kernel automatically loaded another driver for the
FTDI USB device.

sudo lsmod

If "ftdi_sio" is listed:
Unload it (and its helper module, usbserial), as follows.

sudo rmmod ftdi_sio
sudo rmmod usbserial

Otherwise, it's possible that libftd2xx does not recognise your
device's Vendor and Product Identifiers. Call FT_SetVIDPID before
calling FT_Open/FT_OpenEx/FT_ListDevices.



Building the static-library example.
------------------------------------

1. cd examples/static

2. rm lib*

Cleans out any existing libraries built for another target.

3. cp /usr/local/lib/libftd2xx.a .

4. make -B

5. sudo ./static_link

Building the shared-object examples.
------------------------------------

1. cd examples

2. make -B
