Description:
------------
5.4.0 bundle configured with only one option: --enable-dtrace

The configure script runs fine and the build finishes without error.  However, 
the next invocation of 
make (probably from trying to run 'make install') fails with the following 
error:


[jack@fjpe6maa ~/php-5.4.0]$ make install
gcc   /home/jack/php-5.4.0/Zend/zend_dtrace.d.o   -o /home/jack/php-

5.4.0/Zend/zend_dtrace.d

What's happening here is that make has determined that the file 
Zend/zend_dtrace.d is out of date and 
must be rebuilt.  It matches a built-in implicit rule that ends up running:
gcc   /home/jack/php-5.4.0/Zend/zend_dtrace.d.o   -o /home/jack/php-
5.4.0/Zend/zend_dtrace.d

This command fails with the error that you see, but it also clobbers 
zend_dtrace.d

Here's a bit more detail from 'make -d':

I was able to work-around this issue by disabling built-in implicit rules with 
'make -r'.  Obviously, I 
had to recover the clobbered file before this worked.

The offending Makefile may be seen here: http://harschsystems.com/bugs/php-
54_sol_dtrace/Makefile.txt

For reference:
On solaris (and solaris-derived) systems, the compilation of USDT dtrace probes 
goes something like this:

$ dtrace -h -o foo_provider.h -s foo_provider.d
>> Generates header file
$ gcc -c foo_src.c
$ dtrace -G -o foo_provider.o -s foo_provider.d foo_src.o
>> Generates object file 
$ gcc -o a.out foo_provider.o foo_src.o

For more detail, see: http://dtrace.org/blogs/dap/2011/12/13/usdt-providers-
redux/

This test system is running an Illumos variant (derived from OpenSolaris).
gmake 3.82

This bug deals with the same part of the build system as another bug I filed 
back in the 5.3 dev branch:
https://bugs.php.net/bug.php?id=53338

As these were the only 2 times I've tried compiling php with dtrace, I'd say 
there should be better test 
coverage of solaris + --enable-dtrace.

Expected result:
----------------
make shouldn't delete source files

Actual result:
--------------
make deletes a source file, rendering the build system inoperable.

I can confirm I'm seeing this problem too on both Solaris 10 and SmartOS.
 [2012-05-08 04:35 UTC] mike at harschsystems dot com 
I've seen the same failing behavior on 5.4.1 as well.  It's worth noting that 
gmake exhibits this failure mode while regular (non-GNU) make works fine.  So, the 
2 workarounds are:

1.) run gmake with the '-r' option
or
2.) run non-GNU make instead of gmake

I see what the problem is but cannot reproduce it myself with 5.5.0alpha1. 
Please try the 5.5.0alpha snapshots from http://downloads.php.net/dsp and 
provide me with 'uname -a' and 'gmake --version'.

./configure && gmake works fine for me on

$ uname -a
SunOS foo 5.11 11.0 i86pc i386 i86pc Solaris

which is a Oracle Solaris 5.11.

$ gmake -- version
GNU Make 3.81

This bug is still present in 5.5.0 alpha 1.  I just reproduced it on Oracle 
Solaris 11.1.

You must run the configure script with '--enable-dtrace' to trigger the failure 
(and be using gnu make as mentioned already).

After some investigation, I think the easiest patch is below.  This has only been tested on Linux in one install scenario.  I'll continuing testing after the weekend.

The suggested patch does appear to fix the clobber problem on illumos.

This clears the way to hit bug 62692 (which also breaks dtrace on solaris-based 
systems).

Let's fix the issue of not applying the 'dtrace -G' step to the files in 
Zend/.libs so that we can reach a working state for dtrace on solaris.

Thank you for the report, and for helping us make PHP better.

Building on solaris/illumos is still broken per the description in bug 62692.  I 
don't know how it reached 'verified' state but it needs to be re-opened and 
evaluated.
 [2013-08-14 18:52 UTC] sixd@php.net 
"Verified" status is open and the problem confirmed to occur.
