</div></div>Not sure about this... we don't guarantee stable plugin-API between<br>
major weston releases (1.1 and 1.2, for example) so it doesn't make<br>
sense to check if the version is at least 1.2.2, for example. Within<br>
a stable branch, we done change the plugin API/ABI, so what you can<br>
check for is a specific major and minor version and a minimum micro<br>
version.<br>
<br>
I'd suggest something linke<br>
<br>
#define WESTON_VERSION_AT_LEAST(major, minor, micro) \<br>
(WESTON_VERSION_MAJOR == (major) && \<br>
WESTON_VERSION_MINOR == (minor) && \<br>
WESTON_VERSION_MICRO >= (micro))<br>
<br>
Does that work?<br>
