<p>Dear Brendan,</p>
<p><br>
</p>
<p>Thank you for the answer but during the building phase (i.e. after that I launch build.sh) I get the following error:</p>
<p><br>
</p>
<p></p>
<div>panda/plugins/myfirstplugin.c:<wbr>42:13: error: ‘CPUState’ has no member named ‘regs’
<br>
</div>
<div> pc, env->regs[R_EAX]);</div>
<div><br>
</div>
<div>All the other files are correctly compiled so I don't have any idea. <br>
</div>
<div>Obviously env is a CPUState* variable. My included files are:</div>
<div><br>
</div>
<div>
<div>#include "panda/plugin.h"<br>
#include "panda/plugin_plugin.h"<br>
#include "cpu.h"<br>
#include "qemu-common.h"</div>
<div><br>
</div>
<div>Do you know what is the problem?</div>
<div>greetings to all<br>

<div dir="ltr"><span class="">Put it in the panda/plugins directory and then add the name of the plugin to panda/plugins/config.panda. Then just run build.sh as normal and your plugin will be built with the others. It is also possible to have an "external plugins" path, see

<p>Hi all,</p>
<p><br>
</p>
<p>I have written my first plugin but I don't know what I've to do now. How can I compile and build it so that it can be called in command line through the '-panda' option? (i.e. exactly like the other plugins already written)</p>
<p><br>
</p>
<p>Thank you<br>
