If you experience a NullPointer Exception after

launch Eclipse or the debugger from within Eclipse,

78

try adding the following

79

to your <filename>eclipse.ini</filename> file,

80

which is located in the directory in which you

81

unpacked the Eclipse tar file:

82

83

--launcher.GTK_version

Alternatively, you can export the

<filename>SWT_GTK</filename> variable in your

shell as follows:

$ export SWT_GTK3=0

<title>Configuring the Cross-Compiler Options</title>

360

361

<para>

362

Cross Compiler options enable Eclipse to use your specific

cross compiler toolchain.

364

To configure these options, you must select

the type of toolchain, point to the toolchain, specify

366

the sysroot location, and select the target

architecture.

For example, suppose you are an

383

Instead, you just want to use an

384

architecture-specific toolchain on

385

an existing kernel and target root

filesystem.

387

In other words, you have downloaded

When building "Yocto Project SDK Autotools" projects, the

Eclipse IDE might display error messages for

652

Functions/Symbols/Types that cannot be "resolved", even when

653

the related include file is listed at the project navigator and

654

when the project is able to build.

655

For these cases only, it is recommended to add a new linked

656

folder to the appropriate sysroot.

657

Use these steps to add the linked folder:

Select the project.

706

707

Click "Run" to launch QEMU.

708

<note>

709

The host on which you are running QEMU must have

710

the <filename>rpcbind</filename> utility running to be

711

able to make RPC calls on a server on that machine.

712

If QEMU does not invoke and you receive error messages

713

involving <filename>rpcbind</filename>, follow the

714

suggestions to get the service running.

715

As an example, on a new Ubuntu 16.04 LTS installation,

716

you must do the following in order to get QEMU to

717

launch:

718

719

$ sudo apt-get install rpcbind

720

</literallayout>

721

After installing <filename>rpcbind</filename>, you

722

need to edit the

723

<filename>/etc/init.d/rpcbind</filename> file to

724

include the following line:

OPTIONS="-i -w"

</literallayout>

After modifying the file, you need to start the

729

service:

730

731

$ sudo service portmap restart

</literallayout>

<listitem><para>If needed, enter your host root password in

One useful task at this point would be to determine the

<filename>ifconfig</filename> command.

747

The IP address of the QEMU machine appears in the

748

xterm window.

749

You can use this address to help you see which particular

750

IP address the instance of QEMU is using.

<title>Deploying and Debugging the Application</title>

758

759

<para>

760

Once the QEMU emulator is running the image, you can deploy

761

your application using the Eclipse IDE and then use

762

the emulator to perform debugging.

763

Follow these steps to deploy the application.

764

<note>

765

Currently, Eclipse does not support SSH port forwarding.

766

Consequently, if you need to run or debug a remote

767

application using the host display, you must create a

768

tunneling connection from outside Eclipse and keep

769

that connection alive during your work.

770

For example, in a new terminal, run the following:

771

772

$ ssh -XY <replaceable>user_name</replaceable>@<replaceable>remote_host_ip</replaceable>

773

</literallayout>

774

Using the above form, here is an example:

775

776

$ ssh -XY root@192.168.7.2

777

</literallayout>

778

After running the command, add the command to be executed

779

in Eclipse's run configuration before the application

as follows:

export DISPLAY=:10.0

</literallayout>

Be sure to not destroy the connection during your QEMU

785

session (i.e. do not

786

exit out of or close that shell).
