<div dir="ltr">This looks more like a compile time feature check than runtime. The PKG_CONFIG() api number which had the initial set of QEMU requirements was 3 (i.e, PKG_CONFIG(..,glusterfs-api>=3,..). The new updates for Samba requirements has api number 4. Depending on whether discard support makes it before the next release (and api numbers gets published) or not, glfs_discard() would either be available in 4 or 5. Also, you might also want to add a second AC_CHECK_FUNC macro in <a href="http://configure.ac">configure.ac</a> to be doubly sure.<div>

Hi,<br>
<br>
What is the best way to determine if I am running (or linked to) a<br>
particular version of libgfapi/glusterfs ?<br>

<br></div>
This would be a runtime determination, right? We are evolving versions for libgfapi that is independent of the package version.<br>

Requirement: If I want to support the use of glfs_discard() from QEMU,<br>
I should be doing it only if QEMU is linked to a version of libgfapi<br>
that supports glfs_discard().<br>
<br>
</blockquote>
<br></div>
Maybe a new api glfs_get_version() can be evolved to determine libgfapi capability at runtime?<br>
