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

342

343

<para>

344

Cross Compiler options enable Eclipse to use your specific

345

cross compiler toolchain.

346

To configure these options, you must select

the type of toolchain, point to the toolchain, specify

348

the sysroot location, and select the target

349

architecture.

For example, suppose you are an

need to build a target image.

365

Instead, you just want to use an

366

architecture-specific toolchain on

367

an existing kernel and target root

368

filesystem.

369

In other words, you have downloaded

Eclipse IDE might display error messages for

634

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

635

the related include file is listed at the project navigator and

636

when the project is able to build.

637

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

638

folder to the appropriate sysroot.

639

Use these steps to add the linked folder:

Select the project.

Select "Folder" from the

Click "Browse" to navigate to the include folder inside

654

the same sysroot location selected in the Yocto Project

Locate and select your image in the navigation panel to

686

</para></listitem>

688

689

Click "Run" to launch QEMU.

690

<note>

691

The host on which you are running QEMU must have

692

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

693

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

694

If QEMU does not invoke and you receive error messages

695

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

696

suggestions to get the service running.

697

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

698

you must do the following in order to get QEMU to

699

launch:

700

701

$ sudo apt-get install rpcbind

702

</literallayout>

703

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

704

need to edit the

705

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

706

include the following line:

OPTIONS="-i -w"

</literallayout>

After modifying the file, you need to start the

711

service:

712

713

$ sudo service portmap restart

</literallayout>

</note>

</para></listitem>

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

726

One useful task at this point would be to determine the

IP Address for the user-space NFS by using the

728

<filename>ifconfig</filename> command.

729

The IP address of the QEMU machine appears in the

730

xterm window.

731

You can use this address to help you see which particular

732

IP address the instance of QEMU is using.

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

740

741

<para>

742

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

743

your application using the Eclipse IDE and then use

744

the emulator to perform debugging.

745

Follow these steps to deploy the application.

746

<note>

747

Currently, Eclipse does not support SSH port forwarding.

748

Consequently, if you need to run or debug a remote

749

application using the host display, you must create a

750

tunneling connection from outside Eclipse and keep

751

that connection alive during your work.

752

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

753

754

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

755

</literallayout>

756

Using the above form, here is an example:

757

758

$ ssh -XY root@192.168.7.2

759

</literallayout>

760

After running the command, add the command to be executed

761

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

767

session (i.e. do not

768

exit out of or close that shell).

Eclipse is helpful in that it auto fills your application
