“Cannot find config.m4.” while running phpize in the installation of apd using pecl

问题

I'm trying to get access to rename_function in PHP, and for that I need PECL APD. I'm running Ubuntu 14.04 LTS.

I'm trying to run sudo pecl install apd, but I'm getting:

downloading apd-1.0.1.tgz ...
Starting to download apd-1.0.1.tgz (36,643 bytes)
..........done: 36,643 bytes
15 source files, building
running: phpize
Cannot find config.m4.
Make sure that you run '/usr/bin/phpize' in the top level source directory of
the module

If the command failed with 'phpize: not found' then you need to install php5-dev package. You can do it by running 'apt-get install php5-dev' as a root userERROR: `phpize' failed

Should I be running this command from a certain directory?

This time I tried it with verbose options turned on, in case there is a clue in the logs:

sudo /usr/bin/pecl -vvvvv install apd

This will be a short summary of everything to is a precondition to run APD as a PHP profiler, I hope it will help your needs. This summary applies for PHP 5.6.2 APD 1.0.1 and might be incorrect for other versions.

First of all do not start it if you didn't ensure these two:

Deactivate Zend platform or any other PHP optimizer. In general you need to disable all Zend extensions.
Install a debugging enabled version of PHP (--enable-debug)

If you have a working PEAR setup you need to setup APD like in this article. Don't forget to try out distribution packages either. Otherwise APD's build as following:

Extract tarball.
Change directory in tarball.
Run <apache root>/bin/phpsize
Run ./configure (Add --with-php-config=<apache root>/bin/php-config if configure fails.)
Compile and install everything using
```
make
make install
```

Edit php.ini and add at least

zend_extension=/apd.so
apd.statement=1
apd.tracedir=/tmp/apd-traces

Create the output directory specified in php.ini

Now you'll need to restart Apache but before you do, check that the APD extension works fine. To do simply run PHP

/bin/php

No warning should be given if extension is loaded properly. If you get error message something like the "apd.so" extension couldn't be loaded there is a problem. Check if you compiled against the correct Apache/PHP version and using the same right now.

If PHP doesn't complain about anything enter:

<?php phpinfo(); ?>

and check for some lines about APD. If you find them you are done.

You'll also need some traces so to start tracing you need to your Apache to allow the PHP module to load APD. Next you'll need to identify the script to trace. Add the APD call at the top of the script:

apd_set_pprof_trace();

Then make some requests and remove the statement again to avoid causing further harm. Now have a look at the trace directory. You should find files with a naming scheme of pprof[0-9]*.[0-9] here. Decode them using the pprofp tool from your APD source tarball. Example:

/bin/php /pprofp -u

Redirect stdout if necessary. Use -t instead of -u (summary output) to get calling trees. When you create traces with -t you get a summary output too, but it doesn't contain the per-call durations. I suggest to always create both a call tree and a summary trace.

Hope that helps, I recommend you hardly to read the link mentioned above.

EDIT:

The phpize command is meant to be run at the top level of an extension source dir (this source dir should contain a file name config.m4). See this for more info.

As per error:

If the command failed with phpize: not found then you need to install php5-dev package.

You can do it by running apt-get install php5-dev as a root user

I think you should install module development for PHP via:

sudo apt-get install php5-dev

This should provide you with phpize binary necessary to compile the Pecl extension sources. And make sure it's in your PATH.
