php5.4之后安装xhprof出现make: * [xhprof.lo] Error 1

百度有点坑，
卡了一会儿后在yahoo上搜到了解决方案，
在这写个备忘。

We use xhprof to profile our web application framework. The pecl
installer was failing with [xhprof.lo] Error 1 in the make phase
with PHP 5.4. Here’s how to fix that.

Currently, trying sudo pecl install xhprof-beta throws the following
errors in the make phase for PHP >= 5.4:

According to a PHP bug report, this issue was fixed by Facebook but
not made available on pecl, so you will need to install from the
xhprof github repo, like so:

wget https://github.com/facebook/xhprof/archive/master.zip unzip master.zip ./configure make sudo make install

And enable the module in your php.ini, where xhprof.output_dir is
the directory into which profiles will be generated.

[xhprof] extension=xhprof.so xhprof.output_dir="/var/tmp/xhprof"

And restart apache, with either of the following two: sudo service
apache2 restart
or
sudo apachectl graceful

Existing users who have upgraded to PHP 5.4 may opt for this xhprof-0.9.2 patch.
