--with-event-libevent-dir

[Craig Fairhurst]

Hi

I'm passing --with-event-libevent-dir to configure and its not seeing lib event and failing. See below:

Not sure why this isn't working. Nothing I try works, including installing -dev packages.

I'm running CentoOS 6.

Hi,

the script is searching for

/usr/lib64/include/event2/event.h
/usr/local/include/event2/event.h
/usr/include/event2/event.h
/opt/include/event2/event.h
/opt/local/include/event2/event.h

where /usr/lib64 comes from --with-event-libevent-dir option.

CentOS 6 libevent-devel package installs the C headers into /usr/include/event2. So to get the headers we need --with-event-libevent-dir=/usr.

The script implies that the libraries should be found in one of the following places:

$EVENT_DIR/lib64/event2
$EVENT_DIR/lib64

where $EVENT_DIR comes from --with-event-libevent-dir option.

The libevent package installs the libraries into /usr/lib64. So to get the libraries we still need --with-event-libevent-dir=/usr.

Thus, we just need to install libevent and libevent-devel packages, then rebuild the extension using --with-event-libevent-dir=/usr.

I guess you fixed it.
