#48853 [Opn->Fbk]: Using bundled pcre fails if no unbundled headers are available on the system

New Comment:
Considering the error really happens inside Apache headers, how is this
a PHP bug? From your compile error:
/usr/src/redhat/BUILD/php-5.2.9/sapi/apache2handler/mod_php5.c:26:
/usr/include/httpd/httpd.h:43:23: pcreposix.h: No such file or
directory
Blindly adding unnecessary include paths to fix something outside our
control is not very wise..

I narrowed the offending configure option down to
--with-apxs2=/usr/sbin/apxs
Afaik I need to specify that option to build the apache module... Or am
I mistaken?

"no feedback" means you didn't provide the feedback from the correct
tab but failed and used "Add Comment" instead (the right place is "Edit
Submission" for you since you reported this).
Now, can you please provide the actual configure line? Something I can
copy'n'paste and which has ONLY the required options to reproduce this.
Note: I can not reproduce this with or without the pcre headers around..

I am unsure why this report was labeled "No Feedback" as I provided the
requested configure line within 2 hours after the request was made. I
was not aware of this state change as I haven't received an email
indicting this.
Doing a quick checkup in SVN it seems this issue was not fixed. In
5.3.2 the block where $PHP_PCRE_REGEX" = "yes" tests true got moved to
the bottom of the file, but the required include path still seems not to
be provided.
To shortly restate the issue:
On a system where no other pcre headers are available the headers of
the bundled pcre are not found due to a missing include path and the
build fails.
Since on most systems pcre headers will be available you will need to
explicitly remove the pcre headers provided by the build system
(pcre-devel package or similar) to reproduce this issue. If any other
pcre headers than the bundled ones are available on the system the build
will use those and succeed where it shouldn't.
Build still fails on CentOS(/RHEL)-4 for php-5.2.12. Old headers have
been removed using rpm -e --nodeps pcre-devel. I am aware this is an
unusual situation, but what is the point of building against the bundled
pcre source when the build uses the (old and wrong) headers provided by
the build system? PHP should find and use the headers of the bundled
pcre when building against these, not some random headers available on
the system.

As I said, I'm not using a --with- or --without-pcre option. The other
options seem not very relevant in this context but I'll paste the line
from the used rpm spec file here. %configure translates to configure ;)

The OS is not really relevant, just the reason there are no unbundled headers available as there's a version mismatch with the bundled headers. Using the bundled pcre library by not supplying any pcre configure options. When the unbundled (upgraded/matching) headers are available on the system the build succeeds. However, if no unbundled headers are available httpd.h cannot find the bundled pcreposix.h (and other headers). This is *not* an apache issue, the issue is a missing include path in the build. If you compare ext/pcre/config0.m4 an include path is provided in case of an external pcre (although on CentOS it will be found in /usr/include no matter if a path is specifically provided): if test "$PHP_PCRE_REGEX" != "no"; then if test "$PHP_PCRE_REGEX" = "yes"; then ...
