Situation:
Solaris 8 on Sparc. Fresh Download of php-sources, Version 5.1.2. unpack, "./configure --with-apxs2=/usr/local/apache-2.0.55/bin/apxs" results in a "Build complete."
After that I make a "make test", there are quite some tests and at one point the tests result apparently in an unexpected state. Then, the testsuite wants to report this and wants to use "bison" - which isn't installed usually on a Solaris machine. So there should be a check against bison in the configure-script (this was already a problem in php3, as I can see in the bug database).

Apparently you forgot to tell us what exactly the problem is.

And you know that because you see some error, right?
Or is it a secret?

*sigh* since this machine has no internet-access I hoped it would be enough to tell that php expects bison but doesn't check wether it's there.

but here it is: I do the make test, there seems to be a problem:

You may have found a problem in PHP.
We would like to send this report automatically to the
PHP QA team, to give us a better understanding of how 
the test cases are doing. If you don't want to send it
immediately, you can choose "s" to save the report to
a file that you can send us later.
Do you want to send this report now? [Yns]: y

sh: bison: not found
PHP Warning: PHP Startup: /: Unable to initialize module
[..]

If you look into "run-tests.php" line 717, it checks the version of bison if a test fails. And this check fails (of course) if bison is not installed. I don't know why php wants to have bison, but at least run-tests.php expects it.

So basically the problem could be solved by changing this line to `bison --version 2>/dev/null` ?

To be honest, I have no idea, where and why php needs bison and/or yacc. configure is apparently checking for bison but it ignores it when it isn't installed and uses yacc instead. So I'd guess to ask one of the developers wether bison is needed or not.

This bug has been fixed in CVS.
